  • Patent number: 5402340
    Abstract: A terrain estimation system and procedure in which prior knowledge of terrain configuration is taken as a starting point in the estimation procedure. The gravity field of the earth is sensed by a gradiometer which measures the gravity gradient as the gradiometer is transported by a moving platform past the earth's surface to obtain data of the topology of the earth's surface and of the geology of the terrain including subterranean oil and iron deposits. Optimal filter means, operative in response to a statistical model of terrain and residual geology predict values of gravity gradient to be sensed by said gradiometer at successive locations along a path of travel. Comparison is made between measured and predicted values of gravity gradient to update terrain altitude data by nulling a difference between measured values and predicted values of gravity gradient.

  • Patent number: 5339684
    Abstract: An autonomous covert Inertial Navigation System uniquely suited for underwater applications wherein Schuler and siderial errors are bounded without external navigation aids or active instrumentation of ground speed is achieved by integrating a conventional Inertial Navigation System with a gravity gradiometer capable of measuring gravity field components independently of platform accelerations.
