GeoEye-1 is a high-resolution Earth observation satellite owned by DigitalGlobe, launched in September 2008. The satellite was acquired in the 2013 purchase of GeoEye.
On 1 December 2004, General Dynamics C4 Systems announced it had been awarded a contract worth approximately US$209 million to build the OrbView-5 satellite. Its sensor is designed by the ITT Exelis.
The satellite, now known as GeoEye-1, was originally scheduled for launch in April 2008 but lost its 30-day launch slot to a U.S. government mission which had itself been delayed. It was rescheduled for launch 22 August 2008 from Vandenberg Air Force Base aboard a Delta II launch vehicle. The launch was postponed to 4 September 2008, due to unavailability of the Big Crow telemetry-relay aircraft. It was delayed again to 6 September because Hurricane Hanna interfered with its launch crews.
The launch took place successfully on 6 September 2008 at 18:50:57 UTC. The GeoEye-1 satellite separated successfully from its Delta II launch vehicle at 19:49 UTC, 58 minutes and 56 seconds after launch.
GeoEye-1 provides 0.41 m (16 in) panchromatic and 1.65 m (5.4 ft) multispectral imagery in 15.2 km (9.4 mi) swaths. The spacecraft is intended for a sun-synchronous orbit at an altitude of 681 km (423 mi) and an inclination of 98 degrees, with a 10:30 a.m. equator crossing time. GeoEye-1 can image up to 60 degrees off nadir. It is operated out of Dulles, Virginia.
At the time of its launch, GeoEye-1 was the world's highest resolution commercial Earth-imaging satellite.GeoEye-1 was manufactured in Gilbert, Arizona, by General Dynamics and the first image was returned on 7 October of Kutztown University in Pennsylvania.
