Telstar 7

Wiki

Galaxy 27 (formerly Telstar 7) is a communications satellite owned by Intelsat. It was at first located at 129° W longitude, serving most of the North American market. It was built by Space Systems/Loral, as part of its FS-1300 line. This satellite experienced a power failure of several days in 2004 and returned to service with reduced capacity. In May 2011, Galaxy 27 was redeployed to 45.1° E longitude in order to expand Intelsat's services in the Middle East and West Asia. In October 2013, Intelsat moved the satellite to an inclined orbit at 66° E. At its inclined orbit of 2.4° at 66° E, Galaxy 27 is in a collocated orbit with Intelsat 17.
