A tracking and detailed reconnaissance system is designed for space-based ultraviolet (UV) tracking requirement. The system consists of two parts, tracking camera and detailed reconnaissance camera. Dual field of view and dual angular resolution are achieved by combining telescope system and relay lens. The telescope system is Mangin-Cassegrain structure, with diameter of 100 mm, focal length of 605 mm. For the tracking camera, the wavelength range is 250~400 nm, the field of view is 2.5°×1.9°, and the angular resolution is better than 180 μrad. For the detailed reconnaissance camera, the wavelength range is 200~360 nm, the field of view is 0.15°×0.11°, and the angular resolution is better than 13 μrad. The modulation transfer function (MTF) of tracking camera is better than 0.9, and the MTF of detailed reconnaissance camera is better than 0.8. The results meet the requirements of specifications through the design and optical software analysis.
