On Chip Digital Sun Sensor Based on SiP Technology
-
摘要:
设计了一种新型的数字式太阳敏感器。采用SiP(Stystem in Package)设计,将滤光片直接安装于探测器上。此设计减小了数字式太阳敏感器的体积与质量,可提高其可靠性。所设计的数字式太阳敏感器可用于深空探测卫星系统的太阳捕获和太阳定向,同时,也可作为星上其他光电敏感器的监护仪器,防止其他光学敏感器被强光损坏。最后,完成了原理样机的研制与标定,并在外场进行了太阳光斑的拍图测试。实验表明所提出方法可行,可满足火星探测、深空探测的使用需求。
Abstract:A new type of digital sun sensor is introduced which is designed by SiP technology. Filters are installed on the image sensors. By using the proposed design, the mass and volume of the sun sensors, are decreased, while the reliability is increased. In deep space, the digital sun sensor captures solar position and protects the other optics sensor from sunshine. Calibration has been done and sun spot is captured by the experimental prototype.
