Abstract
An ADS-B traffic filter to remove ADS-B positional messages or tracks with unstable ADS-B data or anomalies. The anomaly in ADS-B data can be caused by own ship ADS-B data processing and by errors in ADS-B OUT messages, such as positional outliers, ADS-B OUT parameters gaps, frozen data, walking track when stopped and other issues within ADS-B OUT messages. The ADS-B traffic filter of this disclosure may remove erroneous ADS-B targets from computation input delivered to a traffic collision warning systems in locations where high horizontal position accuracy is desirable such as ground operations. The filter may validate positions decoded from received ADS-B OUT messages, and data history of targets, to independent signal components from ADS-B broadcast (e.g., position and ground speed data), as well as compare the reported position with a reasonability bound provided by local runway or airport geometry data.
