Abstract
A system and a method for estimating a position of a vehicle. The vehicle includes a gradiometer. The method includes calculating a gravity vector using a gravity spatial derivative generated by the gradiometer and a plurality of body velocities generated by a body velocity source, calculating a gravity potential based on the gravity vector, and estimating an inertial measurement unit (IMU)-based position using the gravity vector, a body acceleration, and a body attitude. The method includes estimating a gravity vector-based position using the gravity vector and estimating a gravity map-based position using the gravity potential and one or more gravitational maps. The method includes estimating the position of the vehicle based on the IMU-based position, the gravity vector-based position, and the gravity map-based position, and controlling at least one of the vehicle and a second vehicle based on the position of the vehicle.
