CCTV News recently reported that China’s first space-based Internet system “Hongyun Project” will be put into demo applications in 2020. According to the introduction, the space-based Internet, is to put our usual use of the Internet into space. It is based on more than 100 Internet satellites in orbit 1000 km above the ground and, when completed, will enable global Internet access, covering areas beyond the reach of ground communications such as 5G.
When completed, people will be able to access broadband Internet in any corner of the world, enabling web browsing and HD video anytime, anywhere.
According to public information, Hongyun Project is one of the five commercial space projects of China’s aerospace science and engineering, aiming to build a low-orbit broadband communications satellite system covering the whole world. At the end of last year, China Aerospace Science and Technology Group successfully launched the first satellite of the Hongyun Project at the Jiuquan Satellite Launch Center. The satellite successfully entered its intended orbit through the Long March-11 carrier rocket.
According to the plan, the Hongyun Project will launch 156 satellites. The entire Hongyun project is broken down into three steps of “1 plus 4 plus 156”, the first step of the program to launch the first technical verification satellite, to achieve the single-star key technology verification. Finally, at the end of the 14th Five-Year Plan, all 156 satellite networks were realized and the business constellation was built.
The space-based Internet sounds very aggressive, so how is this project going now?
Elon Musk, chief executive of SpaceX, used the Starlink satellite to send his first tweet on October 22, US time.
“This tweet was sent via starlink satellite,” Musk tweeted. Then he posted a message saying, “Wow, it worked.” ”
To date, the fastest-growing and largest space Internet project is SpaceX’s “starlilnk.”
In January 2015, Musk announced that SpaceX plans to launch about 12,000 communications satellites into orbit, 1,584 of which will be deployed in near-Earth orbit 550 kilometers above Earth and will begin work in 2020. This is the ambitious “Starlink” plan.
On May 23, 2019, SpaceX took an important step toward building the global satellite Internet by successfully putting the first 60 satellites of the StarLink into orbit using the Falcon 9 launch vehicle.
In July, SpaceX sent its first 60 satellites into space, and musk said that when the number of satellites reached 400, the “starlink” network would have “smaller” coverage, while the “available” state would require at least 800 satellites.
SpaceX is planning to officially offer space broadband services to users in the U.S. by mid-2020, Space News reported. To achieve that goal, SpaceX will need to complete 6-8 launches, each carrying 60 broadband satellites into near-Earth orbit, said Gwynne Shotwell, the company’s chief operating officer.
These satellites will operate on different orbital planes and communicate with each other to form a network, with the ultimate goal of providing users in any region of the world with a maximum speed of 1Gbps bandwidth.
At present, the number of satellites approved for the entire Starlink project has reached 12,000, far higher than expected. Not long ago, SpaceX filed a new application with the International Communications Union for a communications license for an additional 30,000 satellites.
If they all pass the application, it means that more than 40,000 “starlink” satellites will be in low-Earth orbit in the future, knowing that there are currently fewer than 2,000 satellites currently operating in orbit around the world. If SpaceX can stick to this plan, the number of “starlink” satellites in two years will be far greater than the sum of all the satellites currently launched by humans.
SpaceX estimates that by 2025, the space Internet service built by the Starlink project will generate about $30 billion in annual revenue for the company, and will help SpaceX’s own rocket launch business.
Musk is bullish on the starlink’s earnings prospects. He believes the “starlink” will capture 3 to 5 percent of the global telecommunications market, with annual revenues of $3 trillion. “We believe this is a way for spaceX to generate revenue and will fund the development of increasingly advanced rockets and spacecraft,” Musk said.
Similar to SpaceX’s “starLink” is the “Hongyun Project” of China Aerospace Science and Technology Group, compared with the “Starlink” project, “Hongyun Project” project is smaller, it plans to launch 156 satellites, 1000 kilometers above the ground in orbit, to build a global network. By the end of 2018, the first test satellite of the Hongyun Project had been successfully launched.
At present, Hongyun’s first star is running well in orbit, the space-ground connection test is under way, and on July 9, 2019, more than 10 first-star developers were the first experience users to conduct WiFi networking on site. people turn off 4G signals and log on to WiFi hotspots at satellite user stations. With the entry of satellites, people have successfully connected to the Internet, and jointly experienced high-definition video calls, high-definition video-on-demand, web browsing, mail delivery and other multimedia services.
When constellations are deployed in 2022, Hongyun Engineering will be able to provide a seamless global coverage of broadband mobile communications services, for all types of users to build a “through the remote” integrated information platform.
With its very low communication latency, very high frequency multiplexing rate and true global coverage, Hongyun Project can meet the needs of China and the underdeveloped internet regions, large-scale user units sharing broadband access to the Internet at the same time. At the same time, it can also meet the application requirements of emergency communication, sensor data acquisition and industrial Internet of Things, remote control of unmanned equipment, etc. The targeting of the user group is mainly cluster user groups, including aircraft, ships, passenger and cargo vehicles, field areas, operations teams and some remote villages, islands and so on. Drones, the driverless industry, etc. are among the industries that Hongyun Engineering may serve in the future.
In addition, in addition to the “Hongyun Project” of aerospace science and technology, China’s other large space group- China Aerospace Science and Technology also has its own low-orbit communications project, called “Hong Yan.”
The constellation is expected to complete the construction of a phase of 60 satellites in orbit by 2022, which will directly serve the Belt and Road region. The second phase will expand to more than 300 satellites, expand broadband services to the world, to serve 2 million mobile users, 200,000 broadband users and nearly 10 million Internet of Things users, and to provide integrated services in navigation, aviation, navigation and other fields.
That is to say, the constellation of 60 satellites in the first phase of Hung Yan is called the “Mobile Communication Constellation”, which gives priority to the ability to make calls, and after the completion of the second phase, a “broadband communication constellation” will be added to solve the Internet access function. The entire program is completed after 2024.
