本文提出了一种新的低功耗成像系统的纳卫星近距离操作。基于ARM Cortex-M3微控制器和快速静态随机存取存储器，开发了一种具有板载图像处理功能的强大独立相机模块，并根据ESTCube-1使命的要求进行了表征。该成像系统经过优化，可用于单个立方体卫星单元，利用商用现成组件和标准接口，实现具有成本效益的可重复使用设计。由此产生的43.3 mm £ 22 mm £ 44.2 mm（W£ H£ D）铝相机模块重30 g，平均功耗为118 mW，图像捕获期间的峰值为280 mW。已进行空间鉴定和压力测试。介绍了ESTCube-1 10米系绳部署监测和地球成像使命的详细案例研究。为此，使用4.4 mm远心透镜、10位640 × 480像素CMOS图像传感器、700 nm红外截止滤光片和25%中性密度滤光片。组装系统的分辨率为12.7毫米和1公里每像素的距离为10米和700公里，分别。定制的机载图像评估和高动态范围成像算法的ESTCube-1已经实施和测试。组装系统的光学校准已经进行。
This paper presents a novel low-power imaging system for nanosatellite proximity operations. A robust independent camera module with on-board image processing, based on the ARM Cortex-M3 microcontroller and fast static random access memory, has been developed and characterized for the requirements of the ESTCube-1 mission. The imaging system, optimized for use in a single unit CubeSat, utilizes commercial off-the-shelf components and standard interfaces for a cost-effective reusable design. The resulting 43.3 mm £ 22 mm £ 44.2 mm (W£ H£ D) aluminium camera module weighs 30 g and consumes on the average of 118 mW of power, with peaks of 280 mW during image capture. Space qualification and stress tests have been performed. A detailed case study for the ESTCube-1 10 m tether deployment monitoring and Earth imaging mission is presented. For this purpose a 4.4 mm telecentric lens, 10 bit 640£ 480 pixel CMOS image sensor, 700 nm infrared cut-off filter and a 25% neutral density filter are used. The resolution of the assembled system is 12.7 mm and 1 km per pixel at distances of 10 m and 700 km, respectively. Custom on-board image evaluation and high dynamic range imaging algorithms for ESTCube-1 have been implemented and tested. Optical calibration of the assembled system has been performed.
