Beidou Navigation Satellite System press conference is held at the Briefing Hall of the State Council Information Office on December 27, 2012.
BeiDou Navigation Satellite System is built and run independently by China. It is compatible with other GNSS, and provides worldwide high-precision, highly reliable positioning, navigation and timing services at all-weather, all-time for all types of users.
Since BeiDou Navigation Satellite System provided test run services on December 27, 2011, it has successfully launched 6 more satellites in 4 launches, expanded the system coverage, enhanced constellation robustness and improved system accuracy. Currently, all in-orbit satellites and ground systems run stable and system performance meets the design requirements through the testing and evaluation of various types of user terminals. From today, BeiDou Navigation Satellite System officially starts o provide continuous passive positioning, navigation and timing services for China and surrounding area, as well as active positioning, two-way timing and short message communication services originally provided by BeiDou Experimental Navigation Satellite System.
