Star sensors are an essential instrument used to determine the attitude of satellites by identifying the stars in the field of view. The high cost and large sizes of commercially available star sensors pose challenges for small satellite missions. We at the Indian Institute of Astrophysics have developed a low-cost star sensor, StarberrySense, based on the Raspberry Pi as the main controller and built from commercial off-the-shelf components. The StarberrySense was flown on the PS4 experimental orbital platform module of the Polar Satellite Launch Vehicle C-55 by the Indian Space Research Organization. This work describes the flight hardware, environmental tests in preparation for the flight, and in-orbit performance of our StarberrySense.

适用于小型卫星的低成本 Raspberry Pi 星传感器。二：StarberrySense 飞行和在轨性能

星敏感器是通过识别视场中的恒星来确定卫星姿态的重要仪器。商用星传感器的高成本和大尺寸给小型卫星任务带来了挑战。印度天体物理研究所开发了一种低成本星传感器 StarberrySense，它基于 Raspberry Pi 作为主控制器，并由商用现成组件构建。 StarberrySense 是在印度空间研究组织的极地卫星运载火箭 C-55 的 PS4 实验轨道平台模块上进行飞行的。这项工作描述了我们的 StarberrySense 的飞行硬件、飞行准备的环境测试以及在轨性能。
