卫星星历及广州气象卫星地面站相关数据分析

Analysis of satellite ephemeris and associated data of Guangzhou meteorological satellite ground station

本文简要介绍了开普勒三定律以及确定人造地球卫星在空间瞬时位置的6个轨道参数;详细描述了由美国Celestrak发明并创立的卫星星历即两行轨道数据(two-line orbital element)的格式和含义;分析了广州气象卫星地面站接收任务中的部分卫星星历,并从中找出相关性。指出要准确跟踪太阳同步卫星,必须使用最新的卫星星历。

This paper briefly introduces the three laws of Kepler and definites six orbit parameters of man-made earth satellite in instantaneous spatial location. The format and meaning of satellite ephemeris,known as two-line orbital element, invented by United State Celestrak are described in detail. Partial satellite ephemeris of Guangzhou meteorological satellite ground station during receiving task is analysed, and its correlation is found out. To accurate traek sun synchronous satellite, up-todata satellite ephemeris must be used.
