Abstract :
In this article, a three-axis Ultraviolet Optical Sensor (UVOS) is designed, which can solve the problem of attitude determination for large field observation in the near-earth orbit. By applying an irregular optical system, i.e. the reflecting arrays and combined optical system, a circular large field of view is divided into 8 sub-fields. UVOS will provide the three-axis attitude information and autonomous navigation data after image overlapping and image-processing. The maximum yaw angle of the three-axis ultraviolet optical sensor is less than 0.07°, and the maximum pitch angle is less than 0.15°. The UVOS can measure 5 magnitudes. It is can be treated as an important sensor for the space vehicles of deep space exploration.
