At 14:01 on March 5th, at the Xichang Satellite Launch Center, by the Long March 2C carrier rocket, six low-orbit broadband communication satellites successfully launch out.

The calibration methods of star trackers are mainly divided into ground calibration and on-orbit calibration.

TY-SPACE mass-produced star tracker performed well in orbit

In order to clarify the principle and method of spacecraft attitude measurement, further understand the importance of star trackers in aerospace applications and the difference from other attitude sensors, Here briefly introduces the situation of the main attitude sensors on spacecraft.

Celestial bodies maintain relative balance via gravitation and motion. Visually, all celestial bodies seem to be equidistant, and their relationship to the observer is like the relationship between a point on a sphere and the center of the sphere. This imaginary sphere with the observer as the center and an arbitrary length as the radius is called the celestial sphere.

52 TY-Space star trackers orbit successfully on June 7, 2023 to service for 26 satellites launched by the “Lijian-1 Yao-2 carrier rocket”.

Zhuque-2 successfully lifted off and became the world’s first liquid oxygen methane rocket to successfully enter orbit.

Star tracker is an device to determine the attitude by measuring the orientation of the navigation star in the spacecraft coordinate system.

Researchers have used China Sky Eye FAST to detect key evidence of the existence of nanohertz gravitational waves.

TY-SPACE provide PST3S star trackers for Gaofen 06A series satellites, the new members of the “Jilin-1” constellation.
