Galileo Initial Services Open Service and SAR/Galileo Enhanced Services Performance Reports covering the first quarter of 2020 are available in the Electronic Library of the European GNSS Service Centre web portal.  

These quarterly reports provide the public with the latest information on the Galileo OS and SAR/Galileo Services measured performance statistics with respect to their Minimum Performance Levels (MPLs) (as declared in their respective Galileo Service Definition Documents: OS-SDD and SAR-SDD). Both SDDs can be found in the Programme Reference Documents section of the GSC web portal. It should be noted that this SAR/Galileo Service Performance Report is the first one following the declaration of the SAR/Galileo Enhanced Services and the publication of the updated SDD last January.

Some highlights from the Q1-2020 performance reports:  

• Initial Service OS:       
  • Galileo Initial Open Service Ranging Performance: This is measured based on the Availability of the Galileo SF/DF Ranging Service [between 96.29% (all signals, March) and 96.42% (SIS E5a and Dual Frequency combination E1-E5a, February)], Per-slot Availability of Healthy Signal in Space for each Galileo operational satellite [low values were observed for GSAT-209 (86.71% in February) and GSAT-103 (with F/NAV and I/NAV SIS availability of respectively 45.34% and 51.52% during March)] and the Galileo Signal in Space Ranging Accuracy [for individual space vehicles: worst case value of 0.41 [m] for DF in February and 0.68 [m] for SF in February and March; best case values of 0.15 [m] for DF in January and 0.22 [m] for SF in February and March].       
  • Galileo UTC and GGTO Dissemination and Determination Performance: The Galileo UTC Determination Service Availability reached a monthly value of 100% during the entire quarter, exceeding the MPL target of 87%. Moreover, the GGTO Determination Availability exceeds the MPL target of 80% over the reported months, reaching 100% in January and March.       
  • Galileo Positioning Performance: This is measured based on the Availability of the Galileo Position Dilution of Precision and the Positioning Service, and the Galileo measured Positioning Performance.       
  • Timely Publication of NAGUs (Notice Advisory to Galileo Users): The timeliness requirements for NAGU publication were met both for Planned and Unplanned events (NAGUs related to planned events need to be published at least 24 hours before the event starts, and those related to unplanned events with a delay of up to 72 hours from the detection of the unplanned event). A total number of 8 NAGUs have been published on the GSC web portal in the reported period.  
• Enhanced SAR/GALILEO Service:       
  • Availability of SAR/Galileo:           
    • Forward Link Service: 99.9% for the reported period (above defined MPLs of 99%).

European standards agency EUROCAE has published ED-270 – Minimum Operational Performance Specification (MOPS) for Unmanned Aircraft Systems (UAS) geo-caging.   The objective of the document is to define minimum operational performance standards for geo-caging tasks. These specifications describe performance without prescribing its design and implementation as far as possible. Compliance with the standard is recommended as one means of assuring that the Function will perform its intended sub-functions satisfactorily under all conditions normally encountered in routine aeronautical operation and will comply with applicable regulations.  

The specification can be found here: https://eshop.eurocae.net/eurocae-documents-and-reports/ed-270/

EUROCAE has recently communicated that their draft standards on “UTM E-Identification” are available for Open Consultation. According to them, Draft ED-282 ” Minimum Operational Performance Standard for UAS E-Identification ” defines minimum requirements for UAS e-Identification systems, specially focusing on the e-Identification function to proivde surveillance information coming from the UAS, either from the GCS or from the aircraft itself. This will be provided to other UAS and U-space services.

EUROCAE stated that compliance with this standard is recommended as one means of assuring that the equipment will perform its intended function(s) satisfactorily under all conditions normally encountered in routine aeronautical operation. It is designed to ensure that equipment (either the unmanned aircraft system or a sub-set of hardware and /or software components implementing the function) compliant to it, will be able to demonstrate safety and suitability for operational use.

The deadline for the comments submission is 05/08/2020. (https://www.eurocae.net/news/posts/2020/june/eurocae-open-consultation-ed-282/)

The European Commission has published the Commission Implementing Regulation (EU) 2020/746 of 04 June 2020 amending Implementing Regulation (EU) 2019/947 where postponing dates of application of certain measures due to the COVID-19 pandemic.

Confinement and changes in the working conditions and availability of employees combined with the additional workload required to manage the significant negative consequences of the COVID-19 pandemic for all stakeholders are impairing preparations for the application of these Implementing Regulations.

A delay in executing the different tasks required for the proper and timely implementation of Commission Implementing Regulation (EU) 2019/947, notably the establishment of registration systems that are digital and interoperable, as well as the adaptation of authorisations, declarations and certifications issued on the basis of national law, is inevitable as a consequence of the COVID-19 pandemic.

