1. A vehicle location accuracy enhancement system, the system comprising:
at least one location determining system configured to generate sensor location solutions;
at least one digital active phased array radar configured to generate a profiled terrain including terrain altitude information;
at least one memory to store at least a terrain database and operating instructions;
at least one controller in communication with the at least one location determining system, the at least one digital active phased array radar and the at least one memory, the at least one controller configured to implement the operating instructions in the memory to conduct profile matching between the generated profiled terrain from the at least one digital active phased array radar and terrain altitude profile information in the terrain database to determine profiled location solutions, the at least one controller further configured to at least augment the sensor location solutions from the at least one location determining system with the profiled location solutions to enhance accuracy of the sensor location solutions; and
wherein the at least one location determining system includes a global navigation satellite system (GNSS), the at least one controller is configured to determine location errors in the GNSS based on the profiled location solutions, the at least one controller further configured to broadcast the determined location errors.
