First Claim
1. A non-transitory computer program product residing on a computer readable medium, and the medium being used by a processor to execute the program product the product comprising:
- a memory for storing associated bearing values;
a software for generating a traffic collision and avoidance system (TCAS) interrogation signals;
a software for receiving a reply to the interrogation signal; and
a software for determining bearing based upon the stored associated bearing values.

Abstract
System, method and computer program product for determining bearing using ADS-B and TCAS standard reply bearing estimates are disclosed. In one embodiment, a method for determining bearing based upon ADS-B signals includes receiving ADS-B signals and standard transponder reply signals. A first bearing estimate is based on the ADS-B signal. A second bearing estimate is based on the standard transponder reply signals. A database is developed according to the first and second bearing estimates via the ADS-B and standard transponder reply signals. In one embodiment, where ADS-B signals are unavailable, associated ADS-B signals associated with the standard transponder reply previously stored in the database are used to determine bearing.
