Recently, my country launched a new satellite at the Taiyuan Satellite Launch Center.

Use Long March 6A carrier rocket

Successfully launched the Qianfan Polar Orbit 01 satellite group (also known as the G60 constellation)

The first batch of 18 satellites were sent into the planned orbit

The Qianfan Polar Orbit 01 satellite group was successfully launched this time

It is known as the domestic "Starlink"

The first batch of satellites for the "Thousand Sails Constellation" project

The launch mission was a complete success

Not only China's satellite internet

Milestones in the history of development

‌It is also regarded as the first batch launch of the Chinese version of "Starlink"

It marks China's global satellite

An important step forward in the Internet

As soon as the news came out, netizens were very excited

Pay tribute to science and technology workers

What about this Chinese version of Starlink?

What exactly is it?

The Chinese version of "Starlink" is accelerating

According to the People's Post and Telecommunications, large low-orbit constellations are aerospace systems that have emerged in the past decade and gradually matured. They are composed of hundreds to tens of thousands of satellites operating in space 300 to 2,000 kilometers above the ground. They currently mainly provide network communication services with shorter latency and larger bandwidth than traditional high-orbit satellites. my country has determined that it will deploy two similar constellations, namely the Qianfan constellation, which has begun construction this time and is supported by Shanghai, and the StarNet constellation coordinated by China Satellite Network Group Co., Ltd.

The technical features of the Qianfan constellation include: the use of flat-panel high-throughput broadband communication satellites, which have the advantages of being close to the ground, low cost, low power consumption, wide coverage, and low latency; providing satellite Internet services with large bandwidth, low latency, high quality, high security, and global coverage.

Qianfan Constellation plans to complete the deployment of 648 satellites in the first phase by 2025, initially building a satellite Internet system with global coverage, with the ultimate goal of providing low-latency, high-speed and high-reliability satellite broadband Internet services to users around the world. The long-term plan of Qianfan Constellation is to deploy more than 15,000 satellites, aiming to provide low-latency, high-speed and high-reliability satellite broadband Internet services to users around the world.

With the gradual construction and improvement of China's large-scale low-orbit constellations such as the Qianfan constellation, China's position in the global satellite Internet field will be further enhanced, and it is expected to provide more convenient and efficient communication services to domestic and foreign users.

Countries are racing to build satellite internet

Looking around the world, more and more commercial companies are launching their own low-orbit constellation plans, including SpaceX's "Starlink", Amazon's "Project Kuiper", Iridium Satellite Communications' "Iridium 2" and OneWeb of the UK. Among them, SpaceX's "Starlink" has launched more than 6,000 satellites, while Amazon's "Project Kuiper" and OneWeb of the UK have also planned to launch thousands of satellites.

It is worth mentioning that satellites need to apply for orbital and frequency band resources to orbit the earth. The principle proposed by the International Telecommunication Union (ITU) is "first come, first served", so orbits and frequency bands are also considered to be a limited and non-renewable strategic resource. Especially in low-orbit space, the number of satellites that can be accommodated is limited, so first-mover countries will have a significant advantage, which is also one of the main reasons for the fierce competition among relevant countries in this field.

So far, my country has accelerated the introduction of a series of policies to support the construction of satellite Internet. In 2020, my country included satellite Internet in the category of "new infrastructure" for the first time, and submitted an application to the International Telecommunication Union (ITU) for a low-orbit constellation and spectrum with a total of 13,000 satellites. To date, the total number of satellites applied for by my country has reached nearly 40,000.
