China on the 16th in Xichang Satellite Launch Center, “one arrow and two stars” again successfully launched two “Beidou Star”, fully completed the beidou 3 global system core constellation deployment at the same time, created a global satellite navigation system network speed world record. Beidou system is China’s self-built, independent operation of the global satellite navigation system, in 2009 officially launched Beidou 3 global system construction. It is understood that Beidou III consists of three geostationary orbit satellites, three tilted geosynchronous orbit satellites and 24 medium-circle Earth orbit satellites.
24 satellites spread over three orbital surfaces, providing navigation services to users around the world.
“The Mid-Circle Earth Orbit satellite is the main satellite of Beidou III’s global system. According to our design, 24 satellites are evenly distributed on three orbital surfaces at an altitude of about 20,000 km, each with eight. Wang Ping, chief designer of Beidou 3, said, “In this way, we can ensure that we can see five or six satellites at any time in any location in the world, which is the premise that China Beidou can provide global service.” ”
Long Sanjia series rocket escorts 53 Beidou satellites into orbit
At 15:22 on the 16th, “after 80” 01 commander Bai Chunbo issued the password, the milky white Long March rocket holding up the Beidou double stars to fly into space. This is the 108th launch of the Long March III A-series rocket and the 321st flight of the Long March Rocket.
“In the 12 years since the launch of the first Beidou-2 navigational test satellite in 2007, the Changsana series of rockets has been successful lying 38 times, escorting 53 Beidou satellites into their intended orbit. Jiang Jie, a member of the Chinese Academy of Sciences and chief designer of the Long March III A series launch vehicle, said.
After more than three hours of flight, the satellite entered its intended orbit. The Xichang Satellite Launch Center subsequently declared the launch a complete success.
An average of 1.2 satellites launched per month to set a new world record.
In recent years, Beidou system ushered in a high-density launch period. Yang Changfeng, chief designer of China’s Beidou satellite navigation system, told reporters at the launch site that 18 launches have been made since the first launch of Beidou III’s global network satellite in 2017.
Yang Changfeng said that in the project 7 major systems, more than 300 participating units, more than 100,000 scientific research personnel, the joint efforts, just over two years, on the successful implementation of 18 network launches, 28 Beidou 3 network satellite and 2 Beidou 2 backup satellite successfully into the scheduled orbit, ” With an average monthly high density of 1.2 satellites, the global satellite navigation system network speed record was broken.”
“At present, Beidou 3 project construction has entered the decisive sprint stage, we plan to launch two geosynchronous orbit satellites by June 2020, the full completion of Beidou 3 system, to provide better services for the world. Yang Changfeng said that at the same time, has started the overall demonstration of the continuous development of beidou system and key technical work, plans to complete by 2035 Beidou system as the core of the integrated positioning, navigation, timing (PNT) system.
