A Method for Determining Structural Layout Parameters of Agile Satellites

Abstract

A structure layout parameter determination method of an agile satellite comprises two parts of solar panel layout parameter optimization and star sensor layout parameter optimization. An optimization goal of the solar panel layout parameter optimization is set as an energy generation value of each track of a solar panel, bounded variables of the optimization goal are track parameters, attitude parameters and solar panel effective charging conditions, and variable parameters are solar panel installation angles. Optimal values of the solar panel installation angles are determined by mathematical solution. An optimization goal of the star sensor layout parameter optimization is set as a star sensor available time period, bounded variables of the optimization goal are track parameters and attitude parameters, and variable parameters are star sensor installation angles. The star sensor installation angles are iteratively computed by mathematical solution, and an available time period optimal value of each track of a star sensor can be obtained. The structure layout parameter determination method can maximumly improve application effectiveness of the agile satellite under the premise of satisfaction of a working mode of the agile satellite and a satellite mission application mode.
