the result shows that when the mean root square of sensor noise is less than 10m, tercom algorithm can achieve matching probability of 90%, while the cep of sitan is 60~70 meters.
simulation results show that modified sitan algorithm is more reasonable and effective in theory than before one. meanwhile, the positioning accuracy is greatly improved.
计算机仿真结果表明,改进的sitan算法在理论上更加合理有效,定位精度更能够满足要求。
meanwhile, in this paper we've designed an integrated navigation information management system, based on sins, gps and sitan navigation system for a certain style of uav.
