Wen Sitan points out, besides the error that appears on the weekend, gu ge can judge a mistake rarely.

温斯坦指出，除了周末出现的失误外，谷歌很少会判断错误。

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。

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.

试验结果表明，当传感器噪声的均方根小于10米时，TERCOM算法可以获得大于90%的 匹配概率，SITAN算法也可以达到60~70米的CEP圆概率 误差。
