World's Highest-Resolution Satellite Imagery
"Half-meter resolution image of Khalifa Sports City, Doha,
Qatar, was collected by the GeoEye-1 satellite on January
Images captured at the GeoEye-1's maximum ground resolution of 0.41 meters are captured using a panchromatic (black-and-white) sensor; the GeoEye-1's maximum color ground resolution is 1.65 meters (or about 64 inches)--the satellite's electronics can process 700-million pixels-per-second. The GeoEye-1 is in a sun-synchronous, polar-orbit, traveling at 7.5km/sec (about 16,800-mph), and it can collect "up to 700,000 square kilometers in a single day, an area about the size of Texas, and in the multispectral mode 350,000 square kilometers per day; the equivalent of photographing in color the entire State of New Mexico." The GeoEye-1 makes just under 15 orbits per day (it has a 98-minute period) and can revisit virtually any location in less than three days.
GeoEye-1 started delivering imagery to commercial customers as of February 5, and now that the NGA has certified GeoEye-1 for its needs, the satellite is officially delivering images to the NGA as of today. Now that it is officially online for the NGA, GeoEye-1 will begin generating $12.5 million per month in revenue from the NGA for GeoEye. GeoEye's chief operating officer, Bill Schuster, stated, "we are already working on the advanced camera and camera electronics for GeoEye-2 and look forward to continuing to serve NGA with next-generation capabilities."