The standardisation process and other related activities led by the industry and standardisation bodies, such as preparation of testing methodologies, or the testing of technical features, such as the remote identification, has been delayed. This in turn will have a negative impact on the capacity of manufacturers to put on the market unmanned aircraft systems meeting the new standardised requirements in accordance with Commission Delegated Regulation (EU) 2019/945

All UAS types should thus be allowed to continue to operate under the existing conditions for an additional 6 months. Therefore, the dates of application of Implementing Regulation (EU) 2019/947 should be postponed accordingly in order to allow UAS operators to be able to use UAS not complying with Delegated Regulation (EU) 2019/945 for additional 6 months

The European Space Programmes are playing a key role in managing the COVID-19 pandemic and in particular in supporting emergency and medical operations in all weather, anytime, when they are most needed. We have talked to air ambulance and emergency operators using EGNOS about their experience and how EGNOS is helping them to take care of EU citizens, operate more effectively in these difficult times and save lives.

During this difficult period, the perception of our world has changed and we recognise the health sector and care givers as our new heroes. When patients from remote areas need to be taken to a hospital at night, in difficult weather situations and life is at stake, EGNOS makes the operation safe. Patients with confirmed COVID-19 infection need to be transported in an operation that is safe for patients and crew.  The accessibility and efficiency gains offered by EGNOS make it possible to land in adverse weather conditions and limited visibility, which is a major advantage. The gains on mission time might well make the difference between life and death of a critically ill patient in regions with limited medical services available.

Previously, operators had to fly under visual flight rules, and therefore faced restrictions in difficult weather conditions or at night. This type of operation can be implemented at helipads in hospitals without the ground infrastructure costs required in conventional operations. In this way, EGNOS provides a cost efficient and safe solution to transfer patients and medical teams to those hospitals with increased reliability and availability, which is essential to save lives.

The GSA (http://www.gsa.europa.eu) was pioneer in supporting the implementation of EGNOS-based approaches and low-level routes in Europe, and is funding a large number of operations and helicopter upgrades. As of today, 23 operational helicopter approaches are using EGNOS in Italy, Austria, Norway, Italy, Czech Republic, France, Switzerland and Germany. Building on users’ needs, the EGNOS Safety of Life Service Definition Document also explicitly reflects rotorcraft operations and, in particular, EGNOS-based Helicopter Emergency Medical Services (HEMS) operations.

In order to harmonise implementation of operations, the GSA supported the creation of the Five Lives Advisory Group (FLAG) of helicopter users, now consolidated as the European focal point for the coordination of EGNOS-based operations for emergency response. In cooperation with EASA and Eurocontrol, the group now includes more than 40 experts from National Aviation Authorities and Air Navigation Service Providers from all Member States, along with emergency operators and manufacturers working on helicopter operations based on EGNOS. In collaboration with all stakeholders the group has developed a three-year work programme for implementation and support of satellite-based rotorcraft operations and published Safety Guidance material for these operations.

The European Organisation for Civil Aviation Equipment (EUROCAE) has recently announced an Open Consultation regarding the EUROCAE WG-105 SG-53 “ERA – Automation and Emergency Recovery” document, released by the working group WG-105 SG-53 “Automatic protection function for UAS”.

This document provides the Minimum Aviation System Performance Standard for the implementation of an Automation and Emergency Recovery (A&ER) capability for a fixed-wing Remotely Piloted Aircraft System (RPAS) operating in non-segregated airspace and aircraft ground manoeuvring areas. This document is intended to provide globally recognised allocations for performance within the functions of a generic A&ER capability (i.e. both the airborne and the ground-based components of the capability in order to ensure a harmonised approach worldwide leading to enhanced global safety.

The document has been uploaded to EUROCAE’s workspace and it is open for everyone’s feedback until the 27th July 2020.

The European UAS Standards Coordination Group (EUSCG) has announced the release of a new version of the Rolling Development Plan (RDP) for implementing UAS standards by the end of June.

The EUSCG is a joint coordination and advisory group established to coordinate the UAS-related standardisation activities across Europe, essentially stemming from the EU regulations and EASA rulemaking initiatives. The EUSCG provides a link to bridge the European activities to those at international level. According to EUSCG, this document brings together all relevant regulatory and standardisation activities and their status, and is updated regularly in order to maintain visibility and awareness of the progress. It provides a method for the identification and discussion of overlaps, and as a basis for feedback to contributing organisations, to improve overall coordination of standards developments. The process also identifies the technical input from other sources into the standards plan through the interfaces of the EUSCG with the international level. This last version is the fourth one and integrates the roadmap provided by EASA and other civil and military organisations.

The European Organisation for Civil Aviation Equipment (EUROCAE) has recently announced an Open Consultation regarding the  ED-279 “Generic Functional Hazard Assessment (FHA) for UAS and RPAS” DRAFT document, released by the working group WG-105 SG-41 “RPAS System Safety Assessment Criteria”.

