Claim 11:
12. A method of enhancing an accuracy of a vehicle location determining system, the method comprising:
generating a profiled terrain using a digital active phased array radar that includes altitude information;
comparing the profiled terrain with terrain altitude information in a terrain database;
determining a profiled location solution when a match is found between the profiled terrain and terrain altitude information in the terrain database;
comparing the profiled location solution with at least a sensor location solution from a global navigation satellite system (GNSS) receiver;
determining if location errors are present in the sensor location solution from the GNSS receiver based on the comparison of the profiled location solution with the sensor location solution from the GNSS receiver; and
broadcasting determined location errors.
