On 22 August, GeoEye will launch GeoEye-1 from the Vandenburg Air Force Base in California. The satellite, capable of imaging up to about 700,000 square kilometers a day, will be able to distinguish objects that measure 0.17 square meters, providing images at its highest resolution for classified military and intelligence uses. US regulations forbid satellite companies from selling images with resolutions better than 0.25 square meters. GeoEye claims that GeoEye-1 will still offer the highest-resolution colour images available on the market, able to spot a person on the ground. Competitor DigitalGlobe’s QuickBird satellite currently offers resolution that can distinguish objects that measure 0.36 square meters with ground truth of 27 metres, while GeoEye-1 will offer 3 m ground truth capability. The improved accuracy is due to the high quality of its star trackers, which were initially developed by Ball Aerospace for military applications. GeoEye-1 has a predicted life span of seven years.
