TY-Space Technology (Beijing) Ltd.

NST20-G2 is a fully autonomous, highly reliable, high-precision, high-dynamic attitude star sensor with a dynamic performance of up to 20°/s, which can meet the high dynamic requirements of satellites. The attitude accuracy reaches 3″[3σ], which meets the requirements of satellite attitude control. The secondary sunshade ensures that the star sensor can work at a suppression angle of 25° and is not interfered by stray light outside 45°.
