At the press conference of the State Council Information Office held on the afternoon of December 27th, the director of the China Satellite Navigation System Management Office and the Beidou satellite navigation system spokesperson Yu Chengqi announced:

The construction of the basic system of the Beidou No. 3 was completed and began to provide global services today. This marks the expansion of the Beidou system from regional to global, and the Beidou system officially entered the global era.

According to reports, the Beidou system is a global satellite navigation system that is independently constructed and operated independently by China and is compatible with other satellite navigation systems in the world. It can provide high-precision and high-reliability positioning for all kinds of users on a global scale, all-weather and all-day. , navigation, timing service.

Since the 1990s, the Beidou system has been developed and developed according to the "three-step" development strategy. It is first active and passive, first regional and global, and has built Beidou-1, Beidou-2 and Beidou No.3 systems. A road for the construction of satellite navigation systems with Chinese characteristics.

Dalintai - a herder in northern China - used to travel miles every day on his motorcycle to deliver water for his livestock.

Now, according to the the Xinhua news agency, all he has to do is send a text message to operate an automated water delivery system.

"I am able to deliver water to my sheep and cattle wherever and whenever I want via this system," he says.

The message is relayed over China's expanding Beidou satellite navigation system, which is already being used used for transport, agriculture and even precision missiles.


Originally designed for the Chinese military to reduce reliance on the US-owned GPS, Beidou has turned into a commercial opportunity as its coverage has expanded.

Last month, local authorities ordered 33,500 - about half of all taxis - in Beijing to install Beidou, and the Chinese government has set a goal that all new cars will be Beidou-guided by 2020.

Domestic phone brands such as Huawei, Xiaomi and OnePlus are now Beidou-compatible, although Apple did not add the Chinese system to its new line-up of iPhones announced on 12 September.

China is increasingly keen to promote its technological prowess to the rest of the world.

Yang Changfeng, the system's chief designer, has been vocal about his country's ambition to attract more overseas clients.

"China's Beidou is the world's Beidou, and the global satellite navigation market is certainly Beidou's market," he told Global Times last year.

'Space Silk Road'
Named after the Chinese word for the Big Dipper or Plough constellation [Ursa Major], Beidou has been in the works for over two decades but only became operational within China in 2000 and the Asia-Pacific region in 2012.

When complete in 2020, it will have a constellation of 35 satellites to provide global coverage. This year alone, there have been more than 10 Beidou satellite launches - two more were launched this week. More are planned in what state media describe as a "period with unprecedentedly intensive launches".

By the end of 2018, it will cover countries along the Belt and Road Initiative (BRI) - a massive China-led infrastructure and trade programme, part of what it calls the "Space Silk Road". Beidou already covers 30 countries involved with the BRI, including Pakistan, Laos and Indonesia.

"There is certainly an aspect of this that is about expanding influence, but part of it is likely also about economic security," Alexandra Stickings, from the Royal United Services Institute for Defence and Security Studies, tells the BBC.

A global navigation system that can rival GPS is a big part of China's ambition to be a global leader in space, Ms Stickings says.

"The main advantage of having your own system is security of access, in the sense that you are not relying on another country to provide it. The US could deny users access over certain areas, for example in times of conflict."

It could also serve as a back-up if GPS were to go down entirely.

Currently, there are three other satellite navigation systems - Russia's Glonass, Europe's Galileo, and GPS - which is the most-widely used.

The UK is also considering building its own satellite navigation system as it may not be able to access Galileo post-Brexit.

So could Beidou really become the world's most popular system?

"We are likely to see an increased bifurcation of the world into two camps - 'pro-China' and 'pro-US'," says Blaine Curcio, founder of Orbital Gateway Consulting, a Hong Kong-based satellite market research firm.

"And from this perspective, those that go 'pro-China' may be more likely to be distrusting of US and EU satellite navigation services."

But Mr Curcio adds that although the public in developing nations may benefit from having another sat-nav option, in general, there is "no real pressing need".

Better than GPS?
Chinese officials claim that the third-generation Beidou will be as accurate and reliable as GPS, if not more so.

Ran Chengqi, director of the China Satellite Navigation Office, says the system will have a positioning accuracy of 2.5m (8.2ft), which will further be improved to centimetre-level accuracy with additional ground stations.

Meanwhile, the cost of Beidou receiver chips that track and process the satellite signals has fallen in recent years, bringing it on a par with GPS tech.

But despite its technological sophistication, Beidou has a supposed flaw - a two-way transmission process that involves satellites sending signals to earth and devices transmitting signals back. This can compromise accuracy and takes up more spectrum bandwidth.

In contrast, GPS devices do not have to transmit signals back to the satellites.

"Developing and operating a global satellite navigation system is very difficult," explains Brian Weeden, director at the Secure World Foundation.

China has potential to colonise world.

China had the ability to colonize in the history, but didnt do it.

Hehehe… always lovely to read what BBC says on China and Chinese people. I always read them with amusement on what they can come out at any topic on China and Chinese, in particular to read between the lines.

But I definitely won't read at BBC on Russia and Vladimir Putin in late years, back to the period as far as at least the coup in Kiev, and more intensely after Crimea opted to rejoin Russia, but even after the short Georgia saga that coincided with the 2008 Beijing Summer Olympics, the BBC's depictions of Russia and Putin were hardly readable.

For me, practically gone already the times of BBC as a worthy or credible news source of anything even with mild political or strategic values as subtle as this technological development of a GNSS. YMMV
 
.
10 m or 32’ 9¾” is not so great but good as a start.

That's very true, but this is only the initial civilian grade phase. My understanding is that China will send 11 more satelites to complete the consternation, some as backups and some to improve precision. The entire navigation system won't be ready until 2020. Military grade navigation will be much more accurate and will be made available only to China and its closeset friends like Pakistan. Much the same as how the GPS works.

I mean it is good enough for specifying general location/position but not for driving cars since 10 m is larger than the width of most of the roads. Great that China will improve its accuracy by adding more satellites

Five-meter accuracy for the ASIA-PACIFIC region, ten-meter for the rest of the world, at present! For the Civilian, non-commercial access. Should be improved coming to 2020 as more satellites are being launched in 2019 and 2020. Before the end of 2020 the global coverage should be improved as the entire planned satellite constellation is intact, possibly with total of 35 satellites in operations in several orbits. And an even bigger plan for the BDS is in place at 2035, the even better, smarter, more ubiquitously integrated PNT (Positioning and Navigation Time service), centered at the BDS.

yeah this part is really interesting
After the system is completed, Kuilong users will have access to their exact position accurate to about 10 centimeters in less than one minute, no matter where they are, He told China Daily on Thursday on the sidelines of the Sixth China Space Forum in Beijing.

He said the typical accuracy of a GPS reading on a mobile phone or car-mounted GPS receiver is about 5 to 10 meters, and positioning services are scarce to nonexistent in isolated places.
