Thick accumulation and thin hair! Beidou system began to provide services, and Hongyun Project will establish a space-based Internet.

Tsiolkovsky, the father of space flight, predicted that "the earth is the cradle of mankind, but mankind cannot be bound in the cradle forever".

In fact, space flight is not only related to the future of mankind as a whole, but also a dream of China people for thousands of years.

With the approach of 20 18, when we look back on the space journey that China has taken this year, we will find such a long report card:

As of February 27th, 18, China completed 38 rocket launches in 20 18, and the 296th flight of Long March series launch vehicles was also completed, including:

18 Beidou-3 satellites were successfully launched and networked;

Remote sensing satellite 30 04,3101was successfully launched;

In 2002, 2003 and 2004, Gaofen No.1 star, Gaofen No.5, No.6 and No.11 were successfully launched;

Gaojing 03 and 04 satellites were successfully launched, and the first batch of networking was completed with 0 1 02 satellites launched on 20 17.

The Chang 'e-4 relay satellite "Queqiao" and Chang 'e-4 detector were successfully launched;

Successfully launched Fengyun-2 H star, and made observation with Fengyun-2 E, F and G stars in orbit;

Haiyang-1 star C and Ocean-2 star B were successfully launched;

Land exploration satellites 3 and 4 were successfully launched.

And 20 18 is also the first year of commercial space development in China. Private companies in China have achieved a breakthrough from 0 to 1 in the aerospace field, and their commercialization attempts in the aerospace field have also taken substantial steps. For example:

On May 17, "Zero One Club" successfully launched China's first private suborbital commercial rocket.

On October 27th, 65438/KLOC-0, Suzaku-1 solid carrier rocket developed by "Blue Arrow Aerospace" was launched. Although the launch failed, it was the first orbital launch by a private company in China, which was of great significance.

On February 7th, 65438, several satellites developed by Changsha Tianyi Research Institute were successfully launched.

Among the achievements of the 20 18 space launch, the most exciting is the successful deployment of the Beidou-3 basic system constellation. With the successful launch of 10, the successful launch of 18 Beidou satellites and the successful networking of 19 Beidou satellites, Beidou navigation system has successfully taken a "key step" from regional to global.

However, just as "Rome was not built in a day", the success of Beidou-3 global navigation system cannot be separated from the background of the whole Beidou system.

Shen Yuan, deputy commander of Beidou navigation satellite, mentioned in his inaugural speech that Beidou satellite navigation system has experienced three stages: Beidou-1, Beidou-2 and Beidou-3.

Starting from 1994, China began to build Beidou-1. Through continuous iterative upgrading, Beidou-2 was completed in 20 12, and the regional system construction of Beidou system was steadily realized.

Beidou-3 released a white paper in 20 16, and completed its first launch in 20 17. At present, it has completed the networking of 19 satellites, basically achieving the development goal from regional to global, and will eventually complete the networking of 35 satellites in 2020, becoming the four major global positioning systems alongside American GPS, Russian GLONASS and European Union Galileo.

According to Shen Yuan, compared with the previous Beidou-1 and Beidou-2, Beidou-3 has greatly improved its service scope, aerospace capability, compatibility with other global systems and accuracy, and can provide high-precision and high-reliability positioning, navigation and timing services for all kinds of users around the world.

Even compared with the other three global navigation systems, Beidou-3 has unique advantages in inter-satellite link technology, autonomous navigation capability, on-orbit reconstruction and on-orbit empowerment technology.

"20 18 is the first year of commercial aerospace. Commercial launch, space tourism and the integration of heaven and earth all have huge business opportunities, which will be a trillion-dollar market. When all conditions are met, the favorable space for commercial aerospace will come and countless unicorns will be born. "

In June 5438+ 10 this year, Liang Xiaohong, former party secretary and vice president of China Academy of Launch Vehicle Technology, predicted in his speech that the next outlet would be commercial aerospace. Private companies entering the aerospace field can be roughly divided into: satellite companies, rocket companies, measurement and control companies and so on. In reality, there will never be a shortage of pioneers who dare to eat crabs first.

For example, the bosses of Zero One Club, Blue Arrow Aerospace and Tianyi Research Institute, Shu Chang, Zhang Changwu and Yang Feng of these private aerospace companies were interviewed or gave speeches on 20 18.

Launch vehicle is the basic tool for satellite flight. Zhang Changwu, CEO of Blue Arrow Aerospace, said that the launch fuel, reusable technology and commercialization prospects of rockets must be considered by private companies.

Medium-sized launch vehicle is the only rocket sequence that can support the future low-orbit launch market. In his view, the combination of liquid oxygen and methane will be the most economical, environmentally friendly and practical rocket propellant.

2065438+081October 27th, 18, Suzaku-1 solid carrier rocket developed by Blue Arrow Aerospace was launched. Although it was not successful, it was the first in-orbit launch of a private space enterprise in China, and it is not an exaggeration to say that it is a milestone in the domestic private space industry.

In the past, the space industry was a national-level space competition, which was time-consuming and laborious. But as Yang Feng, CEO of Tianyi Research Institute, said in his speech, a "microsatellite" method has been adopted in the space field. It only takes 1 year or even less time and millions of funds to realize the space achievements that used to take1year and cost hundreds of millions.

This small step-by-step approach to space exploration is not only steady, but also creates a very realistic operability for private companies to enter. On February 7th, 65438, many satellites developed by Tianyi Research Institute where Yang Feng was located were successfully launched.

According to the plan, Hongyun Project will launch 156 satellites to establish a global space-based Internet covering the Antarctic and Arctic in space. In layman's terms, it is to let users access WiFi without dead ends on a global scale. Undoubtedly, this project will provide services for unmanned driving, Internet of Things, air transportation, ocean engineering and many other industries that need seamless connection of global networks in the future artificial intelligence era, and will also provide huge imagination space for private space flight.
