现代科学空间任务对卫星运动预测和分析的准确性提出了很高的要求。一方面，使命的设计和准备需要精确的轨道传播模型。另一方面，使命数据分析本身也需要这些模型，从而能够识别可能影响科学信号的意外干扰、耦合和噪声。太阳辐射压是地球轨道卫星非引力扰动的主要贡献者之一，我们提出了一种数值模拟方法。这里介绍的建模方法允许列入详细的航天器几何形状，光学表面特性，这些光学表面特性（材料退化）的变化在使命寿命。通过使用的几何定义，表面属性定义，和使命定义的法国显微镜使命，我们突出了一个准确的太阳辐射压力建模与传统的方法，如炮弹模型或翼盒的方法的好处。我们的分析表明，实施一个详细的卫星几何形状和考虑不断变化的表面特性允许检测的系统，这是无法检测到的传统模式。
Modern scientific space missions pose high requirements on the accuracy of the prediction and the analysis of satellite motion. On the one hand, accurate orbit propagation models are needed for the design and the preparation of a mission. On the other hand, these models are needed for the mission data analysis itself, thus allowing for the identification of unexpected disturbances, couplings, and noises which may affect the scientific signals. We present a numerical approach for Solar Radiation Pressure modelling, which is one of the main contributors for nongravitational disturbances for Earth orbiting satellites. The here introduced modelling approach allows for the inclusion of detailed spacecraft geometries, optical surface properties, and the variation of these optical surface properties (material degradation) during the mission lifetime. By using the geometry definition, surface property definitions, and mission definition of the French MICROSCOPE mission we highlight the benefit of an accurate Solar Radiation Pressure modelling versus conventional methods such as the Cannonball model or a Wing-Box approach. Our analysis shows that the implementation of a detailed satellite geometry and the consideration of changing surface properties allow for the detection of systematics which are not detectable by conventional models.
