China to Launch first High-throughput Communications Satellite in April

ЦитатаBEIJING, Feb. 17 (Xinhua) -- China plans to launch Shijian-13, its first high-throughput communications satellite, in April, the China Academy of Space Technology (CAST) said Friday.

The 4.6-tonne satellite, with a message capacity of more than 20 GB, will be carried into orbit by a Long March-3B carrier rocket, according to the CAST.

An increase in satellite throughput will provide better access to the Internet on planes and high-speed trains, said Wang Min, deputy head of the CAST's Institute of Telecommunication Satellite.

For the first time, a large number of domestic components have been used on a communications satellite with an orbital life of 15 years, Wang said. It is also the first time electric propulsion has been used on a Chinese satellite.

Shijian-13 has been transported to the Xichang Satellite Launch Center in southwest China's Sichuan Province. After completing in-orbit technical tests, it will be designated as Zhongxing-16.

In 2017, China plans to launch six communications satellites, including Shijian-13 and Shijian-18.

Powerful new satellite to be launched in April

ЦитатаChina will launch its most advanced communications satellite in April as it builds a large capacity network that will enable passengers on jetliners and high-speed trains to use the internet.

Shijian 13, developed by the China Academy of Space Technology, will be lifted on a Long March 3B carrier rocket from Xichang Satellite Launch Center in Sichuan province.

The satellite, which weighs 4.6 metric tons, will stay for 15 years in a geostationary orbit about 36,000 kilometers above Earth, the academy said.

The satellite features a Ka-band broadband communications system capable of transmitting 20 gigabytes of data per second, making it the most powerful communications satellite the nation has developed.

Shijian 13 will use electric propulsion after it enters orbit, which will extensively reduce the chemical fuel the satellite carries. Moreover, it will conduct space-to-ground laser communications experiments, the academy said.
