Multi-satellite cooperative task planning method and system based on handover probability

The invention provides a multi-satellite cooperative task planning method based on handover probability. The method comprises the following steps: step 1, a task transfer satellite acquires state information and an error model of a to-be-observed target; 2, the task planning satellite maintains state information of all satellites in a constellation, and obtains to-be-observed target information and an error model sent by the task transmission satellite at the same time; step 3, the task planning satellite selects a task receiving satellite according to the state information of each satellite and the target to be observed in the constellation, and sends a task execution command to the task receiving satellite; and 4, the task receiving satellite detects the target to be observed according to a command, completes a target receiving task and feeds back the target receiving task to the task planning satellite. 本发明提出一种基于交接概率的多星协同任务规划方法，包括：步骤1，任务传递星获取待观测的目标的状态信息和误差模型；步骤2，任务规划星维护星座内所有卫星的状态信息，同时获取所述任务传递星发送的待观测的目标信息和误
