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.
