Abstract
A method for group travel and group communications, wherein the group travel parameters and group communications are combined for verifying and validating ADS-B data on aircraft. The full connectivity within a navigating group of aircraft allows all the group members to communicate spatial/temporal observations and collaborate in group protocols, e.g., majority voting protocol, which can determine if a received ADS-B message is corrupted or from a false target aircraft. Well-established distributed protocols based on group communications and majority voting exist for (1) detecting compromised members, i.e., false target aircraft, and (2) verifying message integrity, i.e., ADS-B data, given a minority fraction of members are compromised/colluding. Such protocols can be based on IP multicast communications over the IP networking data links available on the aircraft. Also disclosed is a method for verification and validation of position indicator message data on aircraft.
