Abstract

The embodiment of the invention discloses a four-quadrant gallium arsenide solar sensor assembly and a preparation method thereof. A four-quadrant single-junction gallium arsenide photocell is prepared by using a corrosion isolation method, so that the solar sensor has the wide operating temperature range and the excellent space-resistant irradiance performance. The four-quadrant gallium arsenidesolar sensor assembly having advantages of small size, light weight, high precision, and the like can be applied to the micro-nano satellite attitude control system. In addition, on the basis of fixedconnection between a base and a printed circuit board, the overall packaging of the photocell is realized; and no additional packaging structure is needed, so that the structure of the solar sensor is simplified.

Description

technical field [0001] The embodiments of the present invention relate to the field of aerospace technology, and in particular to a four-quadrant gallium arsenide solar sensor assembly for a micro-nano satellite attitude control system and a preparation method thereof. Background technique [0002] Micro-nano satellites have become the most popular research direction in the field of commercial aerospace. Micro-nano satellites have the characteristics of light weight, small size, and short development cycle. The attitude control system is a very important subsystem of the satellite, and the sun sensor and star sensor are the most commonly used attitude control positioning methods. However, the cost of star sensors is high, the quality and volume are relatively large, and the power consumption is also higher. The sun sensor is a commonly used photoelectric attitude control sensor. It can determine the orientation of the sun vector in the star coordinates by sensitive to the o...
