| 摘 要： | 为达到伪卫星在任一时间、地点都能对目标进行精确可靠定位,对影响定位精度的关键技术—组网布局进行讨论。分析伪卫星及伪卫星定位系统的基本概念,探讨影响组网布局的3个因素：伪卫星定位系统的定位原理、伪卫星的＂视距＂范围和几何衰减因子。结果表明,几何精度因子GDOP与被观测伪卫星所构成的四面体体积成反比。

| Abstract: | In order to achieve pseudo-satellites at any time and place can be accurate and reliable positioning of the target,this paper discusses one of the key techniques affecting the accuracy of positioning-the research on configuration.It analyzes the basic concept of pseudo-satellite and pseudo-satellite positioning system,discusses three elements which affect the configuration: the principle of positioning,line of sight range,the dilution of precision(GDOP).The results show that GDOP is inversely proportional to the tetrahedron volume posed by the observed pseudo-satellites. |
