Star sensor (SS) is one of the most critical instrument on-board a spacecraft when it comes to attitude determination and control. Capability of providing precise attitude information makes it even more important for high resolution imaging satellite with stringent pointing requirements. At the same time, these instruments are highly sensitive to bright objects like Sun and Earth Albedo. In this paper, selection of star sensor mounting has been elaborately studied and presented for missions primarily performing highly agile Earth imaging. This paper addresses selection factors like Sun and Earth avoidance from bore-sight axis, orbit altitude and local time, angular separation between SS, sensitivity of SS on body axis and functional availability during imaging. Results are presented in the form of available mounting options and the way they satisfy geometrical constraints over a year.

用于高度灵活的地球成像卫星的星传感器安装

就姿态确定和控制而言，星传感器 (SS) 是航天器上最关键的仪器之一。提供精确姿态信息的能力使得它对于具有严格指向要求的高分辨率成像卫星更加重要。同时，这些仪器对太阳和地球反照率等明亮物体高度敏感。在本文中，针对主要执行高度敏捷地球成像的任务，对星传感器安装的选择进行了详细研究和介绍。本文讨论了诸如太阳和地球避开视轴、轨道高度和当地时间、SS 之间的角间距、SS 对体轴的灵敏度以及成像过程中的功能可用性等选择因素。
