The invention relates to the technical field of satellite communication, and provides a satellite load pointing calculation method, device and equipment and a storage medium, and the method comprises the following steps: obtaining conversion information between an inertial system and a star sensor measurement coordinate system according to the inertial system and rotation information between the inertial system and the star sensor measurement coordinate system; the star sensor is mounted on a satellite load of a local-end satellite; and then, according to the conversion information, the corresponding installation information of the star sensor on the satellite load, and a first pointing vector of the satellite load of the local-end satellite pointing to the target-end satellite under the inertial system, obtaining a target pointing vector of the satellite load pointing to the target-end satellite under the load coordinate system. According to the invention, the calculation time of satellite load pointing is shortened.

    本发明涉及卫星通信技术领域,提供一种卫星载荷指向的计算方法、装置、设备和存储介质,该方法包括:根据惯性系、惯性系与星敏感器测量坐标系之间的旋转信息,得到惯性系与星敏感器测量坐标系之间的转换信息;星敏感器安装在本端卫星的卫星载荷上;然后,根据转换信息、星敏感器在卫星载荷上对应的安装信息,以及惯性系下本端卫星的卫星载荷指向目标端卫星的第一指向矢量,得到载荷坐标系下卫星载荷指向目标端卫星的目标指向矢量。本发明缩短了卫星载荷指向的计算时间。
