Device, system and methods using angle of arrival measurements for ads-b authentication and navigation

Abstract

The present disclosure is directed to a receiver for Automatic Dependent Surveillance Broadcast (ADS-B) verification of a target aircraft including a first input for receiving flight tracking information from a target aircraft that indicates positional information of the target aircraft. The receiver further includes a second input for receiving positional and heading information indicating the location and orientation of a multi-element array antenna configured to be attached to the receiver, and a processing module that generates a measured bearing derived from angle of arrival data, and an expected bearing of the target aircraft derived from the indicated positional information of the target aircraft and the positional and heading information defining the receiver location and orientation. A comparator compares the expected bearing to the measured bearing and verifies the ADS-B flight tracking information of the target aircraft and outputs an indication of authenticity based on the verification.
