Intelsat 18 is a television satellite of the International Telecommunications Satellite Consortium ( Intelsat ) based in Luxembourg .
He was by the company Orbital Sciences Corporation built and 5 October 2011 on a Zenith 3 - carrier rocket from the Baikonur Cosmodrome transported out into space. Its lifespan is expected to be 17 years. The Zenit rocket initially placed the satellite in low earth orbit and, after separating from the rocket at 3:34 a.m. UTC on October 6, 2011, with the help of multiple ignitions of the Blok-DM-SL upper stage, in geotransfer orbit. From there, the satellite will reach its final geostationary position at 180 ° east longitude with its own drive over the next few days.
Intelsat 18 replaces the Intelsat 701 satellite, launched in 1993, and is to be used from its position in North America, French Polynesia, the Cook Islands, Australia, New Zealand, New Caledonia, Vanuatu, Fiji, Tonga, Samoa and other islands in the Pacific and East Asia with image and Supply data services. Two fold-out antennas with a diameter of 2.5 × 2.7 meters each and an antenna with a diameter of 1.4 meters mounted on the satellite, as well as 24 C-band and 12 Ku-band transponders with traveling wave tube amplifiers are available for this purpose. These are installed in two groups of 16 or 8 transponders each, so that 8 or 4 are available as a reserve. The energy supply is provided by four panels with UTJ - gallium arsenide solar cells.
