Embodiment Construction
[0058] refer to figure 1 Shown flow chart, the concrete steps of the inventive method are as follows:
[0059] The first step is to obtain the input conditions. The input conditions required for the calculation mainly include: satellite configuration, geometric dimensions, and satellite surface characteristic parameters; satellite barycenter position; solar wing position, size, and surface characteristic parameters; S / L antenna position geometric dimensions and surface characteristic parameters. Prepare for pressure moment;
[0060] The second step is to calculate the radiation pressure moment of the sun on each panel of the star body according to the satellite configuration, geometric size, satellite mass center and satellite surface characteristic parameters. There is occlusion between the east panel of the star and the S / L antenna. In order to consider the influence of occlusion, the micro-element The division method is used to calculate the radiation pressure moment of t...
