China's global navigation satellite system, Compass, will provide regional service in 2011 with a constellation of 12 satellites, a navigation industry insider said Thursday.
China aims to make Compass a navigation satellite system of 35 satellites by 2020, which can offer global service.
Compass, or Beidou (Big Dipper) in Chinese, is expected to rival the US-developed GPS, the EU's GPS and Russia's Global Navigation Satellite System, earlier reports said.
