The world’s highest resolution
commercial Earth-imaging satellite

GeoEye-1 will be equipped with the most advanced technology ever used in a commercial remote sensing system. The satellite will be able to collect images at 0.41-meter panchromatic (black & white) and 1.65-meter multispectral resolution*. Just as important, GeoEye-1 will be able to precisely locate an object to within 3 meters of its true location on the surface of the Earth. This degree of inherent geolocation accuracy has never been achieved in any commercial imaging system. The satellite will be able to collect up to 700,000 square kilometers of panchromatic (and up to 350,000 square kilometers of pan-sharpened multispectral) imagery per day. This capability is ideal for large scale mapping projects. GeoEye-1 will be able to revisit any point on Earth once every three days or sooner. Customers will have a choice of ordering BASIC, GEO, ORTHO and STEREO imagery as well as imagery-derived products, including DEMs (digital elevation models) and DSMs (digital surface models), large area mosaics and feature maps.

A polar orbiting satellite, GeoEye-1 will make 12 to 13 orbits per day flying at an altitude of 684 kilometers or 425 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. The entire satellite will be able to turn and swivel very quickly in orbit to point the camera at areas of the Earth directly below it, as well as from side to side and front to back. This agility will enable it to collect much more imagery during a single pass. Watch GeoEye-1!!

Dulles, VA-based GeoEye is the prime contractor responsible for developing the entire GeoEye-1 satellite system. GeoEye-1 is designed and manufactured by General Dynamics/C4 Systems (Gilbert, AZ). ITT (Rochester, NY) is providing the electro-optical camera to General Dynamics, including the optical telescope assembly, the detectors and focal plane assembly and the high-speed digital processing electronics. MacDonald, Dettwiler and Associates and Orbit Logic are upgrading elements of GeoEye’s ground segment. Receiving antennae will be located at the Company’s headquarters in Dulles, VA and Barrow, AK. Kongsberg Satellite Services will provide leased ground terminal services in Tromso, Norway and Troll, Antarctica.

*Data reflects ground sample distance resolution at Nadir for exclusive use by the U.S. government and any foreign government that the U.S. government may designate. Imagery sold to commercial customers will be resampled to 0.5-meter resolution. GeoEye’s current operating license with NOAA does not permit the commercial sale of imagery below 0.5-meter resolution.
