| 摘 要： | 天链一号数据中继卫星在轨成功运行,标志着我国在天基信息传输领域的重大突破,今后发展方向是建设中继卫星组网系统,以满足数据中继不断增长的需求.分析表明:经度间距约为180°的地球静止轨道(GEO)双星组网系统,只需在我国本土设立控管站,利用地面高速光纤干线,双星就能对离地高度大于95km的航天器实现100%轨道覆盖的中继...

| Abstract: | The successful in-orbit operation of the China’s first data relay satellite Tianlian-1 makes breakthrough in the field of space-based information transfer.The reasonable next step for China is to establish a space network in order to fill the continuous growth of demands.Benefiting from the existing ground optical fiber infrastructure,a system of two GEO data relay satellites with about 180° longitude difference between them would be a suitable way in China’s condition.It need build the control earth stations only on the China’s territory and can offer 100% orbit coverage for LEO/MEO user spacecraft whose altitudes are higher than 95km.It has good technical heritage and broad prospect. |
