The invention provides a dual-super satellite and a load cabin and platform cabin star sensor alignment method thereof. The method comprises the following steps: respectively reading and recording attitude quaternions, relative to an inertial system, of a satellite body coordinate system measured by a load cabin star sensor and a platform cabin star sensor; and calculating the deviation of the platform cabin star sensor relative to the load cabin star sensor, correcting the installation matrix of the platform cabin star sensor, and carrying out upper injection so as to realize alignment of the load cabin and the platform cabin star sensor. The method can meet the application requirements of the double-super satellite, provides a good technical means for high-precision observation of the double-super satellite, and has engineering application value.
本发明提供了一种双超卫星及其载荷舱和平台舱星敏感器对准方法,包括:分别读取并记录载荷舱、平台舱星敏感器测量的卫星本体坐标系相对于惯性系的姿态四元数;计算平台舱星敏感器相对于载荷舱星敏感器的偏差,修正平台舱星敏感器安装矩阵并上注,以实现载荷舱和平台舱星敏感器对准。本发明可满足双超卫星应用需求,为双超卫星高精度观测提供了良好的技术手段,具有工程应用价值。
