In the cold crystal winter night sky, in the sparkling various stars, Orion’s 7stars are shining bright and clear.

Developed by Chang Guang Satellite Technology Co., Ltd., the “Xiamen Tianwei Science and Technology No. 1 pilot satellite” (“Jilin No. 1” MF02A01 satellite) successfully in orbit on February 27, 2022.

The star tracker is a high-precision space attitude measurement device with the stars as the reference system and the starry sky as the working object.

On January 17, 2022, the test satellite 13 was successfully launched and entered the predetermined orbit from the Taiyuan Satellite Launch Center. TY-SPACE N4G star trackers  provide the astronomical attitude positioning services.

As early as the year 36 AD, Chinese historical records documented the appearance of over 100 meteors of the Perseid meteor shower.

The highest detection accuracy of the earth’s magnetic field satellite in China – “Macau Science-1” , entered the predetermined orbit on May 21. TY-Space PST3S-H5 star tracker provides attitude determination service for it.

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.
