According to science and technology daily, Xi'an Satellite Measurement and control center announced that the 54th Beidou navigation satellite has recently completed various on orbit tests and network access assessment, and has officially entered the network to provide services. This is the penultimate satellite of Beidou satellite navigation system, with only the last step left before it is fully completed.
At 1955 hours on 9 March, at the Xichang Satellite Launch Centre, China successfully launched the Beidou-3 GEO-2 satellite by using the Long March III B carrier rocket.
Geosynchronous orbit (GEO) satellites are affectionately known as
The geo-2 launched last time was the 54th satellite of Beidou system, the 29th satellite of Beidou 3, and the penultimate satellite of Beidou system. Finally, 30 Beidou 3 satellites were launched and networked, and the construction of Beidou global navigation system was completed half a year in advance!
It will work together with beidou-3 geo-1 satellite launched on November 1, 2018 to verify the active positioning function of the new system of Beidou system and start the comprehensive upgrade of radio measurement function.
At present, Beidou satellite navigation and positioning system still has the last satellite, that is, satellite 55, which is also a geo geosynchronous orbit satellite. According to Yang Changfeng, chief designer of Beidou satellite navigation system engineering, the last networking satellite has arrived at Xichang Satellite Launch Center, and all preparations are progressing orderly. It is planned to launch in June.
Yang Changfeng said that China's Beidou navigation system took more than 20 years to complete the development of other global satellite navigation systems for more than 40 years, Beidou global system construction achieved two years 17 arrows 29 star high-density launch network Lianzheng, created the miracle of world satellite navigation, known as the world satellite navigation
