2011 年 12 2, containing the Beidou navigation satellite Long March III A carrier rocket at the Xichang Satellite Launch Center in China blasted off. 5:07 the same day, China’s Xichang Satellite Launch Center Long March III A carrier rocket successfully tenth Beidou navigation satellite into space transfer orbit.

China Network, December 27 (Reporter Liu Jinyang) 10 am, the State Council Information Office organized the first Beidou satellite navigation system, a press conference. Beidou satellite navigation system spokesman, China’s satellite navigation system management office Ran Chengqi Xuan cloth, starting today, China and the surrounding areas to provide continuous navigation and timing services. End of next year, the Beidou system will provide the basic completion of the formal run services, then the positioning accuracy of the coverage area 10 meters.

Beidou satellite navigation system is China’s own development, independently and with satellite navigation system compatible with rest of the world share of global satellite navigation system, worldwide all-weather, all-time for all types of users with high-precision, highly reliable positioning, navigation and timing services, and both short-message communication capabilities. Current Beidou satellite navigation system has launched 10 satellites, and built a basic system. Beidou satellite navigation system in the test system to retain the active position and a short message communication services.

Ran bearing its said, according to “quality, security, application, and efficiency” of the general requirements, adhere to the “independent, open, compatible, progressive” development principles, the Beidou satellite navigation system according to “three-step” development strategy steadily. The first step, built in 2000 Beidou satellite navigation experimental system, making China the world’s first satellite navigation system with independent three countries. The second step, the construction of the Beidou satellite navigation system, around 2012, most of the Asia Pacific region covering the service capacity. The third step, about 2020, forming the Beidou satellite navigation system, global coverage.

2012, the network launch plans in accordance with the Beidou system, but also launched six satellite network to further expand the system service area and improve service performance, covering most parts of the Asia-Pacific service capabilities.
