Tianlian 2-05

Overview

Destination: Geostationary Transfer Orbit
Mission: Communications

Geostationary Transfer Orbit Launch Complex 2 (LC-2) Xichang Satellite Launch Center, People's Republic of China

Tianlian is a Chinese data tracking and relay communications geostationary satellite series. The TL 2 (Tian Lian 2) satellites represent the second generation of this relay satellite network, and is based on the DFH-4 Bus, a three-axis-stabilized telecommunications satellite platform. TL 2 will be used to support real-time communications between orbiting satellites and ground control stations. This system will replace the current network of ground-based space tracking and telemetry stations and space tracking ships.

Long March 3

Family:
Configuration: B/E

The Long March 3B / E (G2) (CZ-3B / E) is one of the most successful medium-range launchers and the strongest variant of the CZ-3 series. It was specially developed for the transport of heavy communications satellites into a geostationary transfer orbit. The additional designation "E" stands for a higher payload fairing, stretched boosters and extended fuel tanks at the first stage, over the CZ-3B.
