  • Method and system for terrain aided navigation
    Patent number: 6512976
    Abstract: A method and system for terrain aided navigation which provide more precise and more accurate position, velocity, altitude, and attitude for an air vehicle. The present method is a continuous, active, all-weather, day/night, self-contained vehicle system used for terminal and en route navigation. The present method utilizes on-vehicle sensing elements which require no external stimulation, eliminating dependence on external ground and space-based navigation aides. The present method also provides a drift-free solution. The present method is more difficult to detect (sense) and more difficult to disrupt.
