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.
