China's Beidou Navigation Satellite System Becomes Operational
January 3, 2012
China's new satellite navigation system, Beidou, became active on Dec. 27, 2011. China has launched 10 satellites for the Beidou system and plans to put six more in orbit this year to enhance the system’s accuracy and expand its service. According to a BBC report, the system is accurate to 10m, which is low compared to that of the U.S., but it should improve as the number of satellites grows.
