Abstract
An airborne navigation system that uses Doppler information from an on-board weather radar to improve the system's accuracy and/or fault tolerance. The system can determine a drift angle and ground speed from Doppler information associated with radar returns from the Earth's surface. Alternatively, the system can be configured to determine heading angle using the drift angle and a track angle received from another sensor.
