Estimating the term…
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.

A computer program product residing on a computer readable medium, the product comprising:
The product of claim 9, wherein the ADS-B signal includes at least one of latitude and longitude measurements, further including at least one of azimuth, estimation of signal frequency, amplitude of received signal and time of arrival.
The product of claim 9, wherein the standard transponder reply signals includes at least one of phase, amplitude, speed, direction, and altitude.
The product of claim 9, wherein the component for storing includes a look-up comparison table for comparing the ADS-B signals to the standard transponder reply signals.
