An Analysis Method for Multi-satellite-to-Multiple Demand Planning Imaging

Abstract

The invention relates to an analysis method for multi-satellite-to-multiple-demand planning imaging, which belongs to the field of aerospace remote sensing technology. The method determines a set of orbital periods by confirming a set of needs, a set of satellites performing tasks, and a task time interval, and creates a copy of the set of needs , cyclically calculate the local maximum benefit planning selection for each orbit period, and realize a planning imaging analysis that can quickly obtain the multi-satellite-to-many demand with a large profit value. This analysis method is different from the exhaustive method. The present invention uses heuristic The local optimal algorithm of the formula greatly saves the amount of calculation, and can obtain relatively better results within an ideal time. At the same time, compared with manual processing, the present invention can be executed automatically and quickly, and the analysis results can be used for satellite planners and satellite planners alike. Business personnel are required to provide decision-making basis for mission planning, which reduces the manpower consumption of satellite control work, saves time and improves efficiency.

Description

technical field [0001] The invention relates to the technical field of aerospace remote sensing, in particular to an analysis method for multi-satellite to multi-demand planning imaging. Background technique [0002] At present, when planning multiple remote sensing satellites to image multiple requirements, manual selection of requirements and resolution of conflicts are often performed manually. When there are a large number of requirements that need to be photographed, demand selection and conflict resolution often take up a large part in the satellite management and control work. The proportion is too large, time-consuming, inefficient, and consumes a lot of human resources; at the same time, the judgment of the impact of demand selection on the income value can only be limited to conflicting demands, and there is no way to observe changes due to local demand selection , the resulting method for the effect on overall returns. [0003] [1] When multiple satellites image ...

Problems solved by technology

[0008] Based on this, it is necessary to provide an analysis method for multi-satellite-to-multiple-demand planning and imaging in view of the problems existing in the existing imaging methods for planning multiple remote sensing satellites to multiple requirements. Set their respective "local maximum income" planning options and their income values, which is convenient for business personnel to make decisions between these different demand sets and their planning options. At the same time, the present invention can improve the use efficiency of satellites and better exert the maneuverability of satellites
