    Abstract: A system having components coupled to an aircraft and components remote from the aircraft processes radar-augmented data, transmits information between aircraft system components and/or remote system components, and dynamically determines locations and states of the aircraft, while the aircraft is in flight. Based on the locations and states of the aircraft, the system generates instructions for flight control of the aircraft toward a flight path appropriate to the locations of the aircraft, and can update flight control instructions as new data is received and processed.

    Abstract: An aircraft receives pseudorange input from a plurality of satellites of an augmentation system. Each pseudorange input includes a precise position solution and error data. The aircraft receives a high frequency measurement from an inertial navigation system. The aircraft applies the precise position solution, error data, and high frequency measurement to a set of parallel Schmidt extended Kalman filters to produce a corrected position solution and integrity data. The aircraft applies the integrity data to a receiver autonomous integrity monitoring system to produce a protection level for the corrected position solution. The aircraft performs an aircraft operation using the corrected position solution and protection level.
