Problems solved by technology

[0005] Through the review of the existing technology, we can see that most of the previous studies on the task scheduling problem of agile imaging satellites only started from the method, and oversimplified the research object, such as ignoring multiple nearby observation tasks with overlapping time windows The mutual influence between them does not consider the constraints of observation swing angle, attitude adjustment time, longest continuous working time, etc.
Therefore, the mission planning results obtained by using existing technologies are often conservative, and cannot give full play to the earth observation capabilities of agile satellites, resulting in a waste of satellite resources in orbit

Abstract

The invention provides a video satellite ground gaze task planning method based on ant colony algorithm with tabu list. This method takes into account the observation time window. An improved ant colony algorithm with tabu list is proposed for mission planning computation, which can make the video satellite select and arrange the targets in the designated area under the condition that the time, space and energy resources are limited, and ultimately maximize the benefit of the observation mission. The invention has the advantages of strong engineering applicability, flexible configuration and fast planning calculation, can further excavate the earth observation capability of the video satellite and improve the utilization rate of the on-orbit satellite resources.

Description

technical field [0001] The invention relates to the technical field of aerospace mission planning, in particular to a method for planning a mission of staring at the ground of a video satellite based on an ant colony algorithm with a taboo list. Background technique [0002] Video satellite is a new type of earth observation satellite. Compared with traditional earth observation satellites, it can stare and image a certain target area and realize continuous observation of the target area for a period of time. It has important military and civilian applications. value. Ground staring imaging is the main working mode of video satellites. The satellite adjusts the attitude of the star according to the needs through the attitude control system, so that the optical axis of the on-board optical sensor is always aligned with the ground target, so as to realize uninterrupted imaging and obtain the dynamic information of the target. In particular, in emergency operations such as reg...
