| 摘 要： | 利用Matlab软件解算GPS历书信息，对GPS卫星星座进行预报仿真。给出了计算仿真的整体流程和部分主要实现代码，最后通过实际接收卫星数据的计算，得出了预报仿真结果。此方法既能直观理解星座运动分布，也能满足工程实践中快速捕获卫星的需求。

| Abstract: | The information of GPS almanac with MATLAB is calculated, and the GPS constellation is forecasted and simulated in this paper. We presented all the schematic diagrams of calculation and partial primary code. With received almanac information to calculate, we have gotten the simulated results. The results show an easy way to understand the movement of GPS constellation and provide a method to select constellation fast for position application. |
