摘要
给出旋转式捷联惯导系统的误差方程。分析得到在旋转的条件下,系统主要误差源(即陀螺常值漂移,加速度计零位偏差)对导航参数输出的影响。通过数字仿真验证了理论分析的正确性,为旋转式捷联惯导系统的工程应用提供了理论基础。
The error equation of rotating strapdown inertial navigation system(SINS) is introduced.The affection of system's main error fountain(constant drift of gyro and zero bias of accelerometer) under rotating condition for the system is analyzed.Validity of theoretical analysis is validated via simulation,and that provides theory foundation for rotating strapdown inertial navigation system on actual experiment and application.
