为了研究海况与航母机动方式对舰载机捷联惯导快速传递对准的影响，以姿态误差角为研究对象，建立了惯导系统的比力方程和姿态微分方程。从误差传播机理出发，详细推导了速度匹配和速度加姿态匹配的误差模型，然后用卡尔曼滤波算法进行仿真分析。仿真结果表明，航母有一定摇摆幅度更有利于舰载机进行速度匹配或速度加姿态匹配；典型海况条件下，航母的机动方式对速度匹配传递对准方式影响较为明显。

In order to study the Way hoW the sea conditions and the carrier mobility affect on carri—er—based aircraft SINSˊrapid transfer alignment, using the attitude error angle as research object, a specific force equation and attitude differential equation of inertial navigation system are established. The error model of velocity matching and velocity plus attitude matching are deduced detailly based on error propagation mechanism. Then simulating and analyzing are carried out With Kalman filter algorithm. The simulation results shoW, a certain sWing amplitude is more conducive to aircraft, s velocity matching or velocity plus attitude matching. Under typical sea conditions, the velocity matching transfer alignment is affected more obviously by aircraft carrier, s line motion.
