Different from the traditional low-orbit satellite system, the occurrence of the inter-satellite link enables the low-orbit satellites to share information and meet certain configuration requirements, so that specific tasks are cooperatively completed. For a ground measurement and control system, measurement and control requirements of an orbit configuration can be increased by supporting an inter-satellite link between low-orbit satellites, long-term management of the low-orbit satellites supporting the inter-satellite link is supported, and compared with a management task of a conventional low-orbit satellite, the remote control operation task has higher complexity and more restriction factors need to be considered when measurement and control events are arranged. The current measurement and control task planning method and the automatic process of the satellite long-term management aiming at single-satellite management design are completed by manually scheduling each functional subsystem for multi-satellite measurement and control of a satellite group supporting inter-satellite link cooperation. The problem mainly exists in a measurement and control task planning link, how to reasonably arrange measurement and control management events and schedule an event execution sequence according to long-term management requirements to improve management efficiency is a key problem to be solved by low-orbit formation satellite management.
