摘要
对卡尔曼滤波地形辅助导航的发散原因作了分析，通过地形拟合误差的去相关法采用一种扩充状态变量的系统。
The divergence of terrain aided navigation by Kalman filter is analyzed. A kind of system with angmented state variable which is independent of terrain fitting error has been proposed. The experiment result shows that the system could decrease the occurrence of the divergence effectively.
