摘要
用矢量微分推导出光压摄动加速度对卫星位置矢量的偏导数公式，并用数值微分方法检验了公式的正确性。
After giving the solar radiation pressure model of GPS satellite,new formulas of the partial derivatives of the perturbation acceleration vector with respect to satellite position vector are led with the method of vector differential.At last the new formulas which have simpler forms and are easier for programming than that were given in[1,2]are tested nummerically.
