目前的通信卫星大都运行在高３５８６０ｋｍ的地球静止轨道上，其优点是只需３颗卫星就基本能实现全球通信（南、北极除外），星座控制简单，不需要跟踪卫星及星间链路便可完成远距离通信．不足之处是静止轨道资源很紧张（按国际电信联盟规定，在３６０°的同此轨道上，每两颗 At present, most communications satellites are operating on the geostationary orbit at an altitude of 35,860 km. The advantage is that only three satellites can basically achieve global communications (except for the south and north poles), the constellation control is simple, and the satellite and the inter-satellite link do not need to be tracked To complete long-distance communications. The downside is that the geostationary orbit resource is very tense (as specified by the International Telecommunication Union, at the same orbit of 360 °, every two
