【摘要】：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。
[Abstract]:The solar radiation pressure is an important perturbation factor in satellite dynamic orbit determination, especially for the orbit of a satellite in the medium and high orbit. In order to reduce the influence of solar radiation pressure, many solar radiation pressure models have been established. The corresponding methods mainly consist of analytical and empirical methods, but each has its own advantages and disadvantages and its scope of application. Based on the advantages of the existing methods and the actual operating environment of the satellite, In this paper, a combined method of pre-analytical sampling and post-operational adaptive correction is proposed for the complex structure satellite to approach the satellite's real radiation pressure environment, and the model is simulated and calculated. The model has achieved good results in orbit calculation and self-tuning process.
