Multi-satellite online collaborative scheduling method

The invention discloses a multi-satellite online collaborative scheduling method. The method comprises the following steps: Step 1: each satellite generates a pre-planned observation plan for a conventional target and executes the current observation plan; Step 2: when a new emergency target arrives, the main satellite screens load information capable of executing the task and sends the same to anexecution satellite; Step 3, the satellites locally calculate the visibility relationship with the target after receiving the information, generate and send observation report to the main satellite;Step 4, the main satellite determines the satellites that is about to execute the observation task according to the observation reports, and allocates the task to the satellites that is about to execute the new emergency target; and Step 5, the observation task execution satellites add the new coordinated task to the future planned task and update own observation schemes and execute the new observation planning schemes.
