Precise self-calibration method for shaking base of platform type gravimeter

The invention belongs to an inertial device calibration technology, specifically to a self-calibration method, in particular to a precise self-calibration method for a shaking base of a platform typegravimeter. The method includes: determining a conversion matrix of a P system relative to a G system at the starting moment of each position according to an addition table and resolver data, calculating a position error and an attitude matrix at two positions, calculating an uncompensated platform drift on a geological system at each position, an uncompensated accelerometer error on a Yg axis ateach position, a misalignment angle of the platform relative to a horizontal plane, and a speed component which is ignored when t is equal to 0, correcting platform drifting and meter adding parameters, correcting the speed component when t is equal to 0 at each position, and ending iteration until conditions are met. Calibration errors caused by carrier shaking are effectively avoided, high disturbance rejection capacity
