Gps Spoofing Simulator

Abstract: This paper, written at Safran Electronics & Defense as part of the author’s Master Thesis, is dedicated to the implementation of a GNSS alternate trajectory simulator for an aircraft GPS-aided Inertial Navigation System. First, the basic tenets of GPS-aided inertial navigation systems will be briefly reminded. The need for a GPS spoofing simulator will then be explained. The simulator architecture will be detailed, before showing the in-depth software implementation. Finally, the simulator performance will be ascertained to verify compliance with requirements.
