(ECNS) — China officially completed its second-generation geosynchronous orbit data relay satellite system as a Long March-3B carrier rocket carrying the Tianlian II-03 satellite lifted off from the Satellite Launch Center on Wednesday. from Xichang in southwest China’s Sichuan Province.
The Tianlian II-03 satellite was produced by the Chinese Academy of Space Technology and is the third satellite of China’s second-generation geosynchronous orbit data relay system.
It will provide data relay and TT&C (telemetry, tracking and command) services for manned spacecraft and resource satellites in low and medium orbit. It will also support TT&C for launching spacecraft.
After its orbit and the end of the tests, the satellite, as well as the TianlianII-01 and TianlianII-02 satellites, will provide 24-hour uninterrupted communication for the satellites in low and medium orbit.
The first science lesson broadcast live from the country’s space station also passed through Tianlian’s communication systems. In addition, it supports space call communication, module docking, spacewalks and other important tasks.
The successful development of the TianlianII-03 satellite proves that Tianlian II satellites can be deployed quickly, which will support multi-satellite rapid networking in orbit.
China has successfully developed two generations of data relay satellite systems in geosynchronous orbit. The first generation includes five Tianlian I satellites, while the second generation includes three Tianlian II satellites.
This was the 426th flight mission of the Long March series of carrier rockets.
