GeoEye-1 Satellite Imagery / Sensor Specifications - Remote Sensing Satellite Image Tutorial
GeoEye-1 Satellite Imagery / Sensor Specifications

Satellite Imaging Corporation acquires and processes imagery from the groundbreaking GeoEye-1 satellite sensor. The satellite sensor launched on September 6, 2008 (view launch video).

About the GeoEye-1 Satellite

GeoEye-1 Satellite Sensor

The GeoEye-1 Satellite sensor was developed by GeoEye and features the most sophisticated technology ever used in a commercial remote sensing system.

GeoEye-1 is capable of acquiring image data at 0.41 meter panchromatic (B&W) and 1.65 meter multispectral resolution. It also features 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 is optimized for large projects, as it can collect over 350,000 square kilometers of pan-sharpened multispectral satellite imagery every day.

Imaging Angle Capable of imaging in any direction
Revisit Frequency at 684 km Altitude (40° Latitude Target)
Max Pan GSD (m) Off Nadir Look Angle (deg) Average Revisit (days)
0.42 10 8.3
0.50 28 2.8
0.59 35 2.1
Daily Monoscopic Area Collection Capacity Up to 700,000 sq km/day (270,271 sq mi/day) of pan area (about the size of Texas). Up to 350,000 sq km/day (135,135 sq mi/day) of pan-sharpened multispectral area (about the size of New Mexico)

* Data reflects ground sample distance resolution at Nadir for exclusive use by the U.S. government and any foreign government that the U.S. government may designate. Imagery sold to commercial customers will be resampled to 0.5-meter resolution. GeoEye’s current operating license with NOAA does not permit the commercial sale of imagery below 0.5-meter resolution.
