| Overview |
GeoEye's next-generation GeoEye-1 (formerly OrbView 5) satellite system will orbit 660 km above the Earth in a sun-synchronous orbit while collecting imagery at 0.41 meter resolution in the panchromatic (black and white) mode, and 1.64 meter resolution in the multispectral (color) mode. When OrbView-5 joins the company's OrbView 3 satellite in mid 2008, the constellation will collect more than 1.2 million square kilometer of imagery per day with a combined revisit period of less than 1.5 days for any geographic target.
Principal partners for the development and launch of the OrbView-5 satellite include General Dynamics (formerly Spectrum Astro), Kodak/ITT Industries and Boeing Launch Services. Partners for the ground segment include IBM and MacDonald, Dettwiler and Associates of Canada.
NGA announced on September 30, 2004 that it has selected ORBIMAGE as its Next View second vendor after a competitive selection process conducted over the last six months. The contract, awarded September 30, 2004, runs through September 30, 2008 and will provide ORBIMAGE with both long-term revenue commitments as well as capital for the development of OrbView-5, ORBIMAGE's next-generation high-resolution imaging satellite. The contract, known as Next View ORBIMAGE, also assures NGA of greater access and priority to high-resolution commercial satellite imagery. |

| About GeoEye-1 |
The GeoEye-1 Satellite sensor was developed by GeoEye and will feature the most sophisticated technology ever used in a commercial remote sensing system.
GeoEye-1 will be capable of acquiring image data at 0.41 meter panchromatic (B&W) and 1.65 meter multispectral resolution. GeoEye-1 will also feature a revisit time of less than three days, as well as the ability to locate an object within just three meters of its physical location.
This newly developed sensor will also be optimized for large projects, as it will be able to collect over 350,000 square kilometers of pan-sharpened multispectral satellite imagery every day. |
