GeoEye launches high-resolution satellite

Liftoff from Vandenberg

WASHINGTON, Sept 6 (Reuters) – GeoEye Inc said it successfully launched into space on Saturday its new GeoEye-1 satellite, which will provide the U.S. government, Google Earth users and others the highest-resolution commercial color satellite imagery on the market.

“It was a picture-perfect launch and we’ve now gotten confirmation that … we have commanded the satellite and it has responded,” GeoEye Chief Executive Matthew O’Connell told Reuters in a telephone interview from Vandenberg Air Force Base in California, where the satellite was launched at 11:50 a.m. PDT (1850 GMT).

“Everybody is now slapping high fives,” he said, adding that it would take 30 to 45 days before the company calibrates the camera aboard the satellite and receives imagery.

GeoEye-1 will be able to capture images at .41 metres (16 inches) resolution in black and white and 1.65 metres (5.5 feet) in color, but under current government rules, the company can only offer the public half-metre (1.64 feet) images.

The satellite will take digital images of the Earth from 423 miles (681 km) and moving at a speed of about 4 1/2 miles (7 km) per second.

O’Connell said the $502 million satellite, built partly with money from the U.S. National Geospatial-Intelligence Agency, would “open up a lot of opportunities” for the GeoEye, and capped four years of work on the spacecraft.

GeoEye will again make history with the upcoming launch of GeoEye-1—the world’s highest resolution commercial earth-imaging satellite.

GeoEye-1 will be equipped with the most sophisticated technology ever used in a commercial satellite system. It will offer unprecedented spatial resolution by simultaneously acquiring 0.41-meter panchromatic and 1.65-meter multispectral imagery. The detail and geospatial accuracy of GeoEye-1 imagery will further expand applications for satellite imagery in every commercial and government market sector.
