GPS网形与GPS网质量的关系分析

Study on Relationship of Shapes and Quality of GPS Nerwork

基于GPS静态相对测量,基线数据处理采用双差观测值单基线解算的一般模式,讨论GPS网基线解算和3维无约束平差的公式,得出GPS网的质量与基线向量质量和GPS网结构有关,而与网形和点位无关,并通过实验数据,分析验证了这一观点,提出了一些有益的结论。

The paper is to analyze the relationship between shape and quality of GPS network which is based on static relative positio- ning model and uses double -difference observations and single -baseline model to resolve the baseline vectors. The result indicates that the quality of GPS network depends on the quality of baseline vectors and there is no business with the shape of network. Finally, some suggestions can promote the quality of a typical engineering survey network with GPS.
