Abstract
Methods and systems to process and assure integrity of radar measurements, detect the effects of GNSS jamming and/or spoofing events, identify GNSS measurements affected by the GNSS jamming and/or spoofing events, and assure the integrity of the GNSS measurements unaffected by jamming and/or spoofing events in a vehicle navigation system are disclosed. The methods are implemented to integrate inertial measurements, GNSS measurements, and radar measurements for the vehicle, and apply solution separation techniques to all of the measurements. The solution separation techniques use a main filter for hybridization of the inertial measurements, the GNSS measurements, and the radar measurements, with additional sub-solution filters and sub-sub-solution filters that use combinations of these measurements. This provides common processing of the GNSS and radar sensors in a single hybridization and solution separation framework.
