BEIJING, Dec. 27 (Xinhua) -- China's BeiDou Navigation Satellite System (BDS) has started to provide global service, said BDS Spokesperson Ran Chengqi on Thursday.
At a press conference of the State Council Information Office, Ran said the construction of the BDS-3 primary system had been completed.
"This signifies that BDS has officially entered the global era as the BDS expands from a regional system to a global navigation system," Ran said.
"From now on, no matter where you go, BDS will always be with you," said Ran.
The positioning accuracy of the system has reached 10 meters globally and five meters in the Asia-Pacific region. Its velocity accuracy is 0.2 meters per second, while its timing accuracy stands at 20 nanoseconds, according to Ran.
By the end of 2018, there were a total of 33 BDS satellites operating in orbit, including 15 BDS-2 satellites and 18 BDS-3 satellites.
China plans to launch another 11 BDS-3 satellites and one BDS-2 satellite in the coming two years to form the complete global network, which will further enhance the global service performance, Ran said.
China began to construct its navigation system, named after the Chinese term for the Big Dipper constellation, in the 1990s and started serving the Asia-Pacific region in 2012.
This year has seen the most intensive launch of the BDS satellites, with a total of 19 satellites being sent into space, setting a new record in the world navigation system construction, Ran said.
As an important achievement during the implementation of reform and opening up over the past 40 years, BDS has been widely used in China's national economy.
More than 14,000 companies and organizations are doing business related to BDS, employing over 500,000 people.
The total number of satellite navigation patent applications in China has reached 54,000, ranking first in the world.
In China, about 6.17 million vehicles, 35,600 postal and express delivery vehicles, as well as 80,000 buses in 36 major cities, use BDS. The system is also used in 3,230 inland river navigation facilities and 2,960 marine navigation facilities.
BDS is used to monitor whether there are any deformations of the Hong Kong-Zhuhai-Macao Bridge to ensure its safe operation, Ran said.
Most of the smartphones sold in the Chinese market support the BDS positioning function. Smart cars based on the BDS high-precision services are expected to enter the market in 2019.
The system has also been widely used around the globe. BDS products have been sold to countries such as Russia, Myanmar, Laos, Cambodia, Thailand, Indonesia, Pakistan, Kuwait, Algeria, and Uganda, according to Ran.
