Original Abstract Submitted

An inertial coasting monitoring system comprises aiding sensors onboard a vehicle, including a GNSS receiver and at least one non-GNSS aiding sensor, and an inertial measurement unit (IMU) that produces inertial measurements for the vehicle. A navigation system is coupled to the aiding sensors and the IMU. The navigation system comprises a main navigation filter and an inertial navigation system (INS). The navigation filter receives aiding data from the aiding sensors including GNSS aided data, and the INS receives inertial data from the IMU. An onboard inertial coasting monitor communicates with the navigation system, and receives inertial data from the IMU and aiding data from at least one non-GNSS aiding sensor. The inertial coasting monitor comprises inertial coast sub-filters and communicates with the navigation filter. The inertial coasting monitor performs a position detection process and/or a velocity detection process to detect if there is a fault in the aiding data.
