针对卫星在轨太阳辐射热流计算过程中计算参数多,计算过程复杂的问题,提出了一种简化的计算方法。该方法在分析卫星、地球和太阳三者之间空间几何关系的基础上,建立了新的计算坐标系,在计算坐标系中对卫星、地球和太阳的位置进行了重新规定,并在此坐标系中推导了卫星太阳辐射热流的计算公式。运用此方法对卫星太阳辐射热流进行分析求解时,轨道参数之间的空间角度关系更为简单,仅需对7个主要参数进行计算,与传统方法相比较计算量减少了约2/3。
Aiming at the problem of calculating the parameters and the complicated calculation process of satellite solar heat flux in orbit, a simplified calculation method is proposed. Based on the analysis of the geometrical relationship among the satellite, the earth and the sun, this method establishes a new calculating coordinate system, and regulates the position of the satellite, the earth and the sun in the coordinate system. At the coordinate Department of satellite solar radiation heat flux calculation formula. When using this method to analyze and solve the heat flux of satellite solar radiation, the space angle relationship between orbit parameters is simpler. Only seven main parameters need to be calculated. Compared with the traditional method, the computational cost is reduced by about 2/3.
