At 15:33 (Beijing time) on August 19, 2025,China successfully launched the AIRSAT-05 satellite (HaiShao-2), theMultifunctional Test Satellite No. 2-01/02/03 (TianTuo-6), Tianyan-26(Nuowei-1), ThumbSat-1, and ThumbSat-2 — a total of seven satellites — intotheir designated orbits using the Lijian-1 Y10 launch vehicle from the JiuquanSatellite Launch Center. The launch mission was a complete success. Among them,AIRSAT-05 and Tianyan-26 are equipped with four star trackers: TYSpace’sPST4S-H1 and PST3S-H4.

AIRSAT-05

The AIRSAT-05 (HaiShao-2) satellite wasdeveloped under the leadership of the Innovation Academy for Microsatellites ofthe Chinese Academy of Sciences. Its primary payload is an X-band syntheticaperture radar (SAR), supporting wave mode, spotlight, stripmap, and scanmodes. It provides imaging with spatial resolution better than 1 meter and amaximum swath exceeding 300 km. With single, dual, and full-polarizationimaging capabilities, it also integrates a high-performance onboard intelligentprocessing module, enabling high-quality in-orbit SAR imaging and automatedextraction of ice and ocean information. The AIRSAT-05 (HaiShao-2) satellite isexpected to play a vital role in land resource surveys, disaster response,ocean environment monitoring, and global shipping security.

Tianyan-26

The Tianyan-26 (Nuowei-1) satellite is thefirst satellite of the Nuowei constellation. The satellite adopts aplatform-based integrated architecture, with modularized core components.Despite its lightweight body (about 50 kg), it carries multiple advancedpayloads, including a visible-light camera, infrared camera, and panoramiccamera. Nuowei-1 marks a new step in exploring productive forces for thedevelopment of the Nuowei Beidou system.

In line with the development trend of the"Star Era" of commercial aerospace, TYspace has taken the lead inrealizing mass production of star Trackers in China. Board-level screening,electronics testing, whole-machine thermal cycle, thermal vacuum vibration, andfield stargazing have all been completed in batches automatically. All testreports and test results are automatically output, and the remote monitoringprocess is clear and more efficient. The annual output can reach 2,000 sets,which can meet the satellite factory's mass production requirements for highperformance, high reliability, high output, and high delivery speed of star Trackerproducts. So far, TYspace star Tracker products have successfully operated morethan 600 units in orbit!
