Problems solved by technology

However, with the increasing number of satellites, the complexity of solving the model established by this traditional multi-satellite planning technology increases exponentially. Even if the intelligent optimization method is used to solve the problem, the efficiency of the solution is difficult to meet the engineering requirements under the condition of ensuring the quality of the solution. needs
In addition, the usage patterns and constraints of different observation resources are not the same, which is very complicated. Simple joint scheduling cannot achieve the desired synergistic effect

Embodiment Construction

[0077] The purpose of the present invention is to provide an imaging satellite resource calling and configuration method that can give a plan on how to schedule satellites and improve the utilization rate of satellite resources.

[0078] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. .

[0079] In one embodiment, as figure 1 As shown, the multi-satellite scheduling problem is decomposed into several single-satellite scheduling sub-problems through pre-assignment of tasks to be solved respectively. According to the task requirements, the tasks are pre-assigned, and the tasks are allocated to the appropriate satellites, and each satellite then calls a single-s...

Abstract

The invention discloses a method for calling and configuring imaging satellite resources. The method specifically includes the steps that task allocation problems are classified into one of a capacity overload problem, an energy overload problem, an energy and capacity overload problem and an energy and capacity non-overload problem according to the difference of the imaging satellite resources and extraction of features of the task allocation problems; the task allocation problems are solved by means of an algorithm engine, and the rapid selection of solving operators of the problems can be achieved according to different achievement effects of historical solution operators of the same type of problems recorded in a problem operator knowledge base in the solving process. According to the method for calling and configuring the imaging satellite resources, the scheme that how to schedule a satellite can be provided, and the utilization rate of the satellite resources can be improved.

Description

technical field [0001] The invention relates to the technical field of aerospace imaging satellite scheduling, in particular to a method for invoking and configuring imaging satellite resources. Background technique [0002] In recent years, my country's aerospace technology has developed rapidly. Aerospace technology has rapidly expanded from the field of national defense and military to the field of civilian aerospace. The number of satellites owned by my country has increased sharply, and the development and production of satellites have begun to enter the stage of mass production. The imaging satellite scheduling problem contains many resources and tasks. The traditional solution method is to adopt the idea of ​​overall optimization and apply multi-satellite joint task planning and scheduling technology to solve it. However, with the increasing number of satellites, the complexity of solving the model established by this traditional multi-satellite planning technology in...
