在惯导系统中，如果加速度零位不准确便会影响到测量船精度的提高。船载情况下，船体晃动明显，惯导工作环境比较恶劣且时间长，因此加速度计会出现精度下降甚至无法正常工作的情况。因此在更换加速度计后，需要在静稳定的情况下对零位进行标定。论述了惯导原理，通过对船载惯导工作中的具体情况以及数据的分析，提出了在某些特殊的应急条件下，加速度计零位的动态标定方法。实验结果表明，该方法可靠性高，能够满足应急条件下加速度计的标定，标定的结果满足船载惯导系统需求。

There are many factors influencing the measurement accuracy of TT&C ship.In the inertial navigation system (INS),if the acceleration zero is inaccurate,the measurement precision of a ship would be affected.In marine environment,the ship often shakes seriously and INS works in poor environment for long hours. The accelerometer accuracy degrades and even does not work. In case of replacing the accelerometer,the ship is required to calibrate the accelerometer zero in static stability condition.Explanation of INS prin?ciple and analysis of the shipborne INS data and situation is provided. A method of dynamic calibration of accelerometer zero in emer?gency conditions is proposed.Experiment results show that the method provides high stability and meet emergency conditions accelerom?eter calibration.Calibration results satisfy the onboard INS requirements.
