  • Terrain correlation system
    Patent number: 6218980
    Abstract: A terrain correlation system for use in conjunction with an inertial navigation system of a vehicle is provided which can update position information and which is both independent of altitude and compatible with varying course paths. In the preferred embodiment, reference terrain altitude maps are converted to reference map transformation values. The reference map transformation values are used in conjunction with a terrain correlation process to establish vehicle position. The system also is able to select reference map scenes to the left, right, front or rear of present vehicle position so that curved travel paths can be updated in a manner similar to more conventional straight line vehicle paths.
