Embodiment Construction
[0042] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0043] Depend on figure 1 It can be known that a rotational accelerometer gravity gradiometer angular motion error compensation device of the present invention includes an angular motion detection module, a reference signal generation module, an angular motion error transfer coefficient detection module, an angular motion error compensation signal generation module, and a centrifugal gradient detection module. Compensation operation module, gravity gradiometer accelerometer signal processing module, gravity gradient signal recovery module.
[0044] Wherein the centrifugal gradient detection module outputs the centrifugal gradient excitation of the gravity gradiometer in the calibration mode, and has no output in the non-calibration mode.
[0045] The angular motion detection module provides the angular velocity and angular acceleration signals of the gravity...
