With the successful orbiting of Shiyan-20 C satellite on October 29, 2022, TYSPACE added three NST20-G3 Star Trackers in orbit, providing Shiyan-20 C satellite with 1″[3σ] high-precision attitude determination services.
Developed by the Innovation Academy for Microsatellites of Chinese Academy of Science, the Shiyan-20 C satellite is mainly used for on-orbit verification tests of new technologies such as space environment monitoring.
NST20-G3 is a fully autonomous, highly reliable, high-precision, high-dynamic attitude star tracker. The attitude determination accuracy reaches 1″ [3σ], and the dynamic performance reaches 5°/s.
