China's location detection tech seeks to hit big time in Belt & Road regions
A recurring theme in the annual Government Work Report, the latest edition of which Premier Li Keqiang presented to the National People's Congress on March 5,has been promotion of high-end manufacturing and the Belt and Road Initiative, and helping Chinese companies to globalize their equipment and homegrown technologies. The BeiDou Navigation Satellite System is a perfect example of that spirit.
The GPS-like navigation system, a product of the Chinese National Space Administration, and managed by the China Satellite Navigation Office, is to accelerate its expansion into economies along the Belt and Road Initiative as China plans to launch six to eight BeiDou satellites this year. BeiDou has made significant progress in terms of accuracy of location detection.
The go-global strategy is part of China's broad plan to build a BeiDou navigation system with a constellation of 35 satellites by 2020. In comparison, GPS consists of 24 satellites.
“The globalization era for BeiDou is coming,” said Miao Qianjun, secretary-general of the Global Navigation Satellite System and Location-based Services Association of China. The GLAC was founded in 1995 to promote the commercial application of BeiDou technologies.
“China is supporting BeiDou's exports roughly the same way it supports exports of high-speed railway products and technologies. BeiDou will become another high-tech name card for China,” Miao said.
In February, the GLAC invited its enterprise members involved in BeiDou-related industries for discussions. With help from the National Development and Reform Commission, China's top economic planner, it set up an alliance for enterprises that seek to take BeiDou products and solutions to markets along the Belt and Road Initiative.
“We've received affirmative responses from 27 enterprises within a week. They are all eager to be part of our efforts,” Miao said, adding the alliance members will receive financial support from the government.
Policy support for navigation technologies was first articulated in a guidance released by the NDRC in November 2016. It called for more help for enterprises to enable them to apply BeiDou technologies in Thailand, Laos, Indonesia and other ASEAN countries.
“The close economic ties between China and ASEAN will pave the way for BeiDou's entry. More importantly, in Southeast Asian countries located in low latitudes, BeiDou is more accurate than GPS,” said Ming Dexiang, director of the Beidou Open Laboratory, an agency that promotes commercial applications of BeiDou.
Steady improvements to BeiDou's technologies have helped improve the accuracy of its navigation and location-detection systems. China announced earlier this year that BeiDou's satellites can locate ground-based users to an accuracy level of one or two meters of their exact location with the help of a new chip. Prior to this, BeiDou's accuracy level was a radius of 10 meters from the actual spot.
Li Xueli, an engineer working with BeiDou, said: “For users, there are two big improvements. One is the time the system takes to process your journey. This is down from 30 seconds to just three seconds. The second improvement is the position accuracy. The system can now tell if the car is on the main road or side road.”
With precision of 1 to 2 meters, BeiDou is just behind the European Union's Galileo satellite system that gives consumers an accuracy level of just 1 meter. GPS' accuracy level is 5 meters while Russia's GLONASS satellite gives an accuracy level of 4.5 meters to 7.4 meters.
Given the potential for wresting lead globally, China is accelerating steps like launching new navigation satellites to expand the coverage area of BeiDou.
Yang Yuanxi, an academician with the Chinese Academy of Sciences and a member of the CPPCC National Committee, said: “China will launch six to eight satellites this year. After constructing a network of 18 satellites by around 2018, we will serve economies along the Belt and Road Initiative.”
