摘要
在多颗卫星轨道的设计过程中,经常要考虑卫星对地球的覆盖情况。本文针对多颗卫星在某一时刻是否对地球进行了全球覆盖进行了探讨,并给出了一种简单的判定方法及其对应的算法,同时对这一方法进一步推广为判定是否多颗卫星同时对地球进行了N次覆盖。
The situation of coverage has to be considered in the design process of satellite orbit.This paper probes whether the whole earth is covered with satellite net at a special time.In accordance with this problem,a simple criterion and its corresponding algorithm are given.At the same time,the method is deduced to the problem:whether the whole earth is covered N times with the satellites.This paper is useful to the satellite net designing.