The main goal of the document is to develop an UAS/RPAS FHA. This FHA is intended to go through as many different types of UAS as possible aiming at being a useful tool for designers when it comes to make an FHA. In order to achieve this goal, the main functions of an UAS have been detailed and assessed separately from each other. However, the difficulty of generating an FHA that covers every kind of UAS configuration is rather high due to the wide variety of configurations. Consequently, not all essential functions may be included and considered independently.

The document has been uploaded to EUROCAE’s portal and it is open for everyone’s feedback until the 18th June 2020.

EASA has announced that the amendments to the Implementing Regulation (EU) 2019/947 and the Delegated Regulation (EU) 2019/945 have been adopted.

Commission Implementing Regulation (EU) 2020/639 amending Implementing Regulation (EU) 2019/947 as regards standard scenarios for operations executed in or beyond the visual line of sight has been already published in Official Journal of EU and is available on EASA website under the link https://www.easa.europa.eu/document-library/regulations/commission-implementing-regulation-eu-2020639

As for the amendment to Commission Delegated Regulation (EU) 2019/945 as regards the introduction of class C5 and C6 UAS, the document is currently being scrutinized by Parliament and Council. The scrutiny period will be completed on 27th of June, after which the amendment will be published.

The European Aviation Safety Agency (EASA) has published recently the Notice of Proposed Amendment (NPA) 2020-07 entitled “Unmanned aircraft system beyond visual line operations over populated areas or assemblies of people in the ‘specific’ category” .

The objective of this NPA is to clarify the conditions under which unmanned aircraft system (UAS) beyond visual line of sight (BVLOS) operations over a populated area or an assembly of people can be authorised in the ‘specific’ category.

This NPA proposes to amend the Acceptable Means of Compliance (AMC) and Guidance Material (GM) to Commission Implementing Regulation (EU) 2019/947. The AMC and GM to Article 11 ‘Rules for conducting an operational risk assessment’ of said Regulation are proposed to be amended to define the intrinsic UAS ground risk classes (GRCs) for the following operational scenarios:
-BVLOS operations over a populated area; and
-BVLOS operations over an assembly of people.

The proposed amendments are expected to increase safety, improve harmonisation among EASA Member States, and facilitate societal acceptance of UAS BVLOS operations in the ‘specific’ category.  

Currently, comments can be submitted using the Comment-Response Tool (CRT) available at http://hub.easa.europa.eu/crt/. The deadline for submission of comments is the 29th May 2020.  

Following the closing of the public commenting period, EASA will review all the comments received.  Based on the comments received, EASA will develop a decision that amends the AMC and GM to Commission Implementing Regulation (EU) 2019/9475 (the ‘UAS Regulation’). A summary of the comments received will be provided in the explanatory note to the decision. The comments received on this NPA and the EASA responses to them will be reflected in a comment-response document (CRD). The CRD will be published on the EASA website.

During the third webinar hosted by SESAR Joint Undertaking (SJU) at the end of last April, lecturers highlighted the next steps for the safe integration of drones.

A participant involved in research projects highlighted several issues, said: “There is a clear need for the drone services market as a whole to have a secure connection to an authority and to be able to plan and manage drones in one place.” Its team is developing the technology to deliver this and U-space demonstrations reveal potential market opportunities. “We also need standards that everybody agrees to and adheres to, to ensure we have one single way of working that is approved by at least all the member states and preferably across the oceans as well,” he/she added.

In the Netherlands, the first version of U-space is now available. Research is continuing into how it can be used, how coordination activity is managed, how to establish flight priorities, and the possibilities for beyond visual line of sight (BVLOS). “We need to think about how to make sure manned aviation is aware of what drones are doing. U-space services offers a good solution for this. People need to be aware of each other’s activities. The good thing about U-space is you can connect to just one of the services, like the surveillance service, and get information about the traffic without the need for the full deployment.”

Enaire’s Drone Business Chief, reiterated the importance of conspicuity, but added: “Conspicuity is very difficult, especially in low level airspace where you don’t have surveillance. This needs to be developed, but it is a hard topic.” The DOMUS project highlighted the importance of a single “Ecosystem Manager” combined with a federated structure to provide the necessary de-confliction services. This interface between air traffic management and unmanned traffic management is central to tactical coordination. A lot of work still needs to be done according to the U-space Programme Manager. “On the one hand we are happy to see all the work that has been done in short space of time and we expect to release the results in a brochure with data from the project reports by this Summer. At the same time, there is still a lot to do. That is why the material that has been developed in these projects, including technical specifications, will be made available to disseminate more widely.”

The European GNSS Agency (GSA) has launched two calls for papers ahead of its GNSS Raw Measurements Taskforce Workshop, to be held online on 28 May 2020. The first of these calls targets innovative work using raw measurements while the second is related to testing EGNOS Data Access Service (EDAS) corrections in smartphones. EDAS is the EGNOS internet broadcast service, which provides free of charge access to EGNOS data.

