A method of supporting flight operations of aircraft includes accessing a data stream of geographic positions of aircraft on respective flights. The geographic positions are determined using a satellite navigation system and obtained from automatic dependent surveillance broadcast (ADS-B) position reports, or estimated independent of the ADS-B position reports. The geographic positions are tracked to determine a number of the respective flights for which the geographic positions change from being obtained from the ADS-B position reports, to being estimated independent of the ADS-B position reports. The method includes determining an outage in which the satellite navigation system is unavailable to the aircraft, based on the number of the respective flights for which the geographic positions change from the ADS-B position reports to estimated independent of the ADS-B position reports, and based on a threshold. And an outage notification is generated that is output to alert users of the outage.
