| 摘 要： | GPS绝对定位的精度取决于观测量的精度和所测卫星在空间的几何分布；相对定位组成GPS观测网时，需获得高质量的GPS网基线向量。由此可见GPS网观测方案的优化设计，对目前的工作有十分重要的意义。文章通过分析起始点坐标、网形的四项评定指标、卫星空间的几何分布在GPS观测中的影响，提出了观测方案优化设计的基本思想——布网基准的优化、布网图形的优化、最佳观测时段的选择。

| Abstract: | The accuracy of absolute GPS positioning depends on the accuracy of observation and the special distribution geometry.It needs high qualified baseline vectors of GPS network when the GPS observation network consists of relative positioning.Thus,the optional design of network observation scheme is of great significance.By analyzing the coordinate of the started point,the four elevation indexes of netting figure,and the impact of special distribution geometry of satellites on the process of GPS observation,the paper puts forward the basic idea for optional design of the observation scheme—optimizing the netting basic standard optimizing the netting figure,and choosing the best observing period. |
