摘　　要：本文针对舰载弹用惯性系统的特点，利用舰上已有的惯性基准，在进行快速初始对准的同时，对惯性系统的陀螺误差进行估计和补偿，以提高陀螺的精度，克服逐次启动误差，满足导弹导航的精度要求。通过对系统的分析和仿真，论证了方案的可行性及有效性。This paper presents a method that can be used to estimate and compensate the gyroscope's errors of shipborne missile navigation system.According to the characteristics of the system and using the inertial criterion that already exits on the ship, it estimates and compensates the gyro errors at the same time of fast initial alignment to overcome the errors of each startup,improve the measuring accuracy of gyroscope, and meet the demands of navigation accuracy.By analysis and simulation,the paper proves the feasibility and validity of the method.
