摘　　要：舰载子惯导系统在海上应急启动时需要利用主惯导的信息进行传递对准,以达到快速、高精度启动的目的。同时必须对惯性器件的某些误差进行标定和补偿,以满足舰载惯导系统需要长时间高精度导航的要求。文中对平台式惯导系统采用速度加姿态匹配传递对准方法进行了研究,建立了基于Kalman滤波器的传递对准滤波方程,并在实际系统中对所设计的方案进行了静态和跑车试验,验证了方案的正确性和工程应用的可行性。Shipbome sub-INS（inertial navigation system） must use the information of main-iNS to implement transfer alignment in order to improve alignment precision and response time, and it must also calibrate the errors of inertial instruments to meet the long-time navigation requirements. The paper studied the principle of ＂velocity ＋ attitude＂ matching method for shipboard platform INS transfer alignment, and designed the transfer alignment filter based on Kalman filter. In order to validate the effect of the velocity plus attitude matching algorithm, the captive test and dynamic test were made in the system. The test results show that the present method satisfies the system performance.
