China has aspirations for its quickly broadening Beidou satellite navigation system to serve the entire world, not simply Asia, however will it truly be able to match the reputable – and US-owned – GPS system?
Dalintai – a herder in northern China – utilized to travel miles every day on his bike to provide water for his animals.
Now, according to the the Xinhua news agency, all he has to do is send out a text to run an automatic water shipment system.
“I am able to deliver water to my sheep and cattle wherever and whenever I want via this system,” he states.
The message is communicated over China’s broadening Beidou satellite navigation system, which is currently being utilized utilized for transportation, farming as well as accuracy rockets.
Originally created for the Chinese military to minimize dependence on the US-owned GPS, Beidou has actually developed into an industrial chance as its protection has actually broadened.
Last month, regional authorities bought 33,500 – about half of all taxis – in Beijing to set up Beidou, and the Chinese federal government has actually set an objective that brand-new automobiles will be Beidou- assisted by 2020.
Domestic phone brand names such as Huawei, Xiaomi and OnePlus are now Beidou- suitable, although Apple did not include the Chinese system to its brand-new line-up of iPhones revealed on 12September
Chinais progressively eager to promote its technological expertise to the remainder of the world.
YangChangfeng, the system’s chief designer, has actually been singing about his nation’s aspiration to bring in more abroad customers.
“China’s Beidou is the world’s Beidou, and the global satellite navigation market is certainly Beidou’s market,” he informed Global Times in 2015.
Named after the Chinese word for the Big Dipper or Plough constellation [Ursa Major], Beidou has actually remained in the works for over 20 years however just ended up being functional within China in 2000 and the Asia-Pacific area in2012
When total in 2020, it will have a constellation of 35 satellites to offer global protection. This year alone, there have actually been more than 10 Beidou satellite releases –two more were launched this week More are prepared in what state media refer to as a”period with unprecedentedly intensive launches”
By completion of 2018, it will cover nations along the Belt and Road Initiative (BRI) – a huge China- led facilities and trade program, part of exactly what it calls the”Space Silk Road” Beidou currently covers 30 nations included with the BRI, consisting of 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, informs the BBC.
A global navigation system that can match GPS is a huge part of China’s aspiration to be a global leader in space, Ms Stickings states.
“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 might likewise work as a back-up if GPS were to go down completely.
Currently, there are 3 other satellite navigation systems – Russia’s Glonass, Europe’s Galileo, and GPS – which is the most-widely utilized.
The UK is likewise thinking about developing its own satellite navigation system as it might not be able to gain access to Galileo post-Brexit
So could Beidou truly end up being 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’,” states Blaine Curcio, creator of Orbital Gateway Consulting, a Hong Kong- based satellite marketing research company.
“And from this perspective, those that go ‘pro-China’ may be more likely to be distrusting of US and EU satellite navigation services.”
ButMr Curcio includes that although the general public in establishing countries might take advantage of having another sat-nav alternative, in basic, there is”no real pressing need”
Better than GPS?
Chinese authorities declare that the third-generation Beidou will be as precise and trustworthy as GPS, if not more so.
RanChengqi, director of the China Satellite Navigation Office, states the system will have a placing precision of 2.5 m (8.2 feet), which will even more be enhanced to centimetre-level precision with extra ground stations.
Meanwhile, the expense of Beidou receiver chips that track and process the satellite signals has actually fallen in current years, bringing it on a par with GPStech
But regardless of its technological elegance, Beidou has a supposed flaw – a two-way transmission procedure that includes satellites sending out signals to earth and gadgets transferring signals back. This can jeopardize precision and uses up more spectrum bandwidth.
In contrast, GPS gadgets do not have to transfer signals back to the satellites.
“Developing and operating a global satellite navigation system is very difficult,” discusses Brian Weeden, director at the Secure World Foundation.

“It’s one thing to get it working, it’s another to keep it working consistently and create trust among users.”
The most significant strength of GPS has actually been its consistency and dependability over the last couple of years, includes MrWeeden
“It doesn’t just broadcast an accurate signal; it has done so without hardly any interruption for decades.”
Of possibly more issue to Western federal governments is President Xi Jinping’s method to establish a smaller sized, smarter military – and Beidou’s important function in this.
The army is obviously utilizing Beidou for precision-guided rockets, reconnaissance workouts, and as a brief messaging platform – something that GPS does not have.
“There is no doubt of the benefits to the military of enhanced accuracy and an increase from regional to global coverage,”Ms Stickings notes.
“A potential benefit to the military could be in how it could deny or degrade the signal received by other users of the system.”
