Abstract
Aimed at the low precision and high cost of on-orbit calibrating accelerometer scale factor,as well as the auxiliary requirement and the difficulty in engineering implementation,a method of on-orbit calibrating accelerometer scale factor based on the lever arm effect was presented.As long as the knob mechanism of the inertial assembly rotates uniformly at the given speed,the scale factor of the accelerometer can be calculated according to the output of the gyroscope and the accelerometer in the inertial assembly.The calibration principle was analyzed,the calibration model was built and the separation algorithm of the error coefficient was derived.The effect of this method was verified by the ground test.关键词
