摘要
从惯性导航误差方程着手,推导出了地面坐标系下的组合导航算法状态方程和量测方程,并给出了Kalman滤波的计算方程,通过仿真验证了组合导航算法的滤波性能。
A new method of GPS/SINS integrated navigation in ground coordinate is introduced. First inertial navigation error equations in ground coordinate are built up. On the base, the state equation and measure equation for intgerated navigation are derived out. Finally, the performance of navigation filer is tested by simulation.
