On October 20th, it was announced that all Beidou-3 satellite launches will be completed by the end of June next year, half a year ahead of schedule. Beidou will contribute a globally covered, advanced, and first-class satellite navigation system to the world.
Today, it was learned from the China Satellite Navigation System Management Office that the first China Central Asia Beidou Cooperation Forum was recently held in Nanning, Guangxi. Ran Chengqi, director of the China Satellite Navigation System Management Office, stated in an interview with reporters that all Beidou-3 satellite launches will be completed by the end of June next year, half a year ahead of schedule. Beidou will contribute a globally covered, advanced, and first-class satellite navigation system to the world.
Ran Chengqi said in an interview with a reporter from Beidou Network that the original plan was to build the Beidou-3 system by the end of 2020. Now he is very confident that all Beidou-3 satellite launches will be completed by the end of June next year, which is half a year ahead of schedule. The construction task of Beidou-3 is about to be completed, and its stable operation will be elevated to the same important level as engineering construction, application promotion, and international cooperation. The stable operation of the Beidou system is also at the forefront of the world, contributing to a global coverage, advanced performance, and first-class satellite navigation system for the world.
According to public information, the construction of the Beidou-3 project officially began in 2009. The space segment of the Beidou-3 satellite navigation system consists of 27 medium Earth orbit satellites, 5 synchronous orbit satellites, and 3 inclined synchronous orbit satellites, providing two service modes: open service and authorized service. Open services provide free positioning, speed measurement, and timing services in the service area, with a positioning accuracy of 10 meters, timing accuracy of 50 nanoseconds, and speed measurement accuracy of 0.2 meters per second. Authorization services provide more secure positioning, speed measurement, timing, communication services, and system integrity information to authorized users.
At 2:07 am on November 19, 2018, China successfully launched the 42nd and 43rd Beidou navigation satellites using the Long March 3B carrier rocket from the Xichang Satellite Launch Center in a "one rocket, two satellites" manner. At this point, the deployment of the space constellation of China's Beidou-3 global networking basic system has been successfully completed, marking a "crucial step" for China's Beidou to move from regional to global.
On December 27, 2018, the basic system of Beidou-3 was completed and began providing global services.
It is reported that the main outcome of the China Central Asia Beidou Cooperation Forum, the Nanning Declaration, specifically proposes to deepen exchanges and cooperation in the field of satellite navigation systems between China and Central Asian countries, promote technology exchange, joint research and development, and application industrialization of satellite navigation systems among countries, and share the development achievements of China's satellite navigation system.
