Summary
China launched the Tianlian-3 01 satellite from Wenchang Space Launch Site aboard a Long March 7A rocket on July 29 at 19:50, placing it in its target orbit; the satellite is designed to provide data relay and TT&C (telemetry, tracking, and command) services for crewed spacecraft—including cargo ships, space laboratories, and space stations—as well as for medium- and low-orbit resource satellites. The launch extends China's Tianlian relay satellite constellation, which underpins continuous communications coverage for the Chinese Space Station and reduces the dependence on ground-based tracking networks that constrained earlier crewed missions.
Tianlian-3 01 is the first satellite in a new generation of Chinese data relay satellites, expanding TT&C and data relay capacity for crewed spaceflight and LEO assets in ways that also enhance PLA space-based command and control infrastructure.
Translation
Xinhua News Agency, Wenchang, Hainan, July 29 (Li Guoli, Cui Wanying) — At 19:50 on July 29, China used a Long March 7A carrier rocket at the Wenchang Space Launch Site to successfully launch the Tianlian-3 01 satellite into orbit. The satellite smoothly entered its predetermined orbit, and the launch mission was a complete success. The Tianlian-3 01 satellite is primarily used to provide data relay and telemetry, tracking, and command (TT&C) services for crewed spacecraft such as cargo ships, space laboratories, and space stations, and to provide data relay and TT&C services for medium- and low-orbit resource satellites.
