摘　　要：针对单系统定位中存在的不足,主要对GPS、北斗以及两者的组合系统的最小可探测偏差进行仿真分析。仿真结果表明:GPS与北斗双系统组合定位导航存在明显的优势,最小可探测偏差相较于单系统而言要小,组合系统内部可靠性高于单系统。It is presented in this paper that the single system have shortcoming in the po-sitioning result ,the minimal detectable biases of the GPS 、COM PASS and the multi-system of the two positioning systems is simulated .The result of the simulation indicates that the superiority of the multi-system is higher than the single system ,the value of the minimal de-tectable is smaller than the value of the single system and the internal reliability of the multi-system is more reliable than the single system .

关 键 词：北斗 最小可探测偏差 可靠性
