Three TY-SPACE Star Trackers Support Successful In-Orbit Operation of Tianyi-49 and Kaiyun-2 Satellites

At 10:54 Beijing Time on July 22, 2026, inthe eastern sea area of Shanghai, the Gravity-1 Y4 launch vehicle, the world'slargest solid-propellant rocket, soared into the sky and successfully launchedthe Tianyi-49 satellite and Kaiyun-2 satellite. One TY-SPACE PST3S-H4 startracker and two TY-SPACE PST3S-H5 star trackers smoothly entered the designatedorbit along with the satellites, and the mission was completed successfully.

As a 50-kilogram-class space scienceexperimental satellite, the Tianyi-49 carries a small remote sensing camera andwill conduct a series of Earth observation technology verification tests afterorbit insertion.

The Kaiyun-2 University Satellite Alliancesatellite adopts an innovative dish-shaped configuration and is equipped withhigh-performance star trackers. It efficiently performs on-orbit attitudemeasurement and star map identification, ensuring stable satellite operationand platform technology verification. The space object data collected by thesatellite provides solid data support and a scientific decision-making basisfor spacecraft on-orbit safety management, space collision risk warning, andlarge-scale constellation networking planning.

The TY-SPACE PST3S-H4 and PST3S-H5 startrackers have been successfully applied in multiple satellite and satelliteconstellation projects, including the Honghu satellite, Tianyi-33 satellite,and Kaiyun-1 satellite.

TYSpace Technology (Beijing) Ltd. isprofessional focusing on advanced attitude optical sensors, especially StarTrackers for space industry. TYSpace Star Trackers successfully launched andoperating flawlessly on board of High Resolution Remote Sensing Project, LunarExploration Program and other satellites & on-orbit applications.
