Patent ID: 7429950

Claim:
A system for measuring and monitoring performance metrics of a non-ADS-B tracking system and generating performance metrics for the non-ADS-B tracking system in terms of ADS-B equivalent performance metrics, the system comprising: a plurality of ground station receivers for receiving from a vehicle, signals including ADS-B signals, the plurality of ground station receivers comprising at ADS-B stations, and alternate tracking system stations; an ADS-B processor, coupled to at least a portion of the plurality of ground stations, for deriving aircraft-derived ADS-B metrics from the ADS-B signals; an alternate tracking system processor, coupled to at least a portion of the plurality of ground stations for receiving tracking data from the alternate tracking system stations, determining vehicle position from the tracking data to generate an alternate tracking system vehicle position, and generating metrics from the alternate tracking system vehicle position in equivalent ADS-B metrics formats; and a system processor for receiving ADS-B metrics from the ADS-B processor and alternate tracking system metrics from the alternate tracking system processor, the system processor performing at least one of selecting and fusing tracking data based upon the ADS-B and alternate tracking system metrics.
