Embodiment Construction

[0018] The drawings constituting a part of the present invention are used to provide a further understanding of the present invention, and the schematic embodiments and descriptions of the present invention are used to explain the present invention, and do not constitute an improper limitation of the present invention.

[0019] like figure 1 As shown, the present embodiment provides a method for dynamic allocation of remote sensing satellite mission planning energy, the method is specifically:

[0020] Step 1. According to the average imaging start-up time (average start-up time) of each orbit of satellite N orbits (average start-up time), it is judged whether the start-up time of satellite pre-planned N orbital imaging (the start-up time of pre-planned remote sensing satellites on each track of N orbits) needs to be carried out. Dynamic allocation of energy. If yes, perform dynamic energy allocation and go to step 2; if not, do not need to perform dynamic energy allocation. ...

Abstract

The invention provides a dynamic distribution method of remote sensing satellite mission planning energy. The method specifically comprises the following steps: 1, ; according to the average startup time of each orbit of the satellite N orbit and the pre-planned startup time of the satellite on each orbit, judging whether dynamic energy distribution needs to be carried out or not, If so, selectingthe orbit OrbTmax with the maximum residual redundant energy and the minimum circle number and the orbit OrbNmax with the maximum number of targets to be surveyed and mapped and the maximum circle number; calculating the amount of the residual redundant energy in the OrbTmax orbit needing to be allocated to OrbNmax, and allocating the amount according to the amount; when the residual redundant energy in the track with the residual redundant energy is 0 or the target number to be surveyed and mapped of the track with the target number to be surveyed and mapped is 0, stopping energy distribution, and otherwise, entering a new round of energy distribution; and replanning the start-up time of each orbit of the satellite. Satellite energy is fully and efficiently utilized, and the satellite imaging surveying and mapping efficiency is improved.

Description

technical field [0001] The invention belongs to the field of remote sensing satellite task planning, and in particular relates to a dynamic allocation method of remote sensing satellite task planning energy. Background technique [0002] Earth observation remote sensing satellites are artificial earth observation satellites used as aerospace space remote sensing platforms, which account for a large proportion of various satellites. Earth observation remote sensing satellites use spaceborne remote sensing loads to obtain information such as images and signals of ground targets, and transmit the obtained information back to satellite ground stations or relay satellites through radio waves, and obtain detailed data or information about the earth after analysis and processing . Earth observation remote sensing satellites are not only applied to environmental monitoring, weather forecast, national land census, etc., but also to national defense and military fields, such as milit...
