GRAVITY GRADIOMETER AND METHOD FOR CALCULATING A GRAVITY TENSOR WITH INCREASED ACCURACY |
摘要 |
A method includes measuring an acceleration along an input axis (62a) of an accelerometer mounted to a gradiometer disc, the accelerometer having a coordinate axis that is parallel to a spin axis (Za) of the disc, and includes calculating a gravity tensor element as a function of the measured acceleration and a component of the measured acceleration caused by an acceleration along the coordinate axis. Consequently, this technique typically yields a more accurate calculation of the gravitational field by accounting for undesired accelerations picked up by accelerometers having input axes that are not parallel to the gradiometer disc.
