At 19:01 on August 4, 2021, the LongMarch-6 carrier rocket successfully put the two β satellites into orbit from the Taiyuan Satellite Launch Center, marking a complete success of the launch mission, that 2 more TY-SPACE NST4S-A2 star trackers orbit service well. Then we have 154 sets of products in total out there in space.

This two Beta satellites were developed by Shanghai Microsatellite Engineering Center, which developed the 2 α satellites with 4 TY-SPACE NST4S-A2 star trackers had been orbital about 2years, and worked on a new launch mission of γ satellites.

TY-SPACE’s NST4S-A2 star tracker is a fully autonomous, ultra small, and high precision attitude sensor. Its 25° sun exclusion angle by the secondary baffle guarantees that the star tracker will work well without disturbed by stray light at 25° sun exclusion angle .
