摘要

提出一种低轨通信星座与地球站连通规划方法。考虑低轨通信星座卫星数量较多，直接建立低轨通信星座与多个地球站的连通规划方法难度较大，依次建立单颗卫星与单个地球站连通规划方法、星座与单个地球站连通规划方法、卫星星座与多个地球站连通规划方法，前一规划方法是后一规划方法的基础，后一规划方法是前一规划方法的拓展，最终形成一种低轨通信星座与多个地球站的连通规划方法。典型的仿真算例表明，地球站与卫星星座连通的过程中，地球站到卫星的仰角不低于通信仰角下限；在地球站与卫星的单个连通段内，离轴角的变化趋势都是先变小后变大；地球站选择的连通卫星分别展现轨道面切换和一个轨道面内的卫星依次切换，都间接验证了连通规划策略的正确性。

Abstract

A connection planning method between LEO communication constellation and earth station was proposed.Considering the large number of LEO communication constellation satellites

it is diffi cult to directly establish the connection planning method between LEO communication constellation and multiple earth stations.The connection planning method between single satellite and single earth station

the connection planning method between satellite constellation and single earth station

the connection planning method between satellite constellation and multiple earth stations were established.The former planning method is the basis of the latter planning method

which is the expansion of the former planning method

and fi nally forms a connection planning method between LEO communication constellation and multiple earth stations.A typical simulation example showed that in the process of connecting between the earth station and the satellite constellation

the elevation from the earth station to the satellite was not lower than the lower limit of the communication elevation.In the single connecting section between the earth station and the satellite

the variation trend of off -axis angle decreases fi rst and then increases.The connected satellites selected by the earth station showed the orbital plane switching and the sequential switching of satellites in an orbital plane

which indirectly verifi ed the correctness of the connection planning strategy.
