GeoEye-1 was launched on 6 September 2008 and has the highest resolution of any commercial imaging system. It collects images with a ground resolution of 0.41-meters in the panchromatic or colour pansharpened mode. It acquires multispectral imagery at 1.65-meter resolution, a factor of two better than existing commercial satellites with four-band multispectral imaging capabilities. While the satellite collects imagery at 0.41-meters, GeoEye's operating license from the U.S. Government requires re-sampling the imagery to 0.5-meter for all customers not explicitly granted a waiver by the U.S. Government.
Besides unsurpassed spatial resolution of 0.41-meters or about 16 inches, GeoEye-1 offers three-meter geolocation accuracy, which means that customers can map natural and man-made features to within three meters (about 9 feet) of their actual location on the surface of the Earth without ground control points.
GeoEye-1, a polar-orbiting satellite, can revisit any point on Earth once every three days or sooner. Though it stands two stories high and weighs more than two tons, GeoEye-1 is designed to deftly train the ITT camera on multiple targets during a single orbital pass and is able to rotate or swivel forward, backward or side-to-side with robotic precision. This unrivaled agility enables it to collect much more imagery during a single pass. The satellite makes 15 orbits per day flying at an altitude of 681 kilometers or 423 miles with an orbital velocity of about 7.5 km/sec or 16,800 mi/hr. Its sun-synchronous orbit allows it to pass over a given area at about 10:30 a.m. local time every day. Given its altitude and sun-synchronous orbit, field of view and superior resolution GeoEye-1 can “revisit” any point on the globe every three days or sooner, depending upon the required look angle. The satellite complements GeoEye's current IKONOS system and will collect imagery about 40 percent faster for panchromatic and 25 percent faster for multispectral collections. Together, the IKONOS and GeoEye-1 satellites collect almost one million sq km of imagery per day.
