Abstract
A method of validating ADS-B is described herein. The method includes receiving, from time synchronized vehicles, ADS-B data (identifier, horizontal position information, and altitude information for a first vehicle) with a timestamp (defining a time of reception of the ADS-B message). The method includes receiving, from each vehicle, a determined position at the time of reception of the ADS-B message. The method includes determining differences in time of arrival for the ADS-B message to each vehicle, extracting altitude information from the ADS-B data, and determining an estimated horizontal position of the first vehicle based on the differences in time of arrival, the determined positions received from each vehicle, and the extracted altitude information. The method includes determining whether the horizontal position information in the ADS-B message is valid based on a comparison of the estimated horizontal position of the first vehicle and the horizontal position information in the ADS-B message.
