摘　　要：随着软件无线电的发展,软件定义卫星、软件定义卫星链路等思想在卫星通信系统设计中获得了越来越多的关注。为充分利用通信卫星的硬件资源,需要对卫星软件在轨重构系统技术进行深入而全面的研究。目前,针对卫星软件在轨重构方法的研究主要集中在通过卫星测控链路对星上个别软件进行更新,该研究思路未能从系统的角度出发考虑问题,因此设计的重构方法效率较低、可靠性不高。提出的利用星地高速馈电链路传输重构信息,通过星上多级数据缓存、存储,以及数据的集中式管控处理、分级下发。从系统的角度考虑软件定义卫星设计及星上软件的在轨重构,以期提高卫星系统运行的可靠性。该软件重构设计方法已经在某中轨卫星研制过程中得到了应用,取得了良好的效果。With the development of software radio,the ideas of software defining satellite and software defining satellite link have been paid more and more attention in the design of satellite communication system.In order to make full use of the hardware resources of communication satellites,in-depth and comprehensive research on satellite software in orbit reconfigure system technology is needed.At present,the research on on orbit reconstruction methods of satellite software mainly focuses on updating individual software on the satellite through satellite measurement and control.The research idea fails to consider the problem from the perspective of system,so the reconstruction method is inefficient and unreliable.A method of transmitting software reconfiguration information using satellite ground high-speed feeder link is proposed,storage through on-board multi-level data cache,and centralized control,processing and distribution of data.From the perspective of system,consider the design of software definition satellite and the on orbit reconfiguration of onboard software to improve the reliability of satellite system operation.The software reconfiguration design method has been applied in the development of a medium orbit satellite,and good results have been achieved.
