At 11:00 am on January 13, 2025 Beijing time, China's Taiyuan Satellite Launch Center successfully launched the Micro Li Space 01 group of satellites into the sea near Haiyang, Shandong using the Jielong III carrier rocket in a "one rocket, ten satellites" manner. The satellites entered the predetermined orbit smoothly and the launch mission was a complete success.

After the successful launch of the S2 star of the Micro Space One system by Tianyin Interstellar on July 1, 2020, the S3 and S4 stars of the Micro Space One system on September 6, 2022, and the S5 and S6 stars on October 7, 2022, Tianyin Interstellar will once again escort the low orbit constellation system of Micro Space at the beginning of 2025, winning a good start!

The 10 satellites successfully in orbit this time were equipped with 12 Tianyin Interstellar PST3S-H5 star sensors.

The Tianyin Interstellar PST3S-H5 star sensor applied on the Micro Li Space 01 satellite is a new product of the PST3 series, equipped with a secondary shading cover. It is not only small in size, light in weight, and low in energy consumption, but also has a total body weight of 130g (including the cover), a positioning accuracy of better than 3 '' [3 σ], a dynamic performance of 3 °/s, and a 35 ° solar suppression angle. It has excellent comprehensive performance and is suitable for various satellites. It can also be customized according to user needs.

Micro space low orbit constellation system

The Micro Space 01 group of satellites is the first batch of networked satellites in the "Micro Space Low Earth Orbit Constellation System". This system is an integrated constellation system consisting of hundreds of low Earth orbit satellites and ground systems, which can provide real-time low-cost, highly reliable centimeter level high-precision positioning commercial services for global users.

Following the development trend of the "star era" in commercial aerospace, Tianyin Interstellar has taken the lead in achieving mass production of star sensors in China. Automated batch production has been achieved for board level screening, electronic testing, whole machine thermal cycling, thermal vacuum vibration, and field observation of stars. All test reports and results are automatically output, and the remote monitoring process is clear and more efficient. The annual output can reach 2000 sets, which can meet the batch requirements of satellite factories for high-performance, high reliability, high output, and high delivery speed of star sensor products.

As of now, over 550 units of Tianyin's interstellar star sensor products have been successfully operated in orbit! In 2025, Tianyin Interstellar warmly looks forward to working together with global commercial aerospace clients to seize the opportunities of the booming development of commercial aerospace and create a new chapter and a better future!
