FIELD: physics.
SUBSTANCE: active ultraviolet solar sensor for orientation systems of small-size spacecraft includes a natural diamond-based photodetector at the entrance window of which solar energy falls and a low-noise preamplifier. The natural diamond-based photodetector functionally combines both an ultraviolet optical filter and an ultraviolet photodetector. Selective separation of the ultraviolet region from the solar spectrum and conversion thereof to an electrical signal is carried out in the natural diamond-based photodetector and signal amplification is carried out in the low-noise preamplifier.
EFFECT: high reliability of the sensor and accurate determination of the direction of the Sun.
