Dummy Topography Projection and the Aggregation of the Results in the Earth Synchronous Satellite Positioning System

  • 摘要: 基于地球同步卫星定位原理,分析了当利用数字化地形图提供测站高程时测站的多解和无解现象。利用观测方程给出了判断多解和无解的依据,提出了虚拟地形投影方法,获得了“亚稳定”收敛点的定位解子集π2

     

    Abstract: According to the Earth synchronous satellite positioning principle, multi-results and non-results are analyzed when the station height is given using DEM. By observation equations, the criterions of judging multi-results and non-results are obtained. Introducing the method of dummy topography projection, the subclass π_2 of positioning results belong to sub-steady convergence is gained.
