The result of simulation indicates that the positioning (accuracy) can be determined by the resolution of reference map, also indicates that the circle of equal probability (CEP) is 0.7 times of the resolution with a middling INS in this algorithm.

• 仿真结果表明；在可匹配区其定位精度与地图格网间距相关；圆概率误差(CEP)可以达到地图网格间距的0 7倍.
