BeiDou constellation. (Image: BeiDou program) China completed its worldwide BeiDou navigation satellite system with the launch of its final satellite on June 23, according to China Global Television Network. The satellite launched aboard a Long March-3B carrier rocket from the Xichang Satellite Launch Center at 9:43 a.m. Beijing time (0143 GMT) on Tuesday, marking the completion of the country’s domestically developed BeiDou constellation. The launch followed a delay of after originally being scheduled for July 16 because of a technical issue discovered in pre-flight tests. The final satellite is a geostationary earth orbit satellite of the BDS-3 system. It is the 30th BDS-3 satellite and the 55th BeiDou satellite. BDS-3 is a a 30-satellite navigation system. BDS-3 offers high-precision positioning and short message communication. Begun in 1994, BDS-1 was completed in 2000 to provide services to China. In 02012, BDS-2 was finished, and has provided navigation service to the Asia-Pacific region. Once the final satellite achieves orbit and is checked out successfully, BDS-3 will provide navigation services worldwide. Screenshot: China Global Television Network
