We propose to explore the processing and design challenges facing next-generation star trackers. These spacecraft sensors take pictures of the sky, compare them to a star map, and use this information to determine the satellites' orientation to a very high degree of accuracy. Star tracking is the only attitude sensing technology that permits high resolution attitude measurement, and complete (i.e three-axis) orientation measurement from a single device. These sensors have been used for decades, but there is increasing interest in enhancing their operational capabilities and affordability.

我们建议探索下一代星形追踪器面临的处理和设计挑战。这些航天器传感器为天空拍照，将它们与星图进行比较，然后使用此信息来确定卫星的方向至少准确。星形跟踪是唯一允许从单个设备完成高分辨率态度测量并完成（即三轴）方向测量的态度传感技术。这些传感器已经使用了数十年，但是对增强其运营能力和负担能力的兴趣越来越高。
