用户终端单星定位时定位精度问题的研究

Research on Positioning by Single Satellite in LEO Communication System

本文给出了一种满足一般要求的单星定位算法，并对卫星覆盖区域内的PDOP值进行了仿真，说明了高程方程的重要作用，并对高程误差引起的定位误差进行了分析。

Propose a arithmetic for user terminal positioning in the LEO communication system, research and simulate its PDOP; research the error caused by height error.
