引言粗太阳敏感器通常用在卫星上作为姿态确定系统的一部分。它的功能基本上是作为“方向余弦”敏感器,其输出近似正比于敏感器瞄准线与卫星至太阳矢量之间夹角的余弦,视场近似于半球。典型的敏感单元是硅太阳电池,它所产生的电流大小与入射其表面的能通量成正 Introduction Coarse sun sensors are commonly used on satellites as part of attitude determination systems. Its function is basically as a “cosine” direction sensor whose output is approximately proportional to the cosine of the angle between the line of sight of the sensor and the satellite-to-sun vector, and the field of view approximates the hemisphere. A typical sensitive cell is a silicon solar cell, which generates a current that is positive in the amount of energy it impinges on its surface
