GeoEye-1 Satellite Sensor (0.46m)
The GeoEye-1 satellite sensor was successfully launched on September 6, 2008. The satellite, which was launched at Vanderberg Air Force Base, California, provides a resolution of 0.46 meters. The GeoEye-1 Satellite sensor features the most sophisticated technology ever used in a commercial remote sensing system. This newly developed sensor is optimized for large projects, as it can collect over 350,000 square kilometers of pan-sharpened multispectral satellite imagery every day.
GeoEye-1, launched in September 2008, has been flying at an altitude of about 681 kilometers and is capable of producing imagery with a ground sampling distance of 46 centimeters, meaning it can detect objects of that diameter or greater.
During late summer of 2013 the orbit altitude of the GeoEye-1 Satellite sensor was raised to 770 Km / 478 Miles. GeoEye-1 new nadir ground sample distance (GSD) is 46cm compared to the previous GSD of 41cm.
