摘要
从捷联惯性系统的误差源出发,根据系统的误差方程,通过理论分析和仿真,阐述了各惯性传感器误差和初始误差对系统的影响,并在几种动态环境下对系统的误差特性进行了仿真。结果表明:与静态误差特性相比,系统的误差特性发生了较大的变化。
The error source of Strap-down Inertial Navigation System(SINS) is presented. Based on the error state equation, the influence of initial error and each inertial sensor error on the system is studied through theoretic analysis and simulation. The error charateristics simulations were carried out under several dynamic environments, and the results show that the characteristics of system error changed greatly compared with that of the static error.
