The Belarussian satellite BELINTERSAT-1 (also known as ChinaSat-15) is a communications satellite that will provide TV, Radio broadcasting and internet access to European and Eastern regions. The satellite was built in close partnership with China and contains 20 C-Band and 18 Ku-band transponders. Stationed at 51.5 degrees east in a geostationary orbit the satellite is expected to remain operational for at least 15 years.
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.
The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program.
