摘　　要：为解决舰载主惯导与机载子惯导之间大失准角问题,同时满足对准快速性的需求,提出了从舰载机进入弹射位置开始,到舰载机飞离甲板时间内,基于虚拟惯导(VINS),综合利用舰载主惯导信息、跑道航向信息以及激光多普勒测速仪(LDV)信息,利用速度匹配方法实现舰/机惯导传递对准的方法,并建立了传递对准误差模型。该模型利用舰艇坐标系与跑道坐标系之间的方向余弦矩阵,将舰载坐标系与机载坐标系之间的大失准角问题,转化为机载坐标系与跑道坐标系之间的小方位失准角问题。考虑弹射过程舰艇及舰载机的运动模型,利用数学仿真对传递对准误差模型进行了验证,并与UKF滤波方法进行了对比。仿真结果表明,该方法可以在8 s内实现舰/机惯导的传递对准,对准性能与UKF滤波方法相当,且对准过程不需要舰艇进行任何机动运动。To solve the large azimuth misalignment angle problem between MINS and SINS, and shorten the transfer alignment time, a take-off alignment method of the carrier-based aircraft is put forward, and the linearization error model of transfer alignment is built in this paper. This method synthetically uses the velocity of MINS, the azimuth of the rtmway and the velocity of Doppler velocimeter to transfer the lager azimuth misalignment angle problem between MINS and SINS into small azimuth misalignment angle problem between aircraft coordinate and runway coordinate. Considering the motion models of the carrier-based aircraft and the aircraft carrier, the simulation is carried out by comparing with UKF. The results show that the transfer alignment can be implemented within 8 s, and the performance is equivalent to that of UKF, and there is no need to carry out any maneuver for aircraft carrier.
