According to the U.S. National Telecommunications and Information Administration:
Airborne Doppler navigation systems are installed in aircraft (helicopters, as well as certain airplanes) and used for specialized applications such as continuous determination of ground speed and drift angle information of an aircraft with respect to the ground. The Radio Technical Commission for Aeronautics has developed a minimum operational performance standard for this equipment "DO-158 – Airborne Doppler Radar Navigation Equipment."
