China to establish global satellite navigation system by 2020

A senior space technology expert in China said the country's global satellite navigation system, which is composed of more than 30 satellites, is expected to be in place by 2020.

China would launch 12 to 14 satellites during the early part of the 12th Five-Year (2011-2015) Program, said Qi Faren, former chief designer for Shenzhou spaceships, during an exclusive interview with Xinhua Tuesday.

China started building its own satellite navigation system in 2000 and had set up a regional satellite navigation system after launching three Beidou geostationary satellites between October 2000 and May 2003. Beidou is the Chinese pinyin of compass.

"The Beidou-1 regional navigation system played an important role in the rescue efforts following the devastating earthquake in May 2008 in Wenchuan as it provided the only channel connecting the quake-hit area and the outside," he said.

The Beidou-1 system can not meet growing demand, so a better functional Beidou-2 regional and global navigation system will be set up in two stages, said Qi, who is also a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC).

Between the early part of 2011-2015 period, 12 to 14 navigation satellites will be launched to provide navigation, timing and short message services in the Asia and Pacific region. By 2020 a global navigation system comprising more than 30 satellites will be in place, he said.

As of December 2010, China had launched seven satellites for the indigenous Beidou positioning network.

"The Beidou-2 system can be taken as the China-made GPS which can be applied wherever the U.S. GPS operates," said Qi, adding that the system can play a key role in forecasting earthquakes, defining borders more precisely, guiding lost drivers and ensuring accurate military operations.

Chinese drivers would benefit from the Beidou-2 system since the U.S. GPS is currently the dominant provider of navigation services for vehicles in China, said Qi.

Could be much sooner. As early as 2016.

[DesiGuy]

2020....??

can it be done little early?

Maybe, things like this are usually ahead of schedule in China.

We shall see.

[StingRoy]

Must be a good news for the GPS makers... Russia, India and China announcing their own satellites navigation systems.

[ephone]

Russia has its GPS-type system already and just started new upgrade. I think China can get it done before 2020. We are always modest in such estimation.

BTW, what is India's schedule for GPS? No offense, it seems that India is behind schedule most of the times.

Operationally, it just has to cover North America, Asia, Pacific and Indian Ocean, which means it will serve 80% of its purpose after the first 14 satellites in 2011 to 2014. I'm sure China will prioritize the launch sequence based on military considerations. There's no urgent need to cover the Atlantic Ocean, South America or Africa.

2015 is about the right time.

In this case, Indian ones are the Russian ones. India pay some money and claim the Russian GLONASS as their own as India do not even have a plan for launching their own global naviagion system. Even their regional test system has been delayed indefinitely. So that is why likeT-50 and many other systems, they latch on to the Russia technology.

Satellites will start launching end of 2011 and full system operational targeted by 2015

It was a bit strange you mentioned that India started navigational systems before China. Beidou 2 already has 6 satellites in space.

First of all, these seem to be a regional test system. Even as a regional system, the first satellite has not been launched yet.

[Andross]

The Indian Regional Navigational Satellite System (IRNSS) is an autonomous regional satellite navigation system being developed by Indian Space Research Organisation which would be under total control of Indian government.

The government approved the project in May 2006, with the intention of the system to be completed and implemented by 2014. The first satellite of the proposed constellation, developed at a cost of Rs.1,600 crore (16 billion rupees), is expected to be launched in last quarter of 2011.

A goal of complete Indian control has been stated, with the space segment, ground segment and user receivers all being built in India.
It is unclear if recent agreements with the Russian government to restore their GLONASS system will supersede the IRNSS project or feed additional technical support to enable its completion. However reports came in Apr 2010 that India plans to starts launching satellites by end of 2011 and six months periodic launches take place. It means the IRNSS optimally functional by 2014

The navigation signals themselves would be transmitted in the S-band frequency (2–4 GHz) and broadcast through a phased array antenna to maintain required coverage and signal strength. The satellites would weigh approximately 1,330 kg and their solar panels generate 1,400 watts.

The System is intended to provide an absolute position accuracy of better than 20 meters throughout India and within a region extending approximately 2,000 km around it.

The ground segment of IRNSS constellation would consist of a Master Control Center (MCC), ground stations to track and estimate the satellites' orbits and ensure the integrity of the network (IRIM), and additional ground stations to monitor the health of the satellites with the capability of issuing radio commands to the satellites (TT&C stations). The MCC would estimate and predict the position of all IRNSS satellites, calculate integrity, makes necessary ionospheric and clock corrections and run the navigation software. In pursuit of a highly independent system, an Indian standard time infrastructure would also be established.

Agree... corrected my post. Wasn't aware that China had already started launching the satellites for the Beidou2.

Don't worry I didn't know until recently.
