Problems solved by technology

[0002] The traditional ultraviolet star-earth simulator is mainly composed of a black plate, LED lights, optical fibers, deuterium lamps, filters and modulators, etc., install LED lights in the middle of the black plate to simulate the earth, and open N light holes around the LED lights to simulate Each light-transmitting hole is equipped with an optical fiber and a deuterium lamp. The modulation disc is installed between the deuterium lamp and the entrance of the optical fiber. There are multiple sets of filters of different bands on the modulation disc. The motor drives the modulation disc to rotate to drive the filter. The rotation of the light sheet makes the optical fiber radiate ultraviolet light in different spectrum bands. This method takes up a lot of space and is complicated to operate. Since there is no optical system, it is impossible to simulate the distance between stars and the earth.

Abstract

The invention discloses an ultraviolet fixed star and earth simulator. The ultraviolet fixed star and earth simulator comprises a fixed star simulator body and an ultraviolet earth simulator body. The fixed star simulator body is used for simulating a constellation image from infinity, and the earth simulator body is used for simulating an ultraviolet earth image from infinity. The ultraviolet fixed star and earth simulator is installed on an ultraviolet navigation sensor through a vertical type adjusting mechanism, and the constellation image and the ultraviolet earth image are overlapped and recognized by the ultraviolet navigation sensor at the same time.
