The GeoEye-1 satellite is equipped with the most advanced technology ever used in a commercial remote sensing system. The system provides images at nadir with 0.5-meter panchromatic (black & white) and 2-meter multispectral resolution. Just as important, 3 meters of inherent geolocation accuracy has never before been achieved in any commercial imaging system.

A polar orbiting satellite, GeoEye-1 orbits the Earth 15 times per day flying at an altitude of 681 kilometers with an orbital velocity of about 7.5 km/sec. Its sun-synchronous orbit allows it to pass over a given area at about 10:30 a.m. local time every day. Industry-leading agility means the entire satellite turns and swivels very quickly in its orbit to aim the sensor at areas directly below, as well as from side-to-side and front-to-back, enabling it to collect more imagery during a single pass

GeoEye-1 will be able to revisit any point on Earth once every three days or sooner. The satellite collects up to 700,000 square kilometers of panchromatic (and up to 350,000 square kilometers of pan--sharpened multispectral) imagery per day.
