一种区域性中轨道卫星移动通信星座

A MEO Satellite Constellation for Regional Mobile Communication

提出一种中轨道卫星移动通信星座 ,它可以提供包括中国在内的亚洲及太平洋地区的通信服务 ,最小观测仰角按 30°设计。该星座由 6颗周期为 12 h、倾角为 2 8.5°的圆轨道卫星组成 ,轨道高度为 2 0 183km,6颗卫星均布在同一条地面轨迹上。

A MEO satellite constellation for Asian and pacific regional mobile communication is suggested.The minimum elevation of 30 degree is guaranteed for the ground users.The constellation consists of six satellites placed in six orbital planes which are even distributed along the equator.The circular orbits have same inclinations of 28 5 degrees and same periods of 12 hours with the altitude of 20183km.All six satellites will move on the same ground track,but even separated.
