BEIJING, Xichang, Sept. 19 Xinhua Beijing 9 19 am 3 pm 10 points, China with the Xichang Satellite Launch Center in the "Long March III B" carrier rocket, arrow binary "way, the success of the first 14 and15 Beidou navigation satellite was launched into a predetermined transfer orbit.
This is the 2nd arrow binary "way to launch the Beidou navigation satellite Beidou satellite navigation system networking 2012 3rd launch. Experts said the Beidou navigation satellite was successfully launched, marking the Chinese Beidou satellite navigation system fast networking technology has matured.
Beidou satellite navigation system since December 2011, according to the China Satellite Navigation System Management Office announced the commissioning service since the system is stable, improve service performance. System testing and evaluation show that the positioning accuracy of the Beidou system plane 10 meters, 15 meters of elevation, velocity accuracy of 0.2 m / s, the timing accuracy of 50 nanoseconds, and has gradually expanded to transportation, meteorology, fisheries, forestry, telecommunications, water conservancy, mapping applications field, resulting in a significant economic and social benefits.
The "three-step" development strategy in accordance with the Beidou satellite navigation system before the end of 2012, China will launch a Beidou navigation satellite to complete the task of regional network construction, and to enhance the regional system services. Around 2020, will be completed by the Beidou satellite navigation system consisting of more than 30 satellites to provide global coverage of high-precision, highly reliable positioning, navigation and timing services.
Two Beidou navigation satellite launches its carrier rocket Long March III B, owned by the China Aerospace Science and Technology Corporation developed by the China Academy of Space Technology and China Academy of Launch Vehicle Technology. This is the 167th of China's Long March series of carrier rockets perform space launch mission.