In its call for papers related to innovative work using raw measurements, the GSA is particularly interested in recent work using GNSS raw measurements in the field of high accuracy, robustness, testing or monitoring. However, other work in these fields beyond the use of raw measurements is also of interest. Proposals in this call should be submitted by 6 May.

If you are working on innovative solutions in these areas, the GSA wants to hear from you! Proposals, in the form of an abstract (maximum one page in length) should be sent to martin.sunkevic@gsa.europa.eu, clearly indicating the name of the call. In the event that too many proposals are received, the GSA reserves the right to choose the proposals to be presented at the workshop.

The European GNSS Agency (GSA) is working together with the European Commission (EC) on an app to facilitate the movement of goods and freight within the EU in support of the COVID-19 pandemic response. The “Galileo Green Lane” app will ease the flow of freight through borders and enable the efficient transit of critical goods in order to reduce waiting times at Green Lane border crossings.

“At the GSA, one of our key roles is to promote the use of Galileo and to address the economic and societal challenges that Europe faces. The European Commission´s Galileo Green Lane initiative fits this profile exactly,” said Pascal Claudel, Acting Executive Director at the GSA. “By supporting a solution that eases the transport of critical goods across borders, Galileo is making its contribution to help reduce the impact of the coronavirus pandemic on the EU’s economy and its citizens,” he said.

The app will have two interfaces. The first is for border control authorities and provides a real-time visualisation of the overall border situation between a country and its neighbours. In turn, border officials can contribute information to the system by regularly feeding updates into the app on the traffic flow and waiting times at their borders. At the same time, the app will provide Member States with a website, generating reports automatically to demonstrate compliance to the EU on the Green Lanes implementation. The app will also feature a user interface providing drivers with a real-time visualisation of borders of interest to them, through an EU-wide map indicating Green Lane border crossing times. When drivers enter a geo-fenced area within a specified distance to a border, they can receive a notification produced by the border officers on the situation at that border. Their location is collected anonymously only when they are approaching the border and it is solely used to update the overall border picture. Crowdsourced information from different sources is aggregated, including data from the leading European real-time visibility platform Sixfold.

SESAR JU members and partners recently brought to a close two years of research and development (R&D) on how to integrate safely and securely drones across Europe, within the framework of U-space, an initiative by the European Commission.

Organised within the framework of the SESAR Digital Academy, three webinar sessions will present the work of some of these projects addressing the concept of operations for U-Space, critical communications, surveillance and tracking, information management and exchange, detect and avoid, and CNS technologies.

SESAR has scheduled the following webinars:

-28 April 10.00-11.00 From concept to reality
-28 April 14.00-15.00 Taking up the U-Space challenge
-30 April 10.00-11.00 Demonstrating U-Space

For registrations, visit https://www.sesarju.eu/node/3537. The number of participants is limited.

The European Solution for E-GNSS U-Space Service (SUGUS) project is calling respondents to take part in a survey to identify and analyse needs to achieve safe drone integration. The survey is open until 15 May 2020 at https://projectsugus.eu/survey/

The objective of the survey is to identify and capture U-space and EGNSS key stakeholders’ needs in different operational scenarios: U-space Services Technology Suppliers, Operators, UAS and GNSS receiver Manufacturers, UAS Pilots and Operators, Public Bodies, Authorities and Organizations and UAS Test and Training Centers. Results of the survey will help to define a new EGNSS-based Application Programming Interface (API) and contribute to the development of drone standardisation and regulation.

SuguS is a European Commission’s project aimed at accelerating the use of the European GNSS (E-GNSS, EGNOS and Galileo) in the Unmanned Aircraft System (UAS) market, putting in place the necessary means at service provision level for facilitating the operational use of E-GNSS by operators and their approval by the aviation authorities. The project will demonstrate the added value for drone operations of the measures implemented at service provision level and the new EGNSS API. Amongst those benefits are the ability to mitigate the risks of the operations and the facilitation of the mission preparation and authorization processes by the operator.

On 31 March 2018, the EU launched its eCall emergency response system with the publication of the European eCall regulation, requiring all new car and light van types sold in the EU to be fitted with the system.

eCall is activated automatically as soon as in-vehicle sensors detect a serious crash. Once activated, the system dials the European emergency number 112 and establishes a telephone link to the appropriate emergency call centre.

Leveraging EGNSS (Galileo and EGNOS), the system sends the accurate position of the crashed vehicle and the direction of travel to the emergency services, enabling the emergency responders to get to the accident site faster. An eCall can also be triggered manually by pushing a button in the car, for example by a witness to a serious accident.

European Joint Research Centre and the GSA have given support for a quick and smooth uptake by the automobile industry, publishing a set of guidelines to help the eCall industry value chain to pre-test the accuracy of their new devices and understand how to reap the benefits of Galileo.

By speeding up emergency response times by 40% in urban areas and 50% in the countryside, it is estimated that eCall could help prevent 2,500 road deaths and save EUR 26 billion every year.

