为了提高太阳敏感器的精度,同时实现太阳敏感器的大视场与高精度,该文提出了一种探测器复用技术,解决了精度与视场角相互制约的矛盾。该技术利用带有多组定位孔的光线引入器,将太阳敏感器的视场进行了细分,并且通过数值仿真对定位孔图案进行了优化设计。基于探测器复用技术的太阳敏感器原理样机的测试实验表明:其精度可达5″(3σ),视场角为105°×105°。该技术能够将太阳敏感器的精度提升到角秒量级,同时保持较大视场角。
In order to improve the accuracy of the solar sensor and realize the large field of view and the high precision of the solar sensor, a detector multiplexing technology is proposed to solve the contradiction between the accuracy and the viewing angle. The technology uses a light guide with a plurality of positioning holes to subdivide the field of view of the solar sensor, and the positioning hole pattern is optimized by numerical simulation. Based on the detector multiplexing technology, the principle of solar sensor prototype test results show that: the accuracy of up to 5 "(3σ), angle of view of 105 ° × 105 ° .This technology can improve the accuracy of the sun sensor to angular seconds Magnitude, while maintaining a large angle of view.
