NANJING: China’s BeiDou-3 system, a global geolocation network, isexpected to be completed in 2020, with a total of 35 satellites,researchers at a conference on the BeiDou Navigation Satellite System (BDS)said.
China has deployed three systems, BDS-1, BDS-2 and BDS-3, to provideaccurate positioning and navigation services to the world, said JinShuanggen, a researcher at Shanghai Astronomical Observatory, ChineseAcademy of Sciences, at the second China (Nanjing) BeiDou SatelliteNavigation Application Expo and Beidou Summit Forum.
“Traditional satellites navigation service is hardly available in theinterior of buildings, underground, underwater and other locations. The BDSsystem provides better accuracy in these locations,” Jin said.
The BDS system, independently constructed and operated by China, currentlyhas 38 in-orbit satellites including 18 BDS-2 and 20 BDS-3.
As a space infrastructure of national significance, the BDS providesall-time, all-weather and high-accuracy positioning, navigation and timingservices to global users, according to a white paper on the system.
