摘　　要：根据Walker星座构型特点,提出了一种用较少数量服务卫星无须变轨为整个Walker星座进行服务的服务卫星轨道设计方法。以轨道面为单位,星座每个轨道面布置1颗服务卫星,服务卫星轨道位于星座轨道共面相交的椭圆轨道,每颗服务卫星无需变轨能与同一轨道面上的所有星座卫星交会。根据多星交会条件推导了服务卫星轨道要素的计算公式。通过算例分析,验证了Walker星座服务卫星轨道设计方法。According to the Walker constellation configuration features, a kind of servicing satellite orbital design method is proposed, which can use fewer servicing satellites providing services for the entire Walker constellation without orbit maneuver. For each orbital plane of the Walker constellation, a servicing satellite is arranged for rendezvous with all satellites on the same orbital plane without orbit maneuver. The servicing satellite orbit is elliptic, intersecting the constellation satellite orbit in the same plane. Based on those multi-satellites rendezvous conditions, the calculate expressions of the servicing satellite orbit elements are formulated. By analyzing examples, the Walker constellation servicing satellite orbit design method has been validated.
