Abstract

This invention relates to a system for verifying navigation integrity using GNSS truth vectors and non-terrestrial communication networks. The system comprises: a GNSS receiver receiving satellite signals to calculate navigation results; an integrity assessment module receiving the navigation results to calculate an integrity index; a truth vector generation module receiving the integrity index to generate navigation truth vector information; a communication interface transmitting the navigation truth vector information via a communication network; and a verification server receiving the navigation truth vector information to calculate a navigation reliability score.
