Variable-period multi-satellite emergency mission planning method and system with different scheduling mechanisms

Abstract

The present invention provides a variable-period multi-satellite emergency task planning method and system with different scheduling mechanisms, which can deal with the integration of emergency task planning by combining the planning method of fixed-period overall decision-making planning and local adjustment planning based on measurement and control opportunities The complex whole process solves the impact of the uncertain arrival of emergency missions on mission planning; considering the actual constraints that emergency missions must be noted in the command before they can be observed, and need to be downloaded from the ground station to complete, the emergency mission preprocessing plan is designed. And meet the deadline requirements of emergency tasks. At the same time, considering the characteristic that the sooner the emergency task is completed, the better, and designing the emergency task time window weighting mechanism to ensure that the emergency task is downloaded as soon as possible.

Description

technical field [0001] The invention relates to the field of satellite search, in particular to a variable-period multi-satellite emergency task planning method and system with different scheduling mechanisms. Background technique [0002] Remote sensing satellites use various remote sensors onboard to observe or search for targets on the ground or in the sea. Because remote sensing satellites have the advantages of wide coverage, long duration, and no restrictions on airspace and national boundaries, they play an important role in ocean search and military investigation. [0003] Remote sensing satellites will receive regular tasks and emergency tasks when performing observation tasks. Among them, emergency tasks need to be completed within the deadline and the earlier the completion time, the better. Different from conventional tasks, there are many emergency tasks in the existing technology. However, the prior art does not fully consider that the emergency task needs to ...
