针对天基网络规模庞大、动态拓扑、链路较长的特点,提出了一种可以实现对地球全天时覆盖的多层星座组网模型,并分析了链路的通断情况。首先利用天文学卫星运动原理,结合卫星对地球覆盖的需求,提出了一种由5颗GEO卫星和9颗MEO卫星组成的多层星座网络模型;随后通过STK软件,对星座链路进行了分析,仿真结果证明了网络结构的可行性和稳定性。通过分析仿真结果,总结了卫星组网中需要考虑的影响因素,以期为建设符合我国国情的天空地一体化信息网络提供有益参考。
針對天基網絡規模龐大、動態拓撲、鏈路較長的特點,提齣瞭一種可以實現對地毬全天時覆蓋的多層星座組網模型,併分析瞭鏈路的通斷情況。首先利用天文學衛星運動原理,結閤衛星對地毬覆蓋的需求,提齣瞭一種由5顆GEO衛星和9顆MEO衛星組成的多層星座網絡模型;隨後通過STK軟件,對星座鏈路進行瞭分析,倣真結果證明瞭網絡結構的可行性和穩定性。通過分析倣真結果,總結瞭衛星組網中需要攷慮的影響因素,以期為建設符閤我國國情的天空地一體化信息網絡提供有益參攷。

According to the characteristic of space network with large scale,dynamic topology and long link,in this pa-per,a multilayer constellation network model that can be achieved to cover earth all day time is presented. The con-nectivity of inter-satellite chain is also analyzed. Firstly, the principle of satellite movement in astronomy is combined with the requirement of satellite coverage. A multi-layer model constellation with five GEO and nine MEO satellites had been planned. What was more, using the STK software, the chain between satellites is analyzed . The results proved the feasibility and stability of network structure. By analyzing the simulation results, the factors that need to be considered in satellite network are summarized,that provide a useful reference for the construction of the integrated in-formation network according with our country’s condition.
