ACCESS MISSION DATA

At the time of its launch, GeoEye-1 was the world's highest-resolution commercial Earth-imaging satellite.

About GeoEye-1

GeoEye-1 is an Earth-imaging satellite operated by Maxar of the United States which launched 6 September 2008 and remains operational.

It is part of ESA's Third Party Missions Programme, in which ESA has an agreement with European Space Imaging (EUSI) to distribute data products from the mission.

GeoEye Mission Parameters
Orbit Height 681 km
Orbit Type Sun-synchronous, 10:30 am descending node
Orbit Period 99 mins
Revisit time 1.7 days at 1-metre GSD resolution
4.6 days at 25° off-nadir (0.59 m GSD)

GeoEye-1 Objectives

The satellite imagery is used for a variety of purposes, including but not limited to defence, disaster response, air and marine transportation, oil and gas exploration, mining production and exploration, mapping of remote regions, location-based services, insurance and risk management, agricultural crop management and more.

GeoEye-1 can revisit any point on Earth once every three days, or even sooner depending on latitude and elevation angle.

GeoEye Imaging System (GIS)

GIS is optimised for large projects as it can collect over 350,000 square kilometres of VHR satellite imagery every day. Images are collected at 0.41 m panchromatic and 1.65 m 4-band multi-spectral data in 15.2 km swaths.

DATA DESCRIPTION

ESA is offering, for scientific research and application development, access to Full archive and New Tasking of GeoEye-1 data upon submission and acceptance of project proposal. These products are available as part of the Maxar Standard Satellite Imagery products.

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore, only a limited amount of products can be made available to each project.

The following collection is available:

Moreover, ESA offers registered users access through the Online Dissemination server to the following data collection:

  • GeoEye-1 ESA archive: Products that ESA collected over the years. The dataset regularly grows as ESA gathers new products.
