摘　　要：分析JTIDS相对导航定位原理及其误差特性,研究导航源时间质量、位置质量及导航源与用户几何位置关系即几何精度因子(GDOP)对定位精度影响。在导航源时间质量、位置质量一定情况下,仿真分析GDOP值,提出基于GDOP值的导航源选择原则,以供相关人士参考。This paper analyzed the JTIDS relative navigation positioning principle and its error characteristics,studied the navigation source time quality,location quality,navigation source position geometric relationships(GDOP)and the effect of navigation location accuracy.Under the navigation source time quality and location quality of certain value,the GDOP value is simulated and analyzed,and a method of source choice based on GDOP is presented.

关 键 词：JTIDS 几何精度因子 导航源选择
