China will be built in 2020, global coverage of the beidou satellite navigation system

Date:2010/5/20

According to "the people's liberation army newspaper, May 20, 2010 journalists from 19 of the China's first satellite navigation academic annual conference that China will be completed in 2020, global coverage of the beidou satellite navigation system.


Satellite navigation system is a national comprehensive national strength, the core competitiveness and technological innovation ability. Aerospace researchers more than 10 years after our country the majority of the common efforts, in 2000, the beidou satellite navigation experimental system into the transmitting network, system construction, the phase of steadily made in our country after the United States, Russia with independent satellite navigation system.


Chinese academy of engineering qi said, our country according to the principle of opening, independence, compatibility, progressive, independent development of the global satellite navigation system, practice the "three-step" development strategy: the first step is to use a small amount of satellite using geostationary orbit above the earth to complete test task, for the beidou satellite navigation system construction technology experience and training talents, developing some ground application infrastructure equipment, etc.; The second step, was completed in 2012 to cover our country and the area surrounding the beidou satellite navigation system; Third, to built in 2020 by five geostationary orbit and 30 non stationary orbit satellite network formation of the global satellite navigation system, the formation of global coverage.


Since 2000, the operation of beidou satellite navigation experimental system is built, and the successful application of the national economic construction and national security, and many other areas, successfully completed the first step on the "three steps". At present, the beidou satellite navigation system development is in a crucial period of the second step. On 17 January this year, in xichang satellite launch center in China with "ChangSanBing" carrier rocket successfully will be the third beidou navigation satellite into orbit, marked the beidou satellite navigation system engineering construction is an important step.


At the moment, the beidou system with combination of navigation and communication service characteristics, has gradually been recognized by domestic users, in the fishing, transportation, electricity, and is widely used in various fields, such as national security, especially in sichuan wenchuan, yushu in qinghai has played an important role in earthquake relief, produce remarkable economic benefit and social benefit.
