China to launch fifth orbiter for its own 'GPS' - People's Daily Online July 31, 2010

China will launch its fifth orbiter into space, as part of its satellite navigation and positioning network known as Beidou, or Compass system, in the next few days.

An official with the Xichang Satellite Launch Center, in southwestern Sichuan Province, who is not identified, said Friday that the satellite would be launched on the Long March 3I carrier rocket in the coming days, adding that it would take place "at a proper time".

If launched successfully, the satellite will join four other satellites in orbit to form a network that will eventually consist of 35 satellites.

China started building its own satellite navigation system to end its dependence upon the U.S. GPS system in 2000, when it sent two orbiters as a double-satellite experimental positioning system.

Beidou, as the system is called, is designed to provide navigation, time and short message services in the Asia and Pacific region in about 2010 and will be capable of providing global navigation services by 2020.

China Radio Reports Plans for Another Compass/Beidou Launch Soon | Inside GNSS

China Radio International (CRI) reported today [July 30, 2010] that China will launch its fifth Compass/Beidou-2 orbiter within the next few days. An unnamed official with the Xichang Satellite Launch Center in southwestern Sichuan Province said Friday that the satellite would be launched on the Long March 3I carrier rocket in the coming days.

If launched successfully, the satellite will join four other satellites in orbit to form a network that will eventually consist of 35 satellites.

China Radio International (CRI) is the only overseas broadcaster in the People's Republic of China and is owned and operated by the state.

Awesome news!!!Great job done by the Chinese.I hope common people will be able to access the services just like the GPS.

what is own 'GPS' ???

Awesome news!!!Great job done by the Chinese.I hope common people will be able to access the services just like the GPS.

there will be free civilian access like all other planned/existing gps network, however there is also a military side, where it provides better accuracy etc.

 

[azfar]

in future what kind of devices people need to benefit form this service? are current navigation devices configurable to change the service provider?

 

[ao333]

Yes, the coding and frequencies for all (American, European, Russian and Chinese) Global Navigation Satellite Systems are compatable with current devices (CDMA; E1-6).

Russia adopted a different coding and frequency methodology during the Soviet era, so as to deter attempts at code-breaking and interfering/jamming the transmission for security purposes. Commercial use wasn't a goal for Russia (nor was it for the US until 1997); consequently, there wasn't much effort put into globalizing the systems.

However, post-Soviet era saw Russia commercialize many of its industries, including satellites. As such, just recently, Russia began developing CDMA, to break into the global market, though they have not abandoned FDMA.

In spite of uniform coding, there is a problem of frequencies. It would appear that China and Europe are in a war over E1,2,5B,6 bands which may result in China's victory. If so, then Europe's system will cost significantly more as an overhaul of the system will be mandated.

For us consumers, the more the marrier, since newer chips carry the ability to combine signals from more than 1 satellite to greatly increase accuracy and receive signals from all bands, thus portable devices such as I Phones and navigators will be able to use any service from any system interchangeably.

i think it is one step towards a male UAV>

 

[RAHUL INDIAN]

congrats to Chinese.

 

[Gin ka Pakistan]

So many Satellites circling around the earth and many are at the end of their life cycle and need to be replaced soon else say good bye to GPS in ten years

 

[CardSharp]

what is own 'GPS' ???

own = China's self-made.
GPS = Global Positioning System.

Global Positioning System uses the frequency shifts from multiple satellite to locate one's position on earth.

I wish we can also get off the internet/navigation stuff like GPS on Pakistan's own network or thru chinese networks

China launchs fifth orbiter for its own GPS - People's Daily Online August 01, 2010

The fifth orbiter into space, as part of its satellite navigation and positioning network known as Beidou, or Compass system, is launched on the Long March 3I carrier rocket at Xichang Satellite Launch Center in Xichang, southwest China's Sichuan Province, on August 1, 2010. (Xinhua/Du Cai)

XICHANG, Aug. 1 (Xinhua) -- China successfully launched its fifth Beidou into space at 5:30 a.m. Sunday, as a part of its indigenous satellite navigation and positioning network.

The satellite was launched from the Long March 3I carrier rocket.

It is the 126th flight for the country's Long March series of rockets.

The satellite will join another four satellites in orbit to form a network that will eventually consist of 35 satellites.

The system, code named "COMPASS", is a crucial part of the country's space infrastructure for providing navigation and positioning services in transportation, meteorology, petroleum prospecting, forest fire monitoring, disaster forecast, telecommunications and public security among others.

China started building its own satellite navigation system to end its dependence upon the U.S. GPS system in 2000, when it sent two orbiters as a double-satellite experimental positioning system.

The system is designed to provide navigation, time and short message services in the Asia and Pacific region before 2012 and will be capable of providing global navigation services by 2020.

3 beidou satellites launched successful in 2010 till now
