FAA, Nav Canada and Aireon Test Space-based ADS-B
Messages from the space-based system proved comparable to those from the ground-based system.

As part of a larger validation effort to test space-based automatic dependent surveillance-broadcast (ADS-B) technology, the FAA and Nav Canada successfully have flown tests in Bombardier aircraft to validate ADS-B signals captured by satellite, both agencies reported earlier this month. Nav Canada used a CRJ-200 (registry C-GNVC) with top- and bottom-mounted 125-watt ADS-B antennas, while the FAA employed a Global 5000 (registry N47) that was equipped with three Aireon payloads to receive data and top- and bottom-mounted fuselage antennas.
