Beidou diagram

BD is generally considered a " global satellite navigation system " , but in fact he is a "global space communication switching network system " , referred to as "space the Internet . " Navigation is just part of his functions , the Internet space in China in fact has been a world leader in the field , the system is in geostationary orbit satellite is the core of the exchange , every continent generally have a regional exchange of stars, so the relative amount of the Big Dipper Other systems should be more . Days chain is deep-space satellite communications satellite , the system is interconnected with the Big Dipper .

China's recent transformation of the early-warning aircraft , electronic intelligence ship, Yuan Wang tracking ship and aircraft carrier Dengjun future of the Earth as Beidou mobile switching station , for local exchange capacity to strengthen communication and sensing . Other functions are China's satellite network system can be connected to the Big Dipper , as vanguard reconnaissance satellites , meteorological situation and so what has the real-time information transmission. Chinese Air Force 's " Air and Space Integration " rhetoric , the most fundamental is that because of the Compass system .

Compass is the use of the East Red communications satellite reforms, built an ATM switch , if a pure no need to use satellite navigation satellite so large , but also so we can see why the Big Dipper Unlike other navigation satellite launch as a place like eggs Several of the , you know China's multi-satellite is the story already .

Compass features a short message just proved that he is a two-way satellite communication capabilities , but limited only to the individual terminal traffic fills can be as long as he is willing to open broadband to the specific terminal . Sun Jiadong said: Compass in China 's short messaging navigation satellites for other countries can not do . In fact, the system that covers the white of the Compass navigation system , while far from being a pure navigation system !

Chinese people imitate and re- raise , Compass once again embodies the characteristics of the Chinese people 's wisdom and . China's scientists and policy makers to steal a name change and enlarge - " navigation satellite ! " Model with global navigation satellite structure of the world's first "space communication switching network . "

Compass global information system in China in the field of a major base system , its far-reaching ! Compass system with China's military capacity has been qualitative improvement , is no exaggeration to say that from the Chinese military has a global fighting . China's military equipment in future systems and technology system will join the Big Dipper as the building blocks of the same system . China's space system to a system of innovation, and real space communications to walk in the world. Cheers again for the Big Dipper !

To break the monopoly of satellite navigation

Navigation satellites in succession in place , marking China's " Compass "system to maturity and expanding into network construction has been "fast-track . " Ph.D., University of Wollongong, Australia , aerospace experts莫里斯琼斯In an interview with Australian Broadcasting Corporation interview that China's development of an independent global satellite navigation system , is to get rid of dependence on U.S. technology . Jones said, "We use the GPS system has been in the grip of the U.S. government , when it comes to the military aspects, such as in war , the United States can terminate their services at any time . For China and most other countries , the development does not depend Independent system in the United States is important . "

The outside world that China's space industry is developing steadily in the background, " Compass "navigational system is bound to usher in the golden period of development ; contrast, the U.S. space program has emerged , " interrupted . " Jones pointed out that " the United States is a large-scale compression space projects , not even in the near future astronauts into space, the independent ( cause the shuttle retired ) ; and steady development of China is a large number of national space projects , according to current trends, China Will be able to challenge U.S. space dominance . "

Some analysts believe that China's development , " Compass "navigational system, first of all is to meet its economic and military needs in the area , of course, to international users with more choices , to some extent actually played against a State monopoly of the role of satellite navigation market .
