Two more satellites. China Expands Beidou-3 Navigation Network

China continues to expand the space grouping of the domestic satellite navigation system. According to the Chinese Aerospace Science and Technology Corporation of China (CASC), on Wednesday, China put two Beidou-3 navigation satellites into orbit.


Two more satellites. China Expands Beidou-3 Navigation Network


The successful launch of the Changzheng-3B and Yuanzheng-1 launch vehicles took place on Wednesday from the Xichang cosmodrome in Sichuan province in southwestern China. Two navigation satellites of the Beidou-3 type have become the 37-m and 38-m satellites of the global navigation system Beidou, created by China. Both of them went into a given orbit and are waiting for testing, after which they will join the main network and will work with previously launched Beidou satellites. Currently, the Beidou-3 system (global, created simultaneously with the national Beidou-1 and the regional Beidou-2) has 14 satellites.

In total, by the end of this year, China plans to increase the number of Beidou-3 satellites put into orbit to 18, and by the end of 2020, bring them to 35, thereby completing the formation of a global network.

Today, the Beidou-3 network covers the entire territory of the country and part of the Asia-Pacific region, and by the end of the year, China plans to start providing basic navigation services to countries along the new Silk Road. After the final formation of the satellite constellation by the end of 2020, the services of the Chinese navigation system are planned to be provided worldwide.

    A proposal to unite GLONASS and BeiDou to the "Roskosmos" was addressed by the Chinese side - the State Commission on Navigation Satellite System. It is intended to “create a unified system for monitoring global navigation satellite systems operating in the space of the Shanghai Cooperation Organization”.


    Those. they refused the idea of ​​unification chtol ... ???

    Successful launch of Changzheng-3B and Yuanzheng-1 carrier rockets

    The translation is not quite right, Yuanzheng-1 is not a rocket, but a payload output unit, it was just installed on Changzheng-3B

      Yes, they all look alike.

    The new Lexus already has its own navigation, nichrome is not clear. Soon, each country will have its own navigation.

    And why should the PRC actually need to combine its BeiDou with Glonass?
    We cannot do new satellites without Western components on our own; what is flying now is gradually failing
    https://lenta.ru/news/2018/04/25/glonass/
    Or it is not put into orbit, as in the case of Proton-M and 3 Glonass satellites, which fell.
    PS: Is China giving us access for no reason?

      To increase accuracy, it depends on the number of satellites.

      For civilian use, maybe yes.

      Navigation along the Northern Sea Route, along which China brings goods to Europe 1/3 faster than via Suez, navigation on the Silk Road ... They all need it desperately, and they don’t have Chinese satellites there - so they will give, and they will pay extra

    You intentionally misrepresent the facts:

    1. As for the “give access”, it would be the opposite: now Glonass works all over the world, but when Beidu is working, he has only plans, in practice he works only in China and partially in Southeast Asia.

    2. All satellite constellations of any countries must be updated, because the satellites are gradually failing, and unsuccessful launches occur with any space powers. You can see statistics on the Internet.

    3. The whole world uses electronics developed in the USA, mainly, and in a number of other countries, and manufactured in Asia. Replacement with its elemental base is gradually occurring, but it cannot happen either in a day or in a year, because it is impossible to compress the decades spent on its development in a year or two, or three. You can optimize the process, but you will have to spend about the same amount of time or find radically different solutions, they will not increase in any way from whining.

    Bottom line: stop lying and carry nonsense, there is no kindergarten.

      As for the "give access", it would be the opposite: now Glonass works around the world, but when Beidu works, he has only plans, in practice he works only in China and partially in SEA.

      Glonass does not work around the world. Read the article why.
      Bottom line - do not pi .. lie. And first read at least something, except for "murzilka".

      The whole world uses it, but we have sanctions. In electronics and element base, I know many times more than yours. Profession. And I’ve been doing this since 1996.
      We will not come close to Intel's technological processes, even if we still buy a couple of factories in Taiwan.
      Total Now - we CAN’t do satellites. Only in Chinese (Southeast Asia) kit. If they sell.
      Can optimize the process

      What process is it not to cook dumplings, and not to flabby pivasika. Do not carry nonsense, like Rogozhkin. There are many things we do not know how and will not learn soon. And diesel engines for the Navy, and GTA there too ... what year we have been doing, but things are still there. And the "motor switch" has not been replaced, and civil engines for airplanes, only one in 30 years we have been certified.
      The bottom line is not "whining" but facts. And don't be rude, kid from "kindergarten"

    GLONAS stations (for differential correction) in 2017 installed 8 pcs. abroad:
    4 in Brazil, 3 in Antarctica, 1 in South Africa.
    It is planned for 2018 in: Kazakhstan, Belarus, Armenia, Argentina, Cuba, Ecuador, Venezuela, Mexico, Sweden, Vietnam, India, Indonesia and China.
    Chinese will be used jointly by Beidou and GLONAS
    The United States refused us, in response we remove them on our territory.

    “On February 26, the first GLONASS-K satellite of the third generation was launched with improved accuracy characteristics and an active life of 10 years.
    On October 3, the Glonass-M spacecraft was launched into orbit. The deployment of the orbital constellation of the GLONASS global positioning system has been completed.
    On October 26, the Glonass-M spacecraft launched on October 3 was put into operation ”(http://www.nis-glonass.ru/about-glonass/history/)

    From that moment, Glanass began to work globally.

    Listen, "electronics specialist," you’ve already rolled down, or you may have.
    Are you aware that in the solutions issued today by the main manufacturers Qualcomm, Exynos, Broadcom there is a definition of coordinates by Glonass? If it hadn’t worked globally, as you say (I don’t know how a professional in the field of electronics can say this at all), this would simply never have happened. Such statements are below the level of not a specialist, but the average human level of development of the adult population. For whom, then, are your scribbles, for the audience of Navalny and co?
    Next, read at least a mursilka with pictures, if you can’t in English, about the “donated access”. Beidu for today is a regional project, see map (http://gpsworld.com/gnss-the-new-gps/):

    Now - WE CAN NOT do satellites

    Are you okay?
    Another Glonass satellite launched in June.

    Only in Chinese (Southeast Asia) kit. If they sell.

    The whole world works on the “Chinese komplektuhi”, because they threw off their production. In addition, you are not a developer of spacecraft, to know their structure, stop already hanging noodles on your ears.
