为解决航天器惯性测量组合与过载相关的动态误差难以在地面精确标定的问题，提出并构建了一种基于正弦直线过载的惯性测量组合动态误差试验系统。利用该系统提供过载的正弦特性和直线往复运动的周期特性，结合惯性测量组合在正/负半周期内的脉冲输出，标定惯性测量组合动态误差。试验结果表明，采用该系统标定的惯性测量组合动态误差重复性、一致性好，是惯性测量组合动态误差的地面精确标定的一种有效手段。

Aiming at the difficulty of accurate calibration for inertial measure unit ( IMU) dynamic error on the ground , a new calibration method for IMU dynamic error based on sinusoidal linear ac-celeration experimentation system was proposed .An experimentation system which could supply si-nusoidal linear acceleration environment to meet the IMU test requirements was set up .By using the sinusoidal characteristic of acceleration supplied by the new system and period characteristic of linear reciprocate , combined with IMU output pulse in half positive and minus periods , IMU dynamic error was calibrated .The experiment results indicated that the IMU dynamic error calibrated by this meth-od had good repetition and consistency .So this method provides an effective tool for IMU dynamic error accurate calibration on the ground .
