Homegrown PNT System
A high-precision national comprehensive positioning, navigation and timing (PNT) system based on the BeiDou Navigation Satellite System will be finished by 2035, official sources said.
With the completion of the system, China will improve its capability in space and time information services, said Ran Chengqi, head of the Office for the Management of the BeiDou Navigation Satellite System. He made his remarks during the Ninth China Satellite Navigation Conference held in Harbin, capital of northeast China’s Heilongjiang Province, on May 23-25.
Named after the Chinese term for the Big Dipper constellation, the BeiDou project was formally initiated in 1994. It began to serve China in 2000 and the Asia-Pacific region at the end of 2012.
By around 2020, when the BeiDou system is due to go global, it will have more than 30 satellites.
The BeiDou system has been widely used in China for public security, transportation, fishing, power supplies, forestry and disaster relief.
For example, 33,500 taxis and 21,000 buses in Beijing, and 40,000 fishing boats off the country’s coast
