Problems solved by technology

Due to the long load shade, and in order to meet the carrying envelope, the length of the support frame of the north and south solar cell arrays is limited, which will cause the solar cell arrays to be blocked by the stars when the satellite is in orbit, resulting in a decrease in the overall star power of the satellite. , in order to reduce the impact of star occlusion on the entire star, it is necessary to analyze the occlusion situation to provide a basis for the entire star design

Abstract

The invention discloses an analysis and calculation method for orbital shading of a geostationary orbit satellite solar cell array and relates to the field of the space technology. The method includes the steps of 1, analyzing annual average change rules of solar illumination angle of a geostationary orbit satellite; 2, analyzing change rules of orbital shading of the satellite solar cell array by stars; 3, calculating and simulating orbital shade area of the cell array according to the analysis results. The analysis and calculation method has the advantage that the basis for the design of solar cell array substrate configuration is provided.

Description

Technical field [0001] The invention relates to a geostationary orbit remote sensing satellite, and more specifically, to an analysis and calculation method for the solar cell array being blocked by a star when the geostationary orbit satellite is in orbit. Background technique [0002] A large-scale geostationary orbit remote sensing satellite platform generally consists of a service cabin and a propulsion cabin, and the payload is generally a large-size camera installed on the platform to the ground. Due to the long load hood, the length of the support frame of the north and south solar arrays is limited to meet the carrying envelope. This will cause the solar arrays to be blocked by the stars when the satellite is flying in orbit, resulting in a decrease in the power of the satellite. In order to reduce the impact of the occlusion of the star on the entire star, it is necessary to analyze the occlusion situation to provide a basis for the entire star design. Summary of the in...
