Spire is a data and analytics company that collects data for earth from space, to help business and governments address previously insurmountable problems affecting everyone on the planet. Its constantly improving constellation of LEO satellites uses listening sensors to listen to the planet in real-time. New ICAO regulation as part of Annex 6 will soon require operators that operate outside of radar coverage to monitor their own aircraft with 15-minute tracking. The only way to do this is with space-based ADS-B tracking. In 2019 Spire's satellite constellation and ground station network will be fully capable of providing this service to operators.
