Patent ID: 8682581

Claim:
A vehicle navigation method comprising: receiving, from one or more LEO satellites, RF signals at a navigation radio; obtaining satellite ephemerides for a corresponding LEO satellite; deriving one or more range observables for the corresponding LEO satellite from the RF signals; establishing an altitude pseudomeasurement for the navigation radio; establishing a heading pseudomeasurement for the navigation radio; receiving at the navigation radio at least one of vehicle speed data, acceleration data, angular rate data and rotational angle data generated by one or more sensors onboard a vehicle moving at high dynamics; and using a processor, computationally calculating a position, velocity and time solution (“navigation solution”) based on the one or more range observables; ephemerides for the corresponding LEO satellite; the altitude pseudomeasurement; the heading pseudomeasurement; one or more vehicle velocity pseudomeasurements orthogonal to the altitude pseudomeasurement; and the at least one of vehicle speed data, acceleration data, angular rate data and rotational angle data.
