设计了一种三轴紫外敏感器,解决了近地轨道大视场观测问题。通过非常规光学系统,即反射阵列组合式光学系统,将一圆型大视场分成八个子视场成像、叠加后经图像处理,为卫星提供三轴姿态信息和自主导航数据。三轴紫外敏感器标定精度为偏航小于0.05°,俯仰小于0.05°,滚动小于0.05°。研制成的工程样机,通过观星试验和利用星模拟器测试,三轴紫外敏感器可以观测到5等星;紫外波段敏感器可以作为是深空探测航天器重要敏感器之一。

Three-axis Ultraviolet Optical Sensor (UVOS) is designed. The observation problem for a very wide field of view is solved in the orbit for near earth. By the irregular optical system that is reflecting arrays and combined optical system,the circular wide field of view is divided into 8 sub-fields. UVOS provides both three-axis attitude and autonomous navigation data by utilizing image-overlap and image-processing. Calibration precision for UVOS is under yaw angle 0.05°,pitch angle 0.05°and roll angle 0.05°. Engineering Model is finished. By means of observing star experiment and star simulator experiment,UVOS can measure 5 magnitudes. UVOS is one of the important sensors for space vehicles of deep space exploration
