摘　　要：本文根据捷联惯导系统的基本方程建立了动基座下的姿态误差方程、速度误差方程和位置误差方程,并得到动基座的误差传播方程。利用MATLAB对载体在匀速直线运动和三轴摇摆状态下的系统误差进行仿真,并得出了系统误差曲线,进而结合误差传播方程及方块图从理论上分析了动基座下捷联惯导系统误差特性。According to the basic equations of strapdown inertial measurement system, this paper established on moving base of attitude error equation, velocity error equation and the position error equations, and get the error propagation equations of moving base. Using matlab to simulate the system error of a vector in uniform motion in a straight line and the three axis swing state, and get the system error curve, and then combined with the error propagation model and block diagram are analyzed based on the theory of strapdown inertial measurement system error characteristics.
