The TL 1 (Tian Lian 1) satellite is a geostationary relay satellite based on the DFH-3 Bus (three-axis-stabilized telecommunications satellite platform).
TL 1 are used to support real-time communications between orbiting satellites and ground control stations. This system replaced the earlier network of ground-based space tracking and telemetry stations and space tracking ships.
TL 1 represents the first generation of this new network. Later satellites will be of more advanced larger design.
Tian Lian-1A, launched on 25 April 2008, is positioned at 77° East. The second satellite, Tian Lian-1B was launched on 11 July 2011 and is positioned at 176.77° East. On 25 July 2012 Tian Lian-1C China completed global coverage for its tracking and data relay system. Tian Lian-1D was launched in November 2016. The last satellite, Tian Lian-1E, was launched in July 2021.
