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恒星跟踪器面临的处理和设计挑战。这些航天器传感器拍摄天空的照片，将它们与星图进行比较，并使用这些信息以非常高的精度确定卫星的方向。星跟踪是目前唯一一种能够实现高分辨率姿态测量，并能在单个设备上完成(即三轴)方位测量的姿态传感技术。这些传感器已经使用了几十年，但人们对增强它们的操作能力和负担能力越来越感兴趣。
