Abstract

The invention provides a task scheduling method and system for an imaging satellite, and relates to the field of satellite observation. The method comprises the steps of obtaining satellite resourcesand satellite tasks; acquiring satellite task observation benefits and satellite task priorities based on the satellite resources and the satellite tasks; setting a target function based on the satellite task observation benefits and the satellite task priorities, and setting constraint conditions; constructing a satellite task observation model based on the target function and the constraint conditions; acquiring a satellite task population based on the satellite task observation model; and processing the satellite task population based on a preset ant colony algorithm to obtain a satellite task observation scheme. The method is high in satellite scheduling efficiency.

Description

technical field [0001] The invention relates to the technical field of satellite observation, in particular to a task scheduling method and system for imaging satellites. Background technique [0002] With the development of science and technology, people continue to explore and develop the aerospace field. Various aircraft and satellites are manufactured and widely used in various fields, such as monitoring the ground through satellites. The user puts forward the observation task requirement to the ground station, and the ground station sends the task to the satellite, surrounds the ground, and observes the mission target, so as to obtain the information required by the user. Therefore, the use of satellites to achieve mission observation is a major research hotspot at present. [0003] With the continuous development of satellite technology, imaging satellites have come out and been widely used. Imaging satellite scheduling is mainly to plan the task set to carry out the ...
