摘要
根据本文的假设，分别计算了ＧＥＯ、ＭＥＯ和ＬＥＯ卫星移动通信系统各自需要的卫星ＥＩＲＰ和Ｇ／Ｔ，据此比较了各系统需要的空间系统总投资，得到了在区域卫星移动通信系统中采用ＧＥＯ最经济、在全球卫星移动通信系统中采用ＭＥＯ较经济的结论。
Based on the assumption,the required EIRPs and(G/T)s of different orbit height’s satellites were calculated respectively,then,the overall space system invest of each system was calculated and compared, the conclusions were:for regional mobile satellite communication system, GEO is the most economic;for the regional system,MEO is the relatively economic.