As of today, in the two years since the launch of the EU’s eCall emergency response system, manufacturers have been quick to implement the life-saving technology, with around 3 million eCall-enabled vehicles already sold in Europe.

The European GNSS Agency has published a document entitled “EGNSS for Drones Operations”. The document has free access.

The document is divided in 5 main sections:

-The first one, entitled Background, speaks about the drone market and the regulatory framework. It also mentions European initiatives as SESAR JU.

-The second block describes current technologies used for drone positioning and navigation and the third one presents benefits and motivation for enabling European GNSS in unmanned air systems. For that purpose, it explains how EGNOS improves the accuracy of the position and presents the results of several flight tests performed by GSA. Lastly, the third section talks about how EU is developing the Galileo High Accuracy Service (HAS).

-The fourth main block presents briefly the current two authentication mechanisms that are planned for Galileo.

-Finally, the document presents different GSA-supported projects. Through R&D funding, the GSA is supporting initiatives related to the implementation of drones: from equipment development, through definition of operations to commercial applications development. Project GAUSS is one of them.

SUGUS is an European Commission project, which involves solutions for E-GNSS U-Space Service. The main goal is to speed up the adoption of EGNOS and Galileo technologies in unmanned aircraft and to ensure safe and efficient coexistence of manned and unmanned air traffic.

U-Space is a set of new airspace-management services and procedures designed to ensure airspace access to UAS while looking out for operational security, the right to privacy and the safety of persons and infrastructure. These services rely on a high level of digitization and function automation, whether onboard the drone itself or part of the ground-based environment.

SUGUS will demonstrate the benefits for drone operations of the measures implemented at service-provision level and the new EGNSS API (European GNSS application programming interface) to be implemented in the project.

These benefits include the mitigation of operating risks, improvement of preparation processes and clearance of the operator’s mission.

The geomatics community has always supported and trusted the European GNSS, proved by the gradual penetration of Galileo in GNSS receivers for surveying and mapping. Nowadays, around 55% of GNSS surveying receivers already support Galileo and around 90% are EGNOS-enabled.

The GSA engages in a systematic process of consultation with the surveying community, and based on this consultation, it produces The Report on Surveying User Needs and Requirements

On the occasion of Global Surveyors Day, The European GNSS Agency (GSA) joins the 2020 Global Surveyors Day, to celebrate and to congratulate the men and women of the surveying profession and their valuable work across a wide range of geomatics applications including land surveying and offshore surveying.

The European Aviation Safety Agency (EASA) has published its U-space opinion containing a draft regulation. As anticipated, the agency has stuck to its original proposal requiring that there should be only one common information service (CIS) provider per U-space airspace (though a State can define many different U-space areas within its airspace) and that a CIS organisation cannot also be the U-space service provider (USSP).

The draft opinion also defines mandatory U-space services: network identification, geo-awareness, traffic information and UAS flight authorisation.

The principle is that ANSPs provide air navigation services (ANS) to manned aircraft while USSPs provide U-space services to UAS operators. Both ANSPs and USSPs are certified to provide their respective services in a safe, secure and continuous manner. Within controlled airspace, U-space airspace is designated by the Member States and is dynamically managed by the ANSP. The safety of operations is guaranteed by the fact that manned and unmanned traffic will not mix with each other as they are dynamically segregated since both ANS and U-space services are not provided at the same time in the same volume of airspace.

In the short term, it is not considered that USSPs would provide ATC-like service in controlled airspace. If USSPs would provide ATC-like services within controlled airspace, they would need to meet the same certification requirements that ATS providers meet today and be designated as stipulated in the SES Regulation.

The Galileo Return Link Service (RLS) is a free global service available to Cospas-Sarsat RLS compatible beacons. This functionality offers a communication link that relays Return Link Messages (RLM) back to the originating beacon through the Galileo Navigation Signal in Space (I/NAV E1). This is part of the Galileo Search and Rescue (SAR) Service, which is continuously monitored by the GSA.

The Galileo RLS, which allows people in distress to receive automatic acknowledgement that their signal has been received, was declared operational at the 12th European Space Conference on January 21. 

The first performance evaluation of the Galileo Return Link Service (RLS) following its launch has revealed excellent service provision that exceeds set targets.  Galileo Return Link Service was available 100% of the time, above the target value of 95%. On average, the Galileo system took 37 seconds to deliver automatic acknowledgement to the beacon. This is significantly better than the target value of 15 minutes, which was achieved 99.61% of the time.

Sited in Denmark, the 600-square-kilometer Testbed in Aarhus for Precision Positioning and Autonomous Systems (TAPAS) covers both a densely populated city center and suburbs, a large industrial harbor and parts of Aarhus Bay. Aarhus is the second largest city in Denmark with a population of 350,000 people.

