高保真度轨道传播要求详细了解空间物体上的太阳辐射压力。太阳辐射压力不仅取决于空间物体的形状和姿态，而且还取决于物体每个表面的吸收和反射特性。这些属性通常以简单的方式建模，但在这里由表面双向反射分布函数描述。存在几种解析双向反射分布函数模型，并且通常是由模型内的参数表示的照明角度和材料特性的复杂函数。一般来说，太阳辐射压力的计算结果将需要一个耗时的数值积分。如果需要在真实的时间内对各种材料特性进行多个太阳辐射压力计算，则这可能是不切实际的;例如，在估计特定表面参数的过滤器中。本文提出了一种方法…
High-fidelity orbit propagation requires detailed knowledge of the solar radiation pressure on a space object. The solar radiation pressure depends not only on the space object’s shape and attitude, but also on the absorption and reflectance properties of each surface on the object. These properties are typically modeled in a simplistic fashion, but are here described by a surface bidirectional reflectance distribution function. Several analytic bidirectional reflectance distribution function models exist, and are typically complicated functions of illumination angle and material properties represented by parameters within the model. In general, the resulting calculation of the solar radiation pressure would require a time-consuming numerical integration. This might be impractical if multiple solar radiation pressure calculations are required for a variety of material properties in real time; for example, in a filter where the particular surface parameters are being estimated. This paper develops a method...
