Low earth orbit satellite feed link switching method

The invention discloses a low earth orbit satellite feed link switching method, and belongs to the field of low earth orbit satellite communication. In order to solve the problems of data interruption and loss, large satellite-ground storage resources and large switching delay in the low-orbit satellite feed switching process, the problems of reliable transmission of satellite-ground feed link data and prolonging of effective communication duration are solved through a satellite configuration two sets of independent feed link loads and a satellite-ground cooperative routing layer switching method. The method can be applied to various low-orbit satellites and low-orbit satellite constellation systems, can ensure reliable interaction of satellite-ground data, and is especially suitable for autonomous operation after networking of the low-orbit satellites. 本发明公开了一种低轨卫星馈电链路切换方法，属于低轨卫星通信领域。本发明针对低轨卫星馈电切换过程中数据中断、丢失、星地存储资源大、切换时延大问题，通过卫星配置2套独立馈电链路载荷及星地协同的路由层切换的方法，解决了星地馈电链路数据可靠传输及延长有效通信时长问题。本发明可应用于各类低轨卫星及低轨卫星星座系统，可保证星地
