在卫星动力学定轨中,太阳辐射压是一个重要的摄动因素,特别是对中高轨卫星的轨道。为了消弱太阳辐射压的影响,已经建立有诸多太阳辐射压模型,对应方法主要包括解析和经验两类,但各有优缺点和适用范围。基于现有方法的优点和卫星实际运行环境,对复杂结构卫星建立了一种结合预先解析法采样和运行后自适应改正的联合方法以趋近卫星真实辐射压环境的太阳辐射压模型;并对该模型进行了模拟计算。结果表明,该模型在轨道计算和自校正过程均取得了良好的效果。
Solar Radiation pressure is one of significant perturbation factors in the calculation of dynamic satellites orbits, especially for the mid-high orbit satellites. In order to remove the effects of radiation pressure on mid-high orbit satellites, researchers have developed various radiation pressure models, including empirical and analytical models. According to their advantages or disadvantages and the real satellite space environment, this paper establishes a model for complex structure satellites combining prior sampling satellites in an analytical model with self-correcting method in operation, which approximates the real radiation pressure circumstances. The simulation tests and analysis show good results in both orbit determination and self-correction.
