High-Resolution GeoEye-1 Satellite

GeoEye-1 the super-sharp Earth-imaging satellite was launched into orbit on 6th of September from Vandenberg Air Force Base on the Central California coast. A Delta 2 rocket carrying the GeoEye-1 satellite lifted off at 11:50 a.m. Video on the GeoEye Web site showed the satellite separating from the rocket moments later on its way to an eventual polar orbit. The satellite makers say GeoEye-1 has the highest resolution of any commercial imaging system. It can collect images from orbit with enough detail to show home plate on a baseball diamond. The company says the satellite's imaging services will be sold for uses that could range from environmental mapping to agriculture and defence. GeoEye-1 was lifted into a near-polar orbit by a 12-story-tall United Launch Alliance Delta II 7420-10 configuration launch vehicle. The launch vehicle and associate support services were procured by Boeing Launch Services. The company expects to offer imagery and products to customers in the mid- to late-October timeframe. GeoEye-1, designed and built by General Dynamics Advanced Information Systems, is the world's highest resolution commercial imaging satellite.

Designed to take color images of the Earth from 423 miles (681 kilometers) in space and moving at a speed of about four-and-a-half miles (seven kilometers) per second, the satellite will make 15 earth orbits per day and collect imagery with its ITT-built imaging system that can distinguish objects on the Earth's surface as small as 0.41-meters (16 inches) in size in the panchromatic (black and white) mode. The 4,300-pound satellite will also be able to collect multispectral or color imagery at 1.65-meter ground resolution. While the satellite will be able to collect imagery at 0.41-meters, GeoEye's operating license from NOAA requires re-sampling the imagery to half-meter resolution for all customers not explicitly granted a waiver by the U.S. Government. The satellite will be able to see an object the size of home plate on a baseball diamond but also map the location of an object that size to within about nine feet (three meters) of its true location on the surface of the Earth without need for ground control points. Together, GeoEye's IKONOS and GeoEye-1 satellites can collect almost one million square kilometers of imagery per day.
