📋 Tender Overview
China successfully launched the 57th and 58th Beidou navigation satellites with the Long March-3B carrier rocket and the upper stage of Yuanzheng-1 at the Xichang Satellite Launch Center. This group of satellites is a medium-circle earth orbit satellite, and is the first group of MEO satellites launched after the completion and opening of China's Beidou-3 global satellite navigation system.
Compared with the previous MEO networking satellites, the functional performance of this group of satellites has been further upgraded in terms of global short message communication capacity, spaceborne atomic clock technology, payload intelligence, etc., and the reliability and service performance of the Beidou system will be further improved after the network is connected, which is of great significance to support the stable operation and large-scale application of the system, and lay the foundation for the design of the next generation of Beidou satellites.
The Beidou navigation satellite and the supporting carrier rocket launched this time were respectively developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology, which are affiliated to the China Aerospace Science and Technology Corporation. This is the 504th flight of the Long March family of launch vehicles.
