Mission
Tiantong-1-02
- Type: Communications
- Orbit: Geostationary Transfer Orbit
- Launch Cost: $70,000,000
Designed by the CAST Institute (China Academy of Space Technology), a subsidiary of the Chinese aerospace group CASC and specialized in spacecraft design, the Tiantong-1 02 satellite will be operated by China Satellite Communications Co. Ltd, another CASC subsidiary which owns about ten communication satellites such as the ChinaStar and APStar.
Tiantong-1 02 is the second satellite of China’s first mobile communication network.
It uses a Chinese DFH-4 satellite platform, and, according to its manufacturer CAST, has the highest payload mass utilization rate compared to other satellites of the same family.
The project was launched in 2010 following the 2008 earthquake in Sichuan, where almost all ground communication networks were paralyzed. China had no mobile communication satellites at the time, so it had to lease services from foreign countries, such as Inmarsat in Europe, for its rescue teams.
Location

Rocket
China Aerospace Science and Technology Corporation Long March 3B/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.
Agency
China Aerospace Science and Technology Corporation
The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
