The Chinese Beidou-2 L2 satellite was launched aboard a Long March 3A rocket from the XiChang Satellite Launch Center near Liangshan in Sichuan province.
The BeiDou-2 or Compass Navigation Satellite System is China's second-generation satellite navigation constellation which will consist of 35 satellites. The constellation is capable of providing continuous, real-time passive 3D geo-spatial positioning and speed measurement and is intended for both civilian and military use. This is the 7th satellite in the constellation to be launched.
The BeiDou-2 navigating system is similar to the American Global Positioning System (GPS), the Russian GLONASS, and the European Galileo systems. Here is a comparison of systems without the Chinese Compass.
