Geoeye

On September 6, 2008, a commercial satellite GeoEye-1 was launched from Vandenberg Air Force Base, California, with an estimated lifetime of at least 7 years. The satellite is owned by the private company GeoEye Inc. (USA), formed in January 2006 as a result of the merger of Space Imaging and Orbimage – operators of satellites IKONOS and OrbView, respectively.

Briefly about the main thing

GeoEye-1 spacecraft has ultra-high spatial resolution in panchromatic mode, high accuracy of shooting accuracy, as well as very high shooting performance. The satellite allows you to receive a large amount of data in one flight. The shooting accuracy in the plan is 3.5 m (CE90), while the stereo shooting reaches an accuracy of 2.8 m (LE90) in height without the use of reference points.
