Validation tests of remote activation of Galileo radio beacons

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.
