WASHINGTON Xichang September 19 Xinhua Beijing at 3:10 on September 19, China at the Xichang Satellite Launch Center in the "Long March III B" carrier rocket, the "stone binary" mode, the success of the first 14 and section 15 Beidou navigation satellite was launched and sent to a predetermined transfer orbit.
This is China's second use of "stone binary" mode Beidou navigation satellite launch is 2012 Beidou satellite navigation system networking 3rd launch. Experts said the Beidou navigation satellite was successfully launched, marking the Chinese Beidou satellite navigation system networking technology has matured rapidly.
According to the China Satellite Navigation System Management Office introduced, the Beidou satellite navigation system from December 2011 to provide commissioning services officially announced since the system is stable, and improve service performance. System testing and evaluation show that the positioning accuracy of the Beidou system plane 10 m, height of 15 meters, velocity accuracy 0.2 m / sec, timing accuracy of 50 nanoseconds, has been gradually extended to transportation, meteorology, fisheries, forestry, telecommunications, water conservancy, mapping and other applications field, resulting in a significant economic and social benefits.
Beidou satellite navigation system according to "three-step" development strategy, before the end of 2012 China will launch a Beidou navigation satellite to complete the task of building regional networking and enhance regional system services. 2020, will be built by the more than 30 satellites of the Beidou satellite navigation system that provides global coverage of high-precision, highly reliable positioning, navigation and timing services.
The launch of two Beidou navigation satellites and launch vehicles, "Long March III B", respectively, by the China Aerospace Science and Technology Corporation China Academy of Space Technology and China Academy of Launch Vehicle Technology Development. This is China's "Long March" rockets 167th execution space launch missions.
