Recently, my country used the Long March 6A carrier rocket
at the Taiyuan Satellite Launch Center
to successfully launch the first batch of 18 satellites of the Qianfan Polar Orbit 01 group (also known as the G60 constellation)
into the predetermined orbit
The Qianfan Polar Orbiter successfully launched this time Orbital 01 satellites are the first batch of networking satellites of the "Thousand Sails Constellation" program known as the domestic "Star Chain". The complete success of this launch mission is not only a milestone event in the history of the development of China's satellite Internet, but also is regarded as Regarded as the first batch launch of the Chinese version of "Starlink",
marks China's important step in the global satellite
Internet field.
As soon as the news came out, netizens were very excited.
They paid tribute to scientific and technological workers.
That this Chinese version of " What exactly is "Starlink"
?
China's version of "Starlink" is accelerating
According to the People's Post and Telecommunications, large-scale low-orbit constellations are a space system that has emerged and gradually matured in the past decade, consisting of hundreds to tens of thousands of satellites operating in space 300 kilometers to 2,000 kilometers above the ground. It is composed of satellites and currently mainly provides network communication services with shorter delay and larger bandwidth than traditional high-orbit satellites. Our country has determined that it will deploy two similar constellations, namely the Qianfan Constellation, which has started construction this time and is supported by the Shanghai Municipal Government, and the StarNet Constellation, which is coordinated by China Satellite Network Group Co., Ltd.
The technical features of the Qianfan constellation include: using 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 large bandwidth, Satellite Internet service with low latency, high quality, high security and global coverage.
Qianfan Constellation plans to complete the deployment of the first phase of 648 satellites by 2025, and initially build a satellite Internet system with global coverage. The ultimate goal is to provide low-latency, high-speed and high-reliability satellite broadband Internet services to global users. 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 status in the global satellite Internet field will be further enhanced, and it is expected to provide more convenient and efficient communication services for domestic and foreign users.
Countries are rushing to build satellite Internet
Looking around the world, more and more commercial companies are launching their own low-orbit constellation plans, including the "Starlink" of the American Space Exploration Technology Company and the "Kuiper" of the American Internet technology company Amazon. Plan", the "Iridium II" of the American Iridium Satellite Communications Company and the British oneweb. Among them, the U.S. Space Exploration Technology Company's "Starlink" has launched more than 6,000 satellites, and companies such as Amazon's "Kuiper Project" and the British oneweb have also planned to launch thousands of satellites.
It is worth mentioning that satellites orbiting the earth need to apply for orbit and frequency band resources. The principle put forward by the International Telecommunication Union (itu) is "first in, first in, first in, first out". Therefore, orbits and frequency bands are also considered to be limited and non-renewable strategic resources. Especially in low-orbit space, the number of satellites that can be accommodated is limited, so the first-mover countries will have a significant advantage. This is one of the main reasons why relevant countries compete fiercely 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 into the category of "new infrastructure" for the first time, and submitted a low-orbit constellation and spectrum application for a total of 13,000 satellites to the International Telecommunications Union (itu). Today, the total number of satellites applied for by our country is close to 40,000.
