At 33 minutes past 23 o’clock on October 25th (Beijing time), China successfully sent the 16th BD navigation satellite into the reservation transfer orbit with "long March 3 c" carrier rocket in the Xichang satellite launch center.
This is a geostationary orbit satellite, it will operate as a network pattern with the pre-em missioned 15 BD navigation satellites, so that to form regional service capacity. According to the plan, the BD satellite navigation system will provide formal service to most of the Asia-Pacific region at the beginning of next year .
Since Beidou satellite navigation system officially announced to provide pre-commercial service on December 2011, the system has been stable and gradually expanded to some applications fields such as the transportation, meteorology, fishery, forestry, telecommunications, water conservancy, surveying and mapping and so on. It has produced remarkable economic and social benefits. Chinese satellite navigation system management office expressed that the successful launch of the 16th BD navigation satellite has played an important role in promoting the BD satellite navigation system service performance .
BD satellite navigation system is a global satellite navigation system independently developed and operated by China which is compatible with other satellite navigation systems of the world. BD satellite navigation system can not only provide high-precision, high-reliability location, navigation and GPS clock service, but also provide the short message communication service, differential positioning service and manufacturing service. It is an indispensable important spatial information infrastructure for the development of China's national security, economic and social.
At present, China is implementing BD satellite navigation system development plan step by step in line with the "three steps" overall plan, facing the world and forming characteristic BD satellite navigation system development road with prominent area. The first step, establish the BD satellite navigation experimental system in 2000 and make China become the third country in the world who has independent satellite navigation system; the second step, the construction of BD satellite navigation system, be able to cover the most regions of the area of Asian-Pacific at the end of 2012 ; the third step, BD satellite navigation system has the ability of covering the world around 2020.
