GeoEye-1 is an observation satellite from the American company GeoEye .
Mission and Payload
The launch of the satellite took place on September 6, 2008 from Vandenberg Air Force Base with a Delta II rocket .
It is located on a 681 km high sun-synchronous orbit with an orbit inclination of 98.1 °. In the visible range (with panchromatic recording) it achieves a spatial resolution of less than 0.5 m, with color images or images in the infrared (with multispectral recording) around 1.65 m. Stereoscopic images are also possible. The swath width is 15.2 km, whereby the cameras can take pictures up to 60 ° outside the vertical. GeoEye-1 records an area twice the size of Germany every day and sends the data to the ground stations for processing. In addition, the 1955 kg satellite has an internal storage capacity of 1 Terabit and a transmission channel with 150 or 740 Mbit / s in the X-band . Customers include the US Department of Agriculture , Google and the National Geospatial Intelligence Agency . The service life of the satellite is planned to be more than seven years, with the fuel supply being designed for 15 years.
The manufacturer is General Dynamics Advanced Information Systems (AIS).
The contract to build GeoEye-2 was awarded to Lockheed Martin. The launch of this successor was planned for spring 2013, but was canceled after the company GeoEye merged with competitor DigitalGlobe . The satellite has been stored indefinitely.
On July 31, 2014, DigitalGlobe announced that GeoEye-2 will be renamed WorldView-4 and that it is scheduled to launch in 2016. The launch took place on November 11, 2016.
