Multi-satellite emergency task planning method and device considering instruction injection

Abstract

The invention provides a multi-satellite emergency task planning method and device considering instruction injection. According to the method, a plurality of scheduling decision moments are determinedaccording to an observation and control station and a visible time window of each satellite, whether an emergency task is added is judged at each scheduling decision moment, therefore, the added emergency tasks can be timely discovered, and the processing efficiency of the emergency tasks is improved. Available visible time windows of the tasks are screened by use of injection completion time, and therefore it is guaranteed that observation of the relevant tasks is not performed unless injection is completed. When the available visible time windows are selected for the emergency tasks, a completion deadline of the emergency tasks is considered, and therefore it is ensured that the emergency tasks are completed before the predetermined completion deadline. A precise algorithm is utilized to perform task planning on a weighted sum of the emergency tasks and conventional tasks, therefore, a target available time window can be quickly arranged for each emergency task, planning efficiencyand benefit of the emergency tasks can be improved, and the overall task completion rate can be guaranteed.

Description

technical field [0001] The invention relates to the field of satellite mission planning, in particular to a method and device for multi-satellite emergency mission planning considering command upvoting. Background technique [0002] With the continuous development of satellite technology and the continuous improvement of users' demand for remote sensing data, earth observation satellites have begun to play an increasingly important role in emergency tasks such as major natural disasters and emergencies, and have become an important means of obtaining information. In the application process, the satellite images a specific area of ​​the surface according to the relevant requirements, and sends the formed image to the receiving station on the ground. [0003] At present, satellite mission planning is mainly oriented to fixed-period static mission planning. The mission planning method generally adopts constrained optimization modeling, comprehensively considers the constraints ...
