In early 2001 satellite operator PanAmSat ordered a new C-band GEO satellite with Orbital Sciences Corp. (Orbital ATK – Northrop Grumman), designated Galaxy-12, to be located at 72° W longitude. In late 2001 PanAmSat exercised an option for two additional C-band spacecraft. The satellites would distribute entertainment and information to cable television systems, TV broadcast affiliates, DTH-television operators, ISP’s, telecommunications companies and corporations.

In the autumn of 2003, PanAmSat, modified its contract with Orbital for Galaxy-15, the third Star-2 spacecraft under construction for its North American fleet. A second U.S. Government sponsored L-band Wide Area Augmentation System (WAAS-GEO 3) payload was added to the satellite’s original C-band commercial payload as part of the Geostationary Communications and Control Segment (GCCS) program being integrated by Lockheed Martin for the U.S. Federal Aviation Administration. Galaxy-15 relays GPS navigation information to in-flight aircraft, providing super-accurate guidance to pilots at thousands of airports and airstrips where there is currently no precision landing capability.

In 2010 Galaxy-15 stopped reacting to ground commands and began drifting along the geostationary arc, with the transponders still broadcasting. After a monthlong journey, the batteries were finally drained in December 2010 leading to a reset of the systems. After that, control was regained over the satellite.

In February 2007, after the acquisition of PanAmSat, satellite operator Intelsat officially named the satellite Galaxy-15.

Galaxy-15 was successfully launched on October 13th, 2005, on an Ariane 44L rocket, operated by launch operator Arianespace, from the Kourou Space Port in French Guyana.