The TAPAS GNSS reference stations are equipped with the newest generation of GNSS receivers and antennas capable of tracking all available signals from the GPS, GLONASS, Galileo and BeiDou systems.

Based on RTK methodology, TAPAS is a sound ground-based testbed to support, test and validate technological developments with a need for fast, efficient, flexible and reliable precision positioning. It is designed as a geodetic innovation platform, with both physical and virtual networks providing positioning to the centimeter level (cubic centimeter).

Data from the TAPAS stations streams in real time to the Central Processing Facility (CPF) operated at a dedicated server at DTU Space in Lyngby, North of Copenhagen. The GNSS observations are processed using the GNSMART 2 software from Geo++, where corrections for network RTK positioning are estimated. The corrections are estimates for errors affecting the GNSS positioning, such as inaccuracies in satellite positions and clock drift parameters as well as ionospheric and tropospheric effects. The dense network of reference stations in TAPAS will assure that corrections for the atmospheric effects will be of very high quality.

After the field tests, it was concluded that the TAPAS testbed is able to provide correction data that makes it possible to perform GNSS-based positioning in real time in both static and dynamic mode with position uncertainties at the cm-level. In this way, TAPAS is able to aid research into feasible infrastructure for the technologies of tomorrow, such as autonomous driving or navigation of RPAS.

The Spanish Military Airworthiness Authority (Dirección General de Armamento y Material, DGAM) has acquired jamming devices able to inhibit both GNSS signals and control signals from the Remote Pilot Station to the Remote Piloted Aircraft, and to force its immediate landing.

The difference with respect to other jamming systems is the availability of unlimited number of inhibition profiles for any frequency ranging from 200MHz to 6GHz.

The GAUSS Project will enable not only safe, timely and efficient operations but also coordination among a higher number of RPAS in the air with the appropriate levels of security, as it will improve anti-jamming and anti-spoofing capabilities through a multi-frequency and multi-constellation approach and Galileo authentication operations.

The next February 12th a free webinar entitled “Automative-Grade GNSS + Inertial for Robust Navigation” will take place. Registration is open and free.

During the webinar, several sensor integrations will be covered regarding navigation in a full range of environments.

The members of the panel will guide the attendants through the intricacies of GNSS-inertial integration from three points:

• via sensor-agnostic self-contained software that performs tight coupling of carrier-phase GNSS with inertial measurements, a vehicle motion model with software-based multipath mitigation and without connecting to vehicle sensors;
• via tightly coupled GNSS, MEMS accelerometers and gyros, integrated in the GNSS module, from dual frequency with full RTK corrections and ambiguity resolution and a wheel-pulse connection (automotive dead reckoning);
• via a wheel-mounted inertial measurement unit providing high-rate (2 kHz) bias-free data, road-quality measurements and instantaneous wheel dynamics estimation.

Live testing of an autonomous car during last November provided positioning performances with safety margins, achieved by estimated protection levels designed into the positioning engine. In the European Safety Critical Applications Positioning Engine (ESCAPE) GNSS Engine (EGE), a real-time Precise Point Positioning (PPP) hybrid algorithm employs dual-frequency GPS and Galileo measurements, inertial sensors and PPP corrections from a web server over a cellular network.

A robust GPS + Galileo hybrid configuration for the positioning algorithm performs consistency checks in parallel for safety. This enhances the accuracy by integrating data from several vehicle sensors. EGE enables potential use of the Galileo signal authentication feature and tests provision of an integrity layer to assess the degree of confidence one can associate with the position information provided by the device.

Automotive intelligent cameras provide lateral distance measurements to road markings, combined with data showing position computed relative to lane-level accurate maps. This yields an accurate position relative to the map and enables estimation of the associated integrity Protection Levels (PLs), computed for multiple-target integrity risks (IRs).

The EGE was integrated in an autonomous car for driving tests in July 2019 at the University of Technology of Compiègne (UTC) in France. The car also carried a high-grade trajectory reference system (GNSS+high-grade IMU); its post-processed centimeter-error solution served as a truth reference to assess EGE performance.

The EGE (European Safety Critical Applications Positioning Engine GNSS Engine) provides a hybrid solution with an integrity layer, making the most of all sensors that should be present in autonomous vehicles and it creates a new paradigm of safety-oriented navigation technology on the road.

EGNSS4RPAS project, funded by the European Commission, has deployed recently dedicated flight trials to show how Galileo and EGNOS are able to commit to a safer and more efficient future of U-Space.

Some field trials took place at the ATLAS drone test facility in Villacarrillo, Spain involving a fixed-wing RPA and two multirotor RPAs. One trial took place in the urban environment of Villacarrillo using the multirotor RPA. This last operation was the first one in an urban environment ever approved by the national civil aviation authority AESA, and one of the few examples of real urban operations in Europe.

In all these experimental test operations, the RPAs were equipped with a multi-constellation and multi-frequency receiver which was used to compute the EGNSS solutions and the reference trajectory using Precise Point Positioning. Moreover, multi-constellation and multi-frequency antennas were also installed.

