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.[1] Its sensor is designed by the ITT Corporation.
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.[2] The launch was postponed to September 4, 2008, due to unavailability of the Big Crow telemetry-relay aircraft.[3][4] 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 (1850:57 UTC). The GeoEye-1 satellite separated successfully from its Delta II launch vehicle at 12:49 p.m. PDT (1949 UTC), 58 minutes and 56 seconds after launch.[5]
2009 Anomaly
In December 2009 GeoEye announced it had suspended imagery collections by GeoEye-1, citing an irregularity in the downlink antenna. "The irregularity appears to limit the range of movement of GeoEye-1's downlink antenna, which may in turn affect GeoEye-1's ability to image and downlink simultaneously," GeoEye said.[6]
