GeoEye-1
GeoEye-1 is a high-resolution earth observation satellite owned by GeoEye, which was launched in September 2008.
==History==
On December 1, 2004, General Dynamics C4 Systems announced it had been awarded a contract worth approximately $209 million to build the OrbView-5 satellite.〔(【引用サイトリンク】title=General Dynamics to Build Satellite to Improve U.S. Government Access to High-Resolution Earth Imagery )〕 Its sensor is designed by the ITT Exelis.
The satellite, now known as GeoEye-1, was originally scheduled for April 2008 but lost its 30-day launch slot to a U.S. government mission which had been delayed. It was rescheduled for launch August 22, 2008 from Vandenberg Air Force Base aboard a Delta II launch vehicle.〔(【引用サイトリンク】title=GeoEye-1 Launch Details )〕 The launch was postponed to September 4, 2008, due to unavailability of the Big Crow telemetry-relay aircraft.〔(Restatement Pulls GeoEye's Goals Back Down to Earth )〕〔(【引用サイトリンク】title=Delta 2 rocket launch of GeoEye craft postponed )〕 It was delayed again to September 6 because Hurricane Hanna interfered with its launch crews.
The launch took place successfully on September 6, 2008 at 11:50:57 a.m. PDT (18:50:57 UTC). The GeoEye-1 satellite separated successfully from its Delta II launch vehicle at 12:49 p.m. PDT (19:49 UTC), 58 minutes and 56 seconds after launch.〔(【引用サイトリンク】title=Delta 2-335 Mission Status Center )〕