In open visibility conditions, the results clearly show that the use of Galileo in dual constellation with GPS significantly improves accuracy compared to GPS-only for both the horizontal and vertical dimension. The introduction of EGNOS significantly enhances the GPS-only accuracy.

The urban scenario posed several challenges to the reception of GNSS signals. Despite having fewer satellites available, the Galileo-only solution still provides significantly better performances than the GPS-only solution.

Eventually, these flight trials showed how European GNSS solutions are a pivotal element for the safety and efficiency of drone operations even in cities. These operations have demonstrated, again, the added value of EGNSS for drones and support the uptake of EGNSS-based standards in the RPAS community.

European GNSS (Galileo and EGNOS) can provide a significant support in order to effectively manage the response to an emergency or a disaster.

During distress events where the management of the consequences is critical, it is mandatory to have access to precise and updated information. GNSS makes a significant contribution during the mitigation phase of disaster management, supporting GNSS monitoring and early warning systems for disasters such as landslides or tsunamis. 

Regarding the integration of GNSS in RPAS for Search and Rescue, the MOBNET project is designing a system to locate isolated victims in the event of natural or man-made disasters. The system also can help first responder services to find lost people in the mountains.

MOBNET Project

The MOBNET solution takes advantage of the ubiquity of mobile phones and the cost and performance gains of using drones in search and rescue operations, while leveraging the high-quality timing synchronization capabilities provided by Galileo. Taking advantage of these features, MOBNET uses digital cellular technologies to detect the presence of people, by locating their mobiles, and help rescuers in their search.

Thales Alenia Space has been awarded a grant under the European GNSS Agency’s (GSA) Fundamental Elements funding mechanism for the development of the GIANO (Galileo-based TIming Receiver for CriticAl INfrastructure Robustness) receiver, which aims to make critical infrastructure more robust against interference, jamming and spoofing.

The GIANO receiver will leverage Galileo and EGNOS-driven innovation to improve the resilience of the receiver against interference, jamming and spoofing and increase the accuracy and reliability of the time transfer service.

The timing platform prototype to be developed and validated will integrate all the latest innovative technologies, including professional products from Thales Alenia Space, paving the way for future Galileo-based timing receivers that offer improved resilience and accuracy at a reasonable cost.

The project will also benefit from the support of the European Commission’s in-house science service – the Joint Research Centre (JRC) and the Italian National Metrology Institute (INRIM), which will make available its test facilities for verification activities on the developed equipment.

European GNSS, EGNOS and Galileo, provides significant added value to drone navigation, positioning and related applications, and the use of their differentiators will be instrumental in opening up new business opportunities.

RPAS are becoming the 3rd GNSS market segment for device shipments according to the last GSA market report. Drones generally integrate GNSS solutions in an effort to navigate efficiently and safely.

Within this context, there is a Call for Proposals recently opened under the European GNSS Agency’s (GSA) Fundamental Elements funding mechanism. This Call for Proposals is targeting the development of a drone-borne low-cost double-frequency Galileo multi-constellation receiver, integrated with INS (inertial navigation system) and other sensors. The technology should be at a sufficient level of maturity (technology readiness level 7).

Fundamental Elements call, at a Glance :

• Title: Development of a drone-borne double frequency Galileo receiver     
• Budget: €1,500,000
• Indicative number of projects: up to 2 projects
• Deadline for applications: 2 March 2020  

The call aims at delivery of a robust navigation solution, including integrity requirements for operations, that leverages Galileo differentiators such as OS Authentication and High Accuracy. The solution should be validated in a representative environment for the target operations. This includes conducting flight tests and analysing the performances obtained from a Galileo-only constellation and comparing these with those coming from multi-constellation mode.

Nowadays, GALILEO is a potential driver for the future navigation of autonomous vehicles.

The last November 27th, demonstrations of autonomous vehicles took place at the University of Technology of Compiègne, France. These live demonstrations involved for the first time Gelileo-enabled autonomous vehicles made in the EU.

Assisting participants to the event had the unique opportunity to ride in an autonomous vehicle fitted with a GALILEO-enabled ESCAPE GNSS engine (EGE).

The EGE is an innovative positioning engine that leverages the Galileo signals and services to provide a core positioning component in autonomous vehicles. It was designed and prototyped by the ESCAPE project, funded under the European GNSS Agency’s (GSA) Fundamental Elements programme.

The last November 28th, several test cases related to the SAFEDRONE project took place at the ATLAS Flight Test Center in Villacarrilo, Jaén.

Demonstrations were aimed to show the latest state of the art technologies related to U-space and the integration of drones into the airspace. The test cases involved large number of drones and general aviation aircrafts during the Open Day.

The main goal was to integrate general aviation aircrafts into U-space. Moreover advanced technologies related to U3 functionalities, like automated Detect&Avoid functionalities and operating a group of drones by a single pilot, were shown.

