TapTechNews August 6th news, the first batch of组网 satellites of the Thousand Sails Constellation plan, known as the domestic Starlink, held its launch ceremony this afternoon at the Taiyuan Satellite Launch Center. This launch is about to lift off and enter orbit with the configuration of one arrow with 18 satellites. Industry experts believe that this move will become a milestone event in the history of China's low-earth orbit satellite development.

The end-user of this batch of satellites is Shanghai Yuanxin Satellite Technology Co., Ltd. It adopts the stackable flat-panel satellite platform independently developed by Shanghai GeSi Aerospace, and each satellite weighs 300 kilograms. Its G60 satellite digital factory is the first carrier of the domestic satellite Internet industrial cluster. Shanghai plans to build the first domestic satellite Internet industrial cluster integrating innovative research and development, production and manufacturing, and application landing on this basis.

According to the official plan, the Thousand Sails Constellation is expected to complete the launch of 108 satellites this year, and the first phase will launch 1296 satellites (the first stage plans to achieve regional network coverage with 648 satellites by the end of 2025, and to provide global network coverage by 2027), and in the future, it will build a networking of more than 14,000 low-earth orbit broadband multimedia satellites.

TapTechNews note: Satellites can be divided into low-earth orbit satellites (LEO), medium-earth orbit satellites (MEO), high geosynchronous orbit satellites (GEO), and high elliptical orbit satellites according to the orbital altitude. Low-earth orbit satellites operate in the orbit from 300 kilometers to 2000 kilometers above the ground and have functions such as communication, navigation, and remote sensing. Low-earth orbit satellites usually have the following multiple advantages:

Low orbit and small weight, and the satellite cost and launch cost are relatively low;

The landing signal intensity is higher, and the signal power of the satellite reaching the earth's surface will be 30 dB (that is, 1000 times) higher than that of medium-high orbit satellites, which can improve the positioning effect under the condition of occlusion and shielding, and improve availability, anti-interference and anti-spoofing capabilities;

Fast operation speed, accelerating the convergence time of high-precision positioning, and the user experience is better; it can enhance the satellite navigation signal and other advantages;

Flexible launch and rich application scenarios, etc.

At present, China has planned three ten-thousand-star constellation plans:

GW Constellation: Led by China Satellite Network Group Co., Ltd. (China Satellite Network), it plans to build a main body of the Chinese Starlink composed of 13,000 satellites.

Thousand Sails Constellation G60 Satellite Constellation plan: The satellite Internet industrial cluster is jointly built by 9 major cities in the Yangtze River Delta such as Shanghai, and it is expected to provide multi-service integrated services with 15,000 satellites by the end of 2030.

Honghu-3 (Swan Goose-3): The pre-release information (API) file submitted by Shanghai LanJian HongQing Technology Co., Ltd. to the ITU (International Telecommunication Union) shows that the Swan Goose-3 constellation plans to launch a total of 10,000 satellites in 160 orbital planes.
