A novel design of digital sun sensor with the real panoramic view field is proposed. The optical system is composed of a filter and fisheye lens. The sun sensor has features like low power consumption,large field,and high precision which can meet the requirement of micro-satellites. According to the mechanism of the sun sensor,both the model and the entity of the sun sensor are made. After testing on the experiment platform,the results indicate that the sun sensor has a large field of 180°×360°,and in the field of 160°×360°,the precision is less than 0.18°in 3δ. The power consumption of the sensor is 150 mW. The results can meet the requirement of attitude determination system on the sun sensor.%本文提出一种新型的全视场数字太阳敏感器设计方法，其光学系统由全景鱼眼镜头和滤光膜组成。采用低功耗设计，在满足精度的要求下，使其能够适应微小卫星对于数字太阳敏感器功耗的限制。从工作原理出发，建立起该敏感器模型并通过软硬件实现，利用太阳模拟器对数字太阳敏感器进行标定及误差分析。实验表明，基于全景鱼眼镜头的数字太阳敏感器的视场为180°×360°，在160°×360°视场的测量3δ精度优于0.18°，整机功耗150 mW，能够满足微小卫星姿态确定系统对于数字太阳敏感器的需求。
