Intelsat 19 is a geostationary communications satellite operated by Intelsat. It was constructed by Space Systems Loral, based on the LS-1300E satellite bus. It was successfully launched by Sea Launch using a Zenit-3SL carrier rocket on 1 June 2012. Upon entering service it replaced Intelsat 8 at 166° East Longitude. ==Telecommunications and Service History== Intelsat 19 carries 24 C-band and 36 Ku band transponders. The C band payload covers the Asia-Pacific region while the Ku band transponders provide Direct to Home television to Australia. It is expected to operate for fifteen years. In June 2012, Intelsat 19 successfully transferred to geostationary orbit. All of the satellite’s communications antennas were in their operational positions, and the communications payload was being tested. Data received from the satellite indicated that the south solar array was damaged, and that the power available to the satellite will be reduced. In-orbit testing was expected to be completed by mid-July. In July 2012, Intelsat 19 completed its in-orbit testing and the satellite drifted to its final location at 166 East, where it was expected to begin service in mid-August. On 13 August 2012, the satellite entered commercial service as customer traffic previously on Intelsat 8 was transitioned over. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Intelsat 19」の詳細全文を読む スポンサード リンク
