    As an independently-developed-and-operated global satellite navigation system, the Beidou satellite navigation system of China is embracing the world with a more open attitude while providing a new choice of navigation services for the world and winning a greater say for China to keep a foothold in the international satellite navigation field.

    The 7th conference of the International Committee on Global Satellite Navigation System (ICG) was recently held in Beijing. The conference gathered some 240 conferees from 16 countries and regions as well as 18 international organizations, and focused on such main topics as compatibility and interoperability, service improvement and capability building of the satellite navigation systems.

    The Beidou system was successfully tried out in Pakistan not long ago. The 16th Beidou navigation satellite of China was successfully launched on October 25, 2012, marking the Beidou navigation system has acquired the ability for regional services.

    According to the plan, the Beidou satellite navigation system will provide full services for most areas in the Asia-Pacific region in early 2013. By 2020 when the Beidou global satellite navigation system has been completed, the 30-plus satellites will provide services covering the entire world.

    Besides its due functions of navigation, positioning and time service, the Beidou satellite navigation system possesses two unique functions of location report and short message communication compared with other navigation systems. The Beidou system, which adopts active and passive satellite navigation and positioning technological setups, has distinct advantages compared with the single passive technological setup of other systems.

    The integration and application of Beidou's function and its technological advantages with mobile communication and Internet can facilitate the seamless positioning and connection both indoor and outdoor to provide all-day services for users, which is of great application value in developing smart cities and the Internet of Things.

    The competition in satellite navigation field is not a zero-sum game where "I win or you win". The Beidou satellite navigation system does not only belong to China, but the whole world as well. China is willing to work together with the other countries to share the development achievements of satellite navigation, jointly formulate standards, enhance compatibility among multiple systems, extend service fields and promote the extensive application of satellite navigation worldwide

    China's contribution to humanity. Our great founding father, Chairman Mao ever said, "we should ask ourselves, what has China done for the people of the world, for human being's progress?", he won't be disappointed.

    Are you kidding me? The navigation system is described as "independently operated"-God only knows what this means, considering the report is from a Chinese military site and the only place (other than China) where it has been tested is the rogue/failed Islamic Republic of Pakistan.

    Who in their right mind will develop any consumer device based on this noodle system? Do you really think anyone trusts the Dictatorship of China?

    "Location report" is unique to Beidou? Really? Do these idiots even understand what a navigation system is used for? An SMS is a good reason for the world to switch from GPS to your noodle system? :crazy:

    Beidou = Triones. just like Chaireman Mao, guides human.
    wondering when will it become so cheap that even Aman2REP can not help himself to buy one.

    For civil use, Beidou doesn't stand a chance so far in global market; but for military use, Beidou gives the potential customers an alternate to American GPS. People like multiple options, not every one hopes their missile can only be guided by American GPS.

    That is what's I most hate CCP part. they waste a lot of money. they should think about civil use such as
    AC BBQ , baseketball just like US and India do.

    Do the Chinese have their own constellation of satellites? How accurate it is going to be? if people want an alternative to American GPS they can always go for the Russian GLONASS. For civilian use GPS/GLONASS combined is the best.

    yes, we do, yesterday we just launched our 16th, for the years coming, we will continue to complete this constellation, the first phase is a 32 satellite system.

    very precise, for military signal, let's use a famous example, we won't hit your dresser if we aimed at your bed.
    for civilian use 10 nano second, 20 meter horizontal accuracy.

    GLONASS will be more accurate than Beidou anyday.

    Not necessarily true. Accuracy is based on the location of the signal coverage and signal strength.

    Beidou covers asia pacific, with a focus on east and south China sea, the PDOP value varies from 2.0 to 3.0, Glonass also 2.0 -3.0
    GPS is more accurate around 1.0-1.5, this is civilian signal.

    Beidou uses two way communication, active/passive linkage to satellite, it has more future than one way passive receivers,
    this aside, with the improvement of our atomic clock, Beidou will surpass Glonass' accuracy globally in near future.

    08 Wenchuan, rescue workers uses Beidou as a GPS and a Satellite phone. because it can send short message in an area wireless signal is down.

    All our deep sea fishing boat has beidou on it, last time when Philippine armed police tried to arrest our fishermen, they used Beidou to notify our MS boat, and got saved.

    Of course, China has its own satellites constellation, otherwise how could Beidou provide positioning services? Beidou navigation system isn't a project on paper, China has finished the second stage in the building the whole system, sending 16 satellites into the orbits in total, enabling Beidou signal to be received in Asia-Pacific region.

    I can't say the Beidou's accuracy is better than Amercian GPS or Russian GLONASS because Beidou systen is still at the early stage of its development, But accuracy doesn't really matter as long as the accuracy is acceptable, when people are looking for an alternate. And more importantly, the system can be perfected and its accuracy will be improved as it is getting mature.

    So far, there are a dozen of countries showiing interest in Chinese Beidou system, especially as Chinese defence industry is developing weapons integrated with Beidou system, China is gonna sell the weapons and the positioning service as a package, that is the best way to promote Beidou.

    i doubt that, if Russians stop upgrading the system fast enough, it is just a matter of time for them to be surpassed.

    One thing interesting to mention is as early as in 2007, India has planned to build up its own global positioning system and claimed it will use 6 years to set up an initial GAGAN system, which will compose 6 satellites and EuroSpace is the contracted launching service provider, now, we are one month short of this scheduled 6 year, there is still no GAGAN in anywhere.

    Galileo is fading out too, because Chinese have the money to launch their satellites and the channels are limited.

    In the future you will only see three major systems of global positioning services, the competition between these three will greatly benefit mankind's progress

    China's achivements are dedicated to CCP's brnefits and never aimed at the benefit of mankind and the rest of the world. It does not care about the envirorment. China just knows how to brag!

    GAGAN (means "sky" in Sanskrit):

    GPS-aided geo-augmented navigation - Wikipedia, the free encyclopedia

    Gagan was intended for civilian use, as India cannot depend on GPS for its missile targeting systems. For that, India is developing the IRNSS:

    Indian Regional Navigational Satellite System - Wikipedia, the free encyclopedia

    India doesn't need a "global" positioning system because its only adversaries are China and Pakistan. For them, IRNSS is enough. In the future, India may elect to test ICBM's and hence expand the IRNSS to have a global footprint.

    Besides, if it comes to weapons sales, I'm sure most countries in the Asia-Pacific would trust the Indian IRNSS rather than Beidou.
