How to use BeiDou navigation system on your phone


China has just announced the completion and launch of its BeiDou-3 Navigation Satellite System. But, how can we use it?

CGTN recently posted a video showing the differences between China's BeiDou system and other global navigation satellite systems.

And we received some questions, about how to actually use BeiDou for navigation. This video explains how the system works on your phone.

Before we get started, let's clear up a common misconception. A lot of people think if you want to use the BeiDou system, you need to download some sort of "BeiDou apps."

The truth is, you don't need to download any new app for using the system. If you find an app titled "BeiDou" in an app store, it's not official. Regular navigation apps, delivery apps or car-hailing apps are all able to use the positioning service of the BeiDou system.

Civil equipment like our phones, cannot choose which navigation system to use. It will automatically pick the system that has best signal at that time.

So maybe you're using the BeiDou system right now.

But not every smartphone supports BeiDou. Currently, most of the Android phones can use the BeiDou system. But if you are an iPhone user, you are not able to use it because chips carried by the Apple product line do not support the system. To check, you can take a look at the tech specs of your phone.

Another way to find out whether your phone supports BeiDou is through GPS testing apps. Your phone can use BeiDou's services if the app can detect BeiDou's satellites.

There are also people asking whether BeiDou can be used outside China. You can do so just like we can use GPS services in China.

The difference is that BeiDou provides better accuracy in China and the Asia-Pacific region, at five meters, because of its unique layout. The accuracy in other areas is about 10 meters.

How is China's BDS different from other global navigation networks?

https://youtu.be/NXdFg1PRKnQ

China has completed its BeiDou Navigation Satellite System, or BDS, becoming the fourth country in the world with a global navigation network, the other three being GPS of the U.S., GLONASS of Russia and Galileo of Europe.

As the name suggests, the global navigation satellite system provides navigation and location services on a 24-hour basis. From what we know so far, building a sound satellite system costs a bundle. Besides, the other systems are already well-established. So, what makes China's BDS stand out among its competitors?

Firstly, the other systems have 24 satellites in medium earth orbit (MEO). In addition to the 24 satellites, the BDS constellation also has three satellites in geostationary earth orbit (GEO) and three in inclined geosynchronous orbit (IGSO). What's special about the extra six satellites is that they have a relatively fixed range of activity.

This layout can enhance BDS' accuracy in China and the Asia-Pacific region to five meters, in comparison with a 10-meter accuracy in other areas.

Secondly, BDS has a trump card – the short message service. It is a function that allows users to have a two-way communication.

In areas not covered by cellular or communication signals, BDS can make the short message service available in uninhabited areas, such as deserts, forests, and mountainous or polar regions.

With this service, users in distress can inform the rescue team about their location and condition.

As the most populated country in the world, it's important for China to have its own global navigation satellite system to meet the needs of the country's socio-economic development.

In fact, the BDS is also good business. According to the White Paper on the Development of China's Satellite Navigation and Location Services Industry (2020), the country's satellite industry has maintained a 20-percent annual growth since 2012. BDS contributes about 80 percent of it.

The system has also generated tens of billions of dollars, countless high-paying jobs, and stimulated economic growth via big contracts in commercial industries.

And with improvements in functions, it will have much more to offer in the future.

BDS, the Beidou Navigation Satellite System from China

China eyes Silk Road countries for its Beidou satellite system


18 satellites to launch for BDS by 2018


China on Thursday vowed national efforts to complete its Beidou satellite navigation system to serve global users by 2020, with priority going to countries involved in the new Silk Road initiative.

The current goal of developing China's BeiDou Navigation Satellite System (BDS) is to "provide basic services to countries along the land and maritime Silk Roads and in neighboring regions by 2018, and to complete the constellation deployment of 35 satellites by 2020 to provide services to global users," said a white paper released Thursday by the State Council Information Office.

A "globalized" BDS would have "positive and practical significance" in terms of connectivity around the globe, especially the interconnection between China and Southeast Asian countries under the Silk Road plan, known as the Belt and Road initiative, Huang Jun, a professor at the School of Aeronautic Science and Engineering at Beihang University, told the Global Times on Thursday.

In line with the Belt and Road initiative, China will jointly build satellite navigation augmentation systems with relevant nations and promote international applications of navigation technologies, the white paper states.

To fulfill the 2018 goal, the country plans to launch some 18 satellites for the BDS by 2018, Ran Chengqi, BDS spokesperson, told a press conference on Thursday.

"In priority Chinese cities such as Beijing and Urumqi in Northwest China's Xinjiang Uyghur Autonomous Region, as well as low latitude countries like Thailand, the BDS is capable of offering a positioning accuracy of better than five meters," said Ran, who is also director of China's Satellite Navigation System Management Office.

Since 2015, the country has sent up seven more satellites into space in support of the BDS, including five navigation satellites and two backup satellites, Ran added, citing Sunday's launch of the BDS' 23rd satellite - a backup satellite - as an example.

In 2020, the BDS might offer different positioning accuracy choices and could provide centimeter-level accuracy under certain requirements, said Lu Weijun, a BDS expert at Beijing University of Posts and Telecommunications.

Unique features

Despite being a late starter compared with the US-developed GPS, China's BDS has unique features, Huang said, citing the BDS short-message communication service as an example.

"The short-message communication service is mainly useful in places with insufficient ground and mobile communication capabilities, such as deserts, seas and disaster areas where communication facilities have been destroyed," Lu told the Global Times.

More than 40,000 fishing vessels along China's coastline have been equipped with the BDS application terminals, Ran said, adding that they also provided better communication for islands near the coastline.

The BDS short-message communication service is mainly handled by five Geostationary Orbit (GEO) satellites, Lu said. Located above China, the five GEO satellites mainly serve a coverage area of Chinese territories and the Asia-Pacific region" and "could be used to locally enhance the signal in wartime, when other satellites might have been closed."

An independently designed global navigation and positioning network would also contribute to national security, Huang said. Industrial chain

China is developing chips, modules and other basic products based on the BDS and other compatible systems, and fostering an independent BDS industrial chain, the white paper noted.

"By the end of April, the BDS technology has been applied to more than 24 million terminals and over 18 million mobile phones," Ran said.

It is expected that by the end of this year, up to 50 million mobile phones will have been installed with domestic chips that will be compatible with three satellite navigation systems, namely the BDS, GPS and Russia's GLONASS, Wang Hansheng, vice president of Olink Star, a Beijing-based company that makes navigation satellite system products, told the Global Times.