On the other hand, contigency situations were taken into account, such as geo-fencing breach and dynamic creation of no-fly zones.

CATEC (Advanced center of aerospace technologies) is sponsoring a new european project SAFEDRONE. It will tackle one of the major field trials in Europe, in Jaén.

The trials will involve drones and conventional aircrafts sharing the same airspace at very low level (VLL) up to 120 meters of height.

Through H2020 and SESAR JU, this initiative aims to facilitate the incursion of drone in cities and countryside surroundings in order to provide many services during the next decade.

All the flight tests will take place in Villacarrillo, Jaén. The trials will involve up to 8 different air vehicles flying at the same time in the same airspace. Concerning the RPAS, some operations will be performed beyond the visual line of sight, reproducing the delivery of medical items, generation of maps and control of territory use.

A consortium formed by GMV, VVA and FADA-Catec has assesed the Galileo and EGNOS features and services in the UAS sector for Air Traffic Management and other different applications.

The Egnss4RPAS project has deployed several test trials for unmanned aircrafts under the European Commission order to show the usefulness and aplicability of Galileo and Egnos services for UAS operations. The trials have proved that Galileo offers a better response compared to the GPS systems, as well as the corrections provided by EGNOS to enhance the positioning provided by GPS, showing precission errors below 1 meter.

The trials have showed without a doubt that when Galileo and EGNOS technologies are used together, the performances are very rebust.

The GSA is co-financing the SKYOPENER project, which aims for more civil RPAS aplications taking benefits from GNSS and EGNOS.

The growing demand of larger range RPAS missions cannot be satisfied due to the restrictions for beyond visual line of sight operations. Skyopener seeks to change this. The project is developing activities in order to reduce risks related to RPAS allowing ANSPs to manage low-level operations. In order to do this, Galileo and EGNOS will play a major role.

One test trial demonstrated that the use of GPS and Galileo under different frequency combinations provides a better availability, precission and robustness against against jamming.

The last 16th of September, several trials for using the Galileo Return Link Service (RLS) were performed in Madrid. This is a particular Emergency Locator Transmitter (ELT) for Distress Tracking (ELT-DT).

This service can be activated automatically should certain situations on board the aircraft take place and it can also be activated and deactivated remotely; so its functionality does not depend on the crew, and the position information can be later sent to rescue centers such as COSPAS-SARSAT.

The concept of using the ELT-DT with remote activation and subsequent deactivation emerged within an EUROCAE group in 2018. Several field trials were planned and a series of flight tests took place in Madrid in September. These trials consisted in activation tests with subsequent remote deactivations using radiobeacons.

With European GNSS providing the positioning accuracy that drones need to operate safely, more and more drone-based applications are hitting the market. The GSA highlighted a number of these innovative services during the Mobile World Congress in Barcelona.

The integration of EGNOS and Galileo into drone and UAV technology enhances positioning and opens the door to a wide range of new applications and services. In fact, according to the latest edition of the European GNSS Agency’s (GSA) Market Report, by 2025 the installed base of GNSS devices in drones will reach 70 million – more than twice the sum of other professional market segments combined. But with this growing market comes growing concerns about how to ensure the safe operation of drones.

The GAUSS project, a GSA initiative coordinated by everis Aerospace, Defense, and Security (everis ADS), recently organised a workshop at the University of Cranfield (United Kingdom) to analyse the benefits of Galileo and EGNOS in the context of operations involving unmanned systems (UAS) and their air traffic management (in Europe, U-Space). 

Together with the celebration of this workshop, another important milestone of the project was the signing of the EU U-space demonstrator network manifesto during the launch event on October 19th in Antwerp. This network, supported by the EC, EASA, SESAR JU, and Eurocontrol will become a forum to share knowledge on how to keep drone operations safe, secure, and green. It focuses specifically on relevant projects that, with a clear business case, build on mature technologies, but need some further operational and regulatory demonstrations before starting commercial operations.

Drones Crunch

The added value of EGNSS (Galileo and EGNOS) for drones was the focus of a special session organised by the European GNSS Agency (GSA) at this year’s World ATM Congress in Madrid on 12 March, at which representatives from several projects spoke about how they are benefitting from the European space programme.

The GAUSS GSA-H2020 project was represented by Adrián Jiménez González from Everis Aerospace & Defence, which is chairing the new EUROCAE subgroup on Multi GNSS for UAS. He said that the integration of Galileo and EGNOS into drone technology is mainly focused on safety and security, thanks to the increased integrity and accuracy that they provide. This is particularly relevant given the growing popularity of drones, Jiménez González said. “Due to their growing popularity and usage, in the near future we will see hundreds of drones sharing airspace, making the added value of EGNOS and Galileo, specifically improved manoeuvring, and accurate positioning, all the more relevant for public and airspace safety,” he said.
