Simulation of Influential Factors on Spacecraft’s Solar Pressure Area

Abstract

Solar radiation pressure（SRP）area is one of the key parameters of orbit determination and prediction in deep space detection，and directly affecting the prediction precision. The calculating method of SRP area based on target characteristics is used，and the sphere，cube，cylinder and cone are chosen to be analytical targets，assuming the materials are purely diffuse，purely specular and mixed surface separately. While the attitude angle changing from 0° to 360°，the influences of the surface materials，size and the shape of the target on the total SRP area of the target are analyzed，the general laws governing influential factors are described by comparing simulated results. These conclusions can provide reference for further research on SRP modeling solution and spacecraft design.
