Zhixing 3A satellite successfully put into orbit on November 14, and TY-SPACE PST3S-H4 star tracker successfully service for it, and the performance of PST3S-H4 work well and stable in orbit.

On January 17, 2022, “Shiyan 13 experimental satellite” was successfully launched from the Taiyuan Satellite Launch Center and entered the predetermined 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.

Beijing Time AM10:45 23rd JULY, the Long March-2D rocket successfully launched out from the Taiyuan Satellite Launch Center. Four satellites, including GalaxySpace Lingzhi 02-03 and GalaxySpace Lingxi-03, had launched into LEO.

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”.
