China used the Long March III B carrier rocket at the Xichang Satellite Launch Center (and the expedition 1 upper level) to successfully launch the 26th and 27th Beidou navigation satellites in the “one arrow double star” method. These two satellites belong to the medium-Earth orbiting satellite and are the third and fourth group satellites of China Beidou No. 3 Project.
After satellites are in orbit, they can be externally provided after testing and network authentication. According to the plan, the Beidou satellite navigation system will serve the countries along the “Belt and Road” at the end of 2018. The launch was the first launch of the Beidou satellite navigation system in 2018, and it officially opened the new year Beidou high density launch curtain.
The Beidou navigation satellites and supporting launch vehicles (and expedition 1 above) launched by the company were respectively developed by the Institute of Microsatellite Innovation of the Chinese Academy of Sciences and the China Academy of Launch Vehicle Technology. This is the 262nd flight of the Long March series of carrier rockets.
