Abstract

The invention provides a satellite task scheduling method and system based on time window segmentation, and relates to the field of satellite scheduling. The method comprises the following steps: obtaining a visible time window of a satellite task; discretizing the visible time window to obtain an observation time window; performing real number encoding on the satellite task based on the observation time window to obtain a satellite task sequence; acquiring a satellite task population based on the satellite task sequence; performing crossover operation on the satellite task population based ona preset two-generation competitive optimization algorithm; and performing mutation operation on the satellite task population after the crossover operation based on a double-gene mutation method toobtain a satellite task scheduling scheme. According to the invention, the efficiency of satellite observation tasks is improved.

Description

technical field [0001] The invention relates to the technical field of satellite scheduling, in particular to a satellite task scheduling method and system based on time window division. 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 and the ground station explain the mission requirements, and the ground station notifies the mission to the satellite, and 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, the agile earth observation satellite comes out. It can rotate in the three dimensions of pitch, yaw and ...
