Addressing GNSS Spoofing Threats with Honeywell GNSS Aided Inertial Systems

The Jamming and Spoofing events are nowadays more and more present over the whole globe and can significantly impact the avionics and navigation systems in many ways. It is necessary to raise the awareness of these challenges and provide the reliable protection to the avionics systems against the threats. This paper addresses development, implementation and mainly testing of the newly developed advanced spoofing monitoring function, which is intended to be used on GNSS Aided Inertial Systems as e.g., GPAHRS.
