Virtual constellation-based resource alliance construction method for a cooperative tas

Abstract

The invention provides a virtual constellation-based resource alliance construction method for a cooperative task, and relates to the field of satellite resource organization. The method comprises thesteps that when a virtual constellation management and control system receives a to-be-processed task, a plurality of satellites are selected according to demand information of the to-be-processed task to form a candidate satellite set, one satellite is randomly selected from the candidate satellite set to serve as a satellite leader, and the to-be-processed task is sent to the satellite leader;When the satellite leader receives the to-be-processed task, the pursuit interest degree, reliability, timeliness and income value of each satellite in the candidate satellite set are calculated for the to-be-processed task; an objective function is determined; And a satellite alliance corresponding to the to-be-processed task is determined according to the objective function, and executing the to-be-processed task by utilizing the satellite alliance. According to the invention, satellite resources can be effectively organized and optimized.

Description

technical field [0001] The invention relates to the technical field of satellite scheduling, in particular to a method for constructing a resource alliance based on a virtual constellation-based collaborative task. Background technique [0002] Satellites have a wide range of application and use value in many fields, but because the functions and capabilities of satellites are limited by themselves, that is, the orbit of satellites is constant and fixed, it is impossible to monitor a single target in real time and uninterruptedly. Periodic imaging of the target, so it is not possible to conduct effective reconnaissance and coverage of the target in the target area in a timely and effective manner, and cannot meet the satisfactory needs of users. Therefore, in the actual satellite observation, there is a trend of multi-satellite joint earth observation , the concepts of centralized satellite formation and satellite constellation also emerged. Although the imaging coverage of ...

[0002] Satellites have a wide range of application and use value in many fields, but because the functions and capabilities of satellites are limited by themselves, that is, the orbit of satellites is constant and fixed, it is impossible to monitor a single target in real time and uninterruptedly. Periodic imaging of the target, so it is not possible to conduct effective reconnaissance and coverage of the target in the target area in a timely and effective manner, and cannot meet the satisfactory needs of users. Therefore, in the actual satellite observation, there is a trend of multi-satellite joint earth observation , the concepts of centralized satellite formation and satellite constellation also emerged. Although the imaging coverage of these satellite combinations is relatively large and the revisit period is short, compared with the development speed of the current mission requirements, it has been unable to efficiently meet tasks, and because these satellite combinations must develop, launch, manage and maintain satellites, the cost of their construction is high
