TY-Space NST4S-A2 Nano Star TrackersSupport Successful On-Orbit Operations of Four SAR Satellites

At 18:50 Beijing Time on September 19, 2026,a Long March 2D launch vehicle lifted off from the Taiyuan Satellite LaunchCenter, successfully sending four Synthetic Aperture Radar (SAR) satellitesinto their designated orbits. Eight TY-SPACE NST4S-A2 nano star trackersonboard the satellites entered orbit smoothly.

The four SAR satellites were independentlydeveloped by GalaxySpace (Beijing) Technology Group Co., Ltd. They carryhigh-resolution SAR payloads as well as onboard intelligent processing andmission-planning payloads.

The TY-SPACE NST4S-A2 nano star trackersused in this mission have been successfully applied to multiple satellites andconstellation projects, including Shijian-29 A and B, Qilu-3, SATech-01, andTaijing-4 01.
