At the time of its launch, GeoEye-1 was the world's highest resolution commercial Earth-imaging satellite. [15] GeoEye-1 was manufactured in Gilbert, Arizona, by General Dynamics and the first image was returned on 7 October of Kutztown University in Pennsylvania. [16]
SBIRS GEO-1 in orbit In the mid 1950s, the United States began development of the first space-based missile detection system; the Missile Defense Alarm System (MIDAS), in low Earth orbit . Following the end of the MIDAS programme, plans to deploy an operational system led to the Integrated Missile Early Warning Satellite programme (IMEWS ...
The first SBIRS GEO satellite of the SBIRS program, SBIRS GEO-1, was successfully launched from Cape Canaveral on an Atlas V launch vehicle on 7 May 2011. [8] In June 2014, Lockheed Martin was contracted by the USAF to build SBIRS GEO-5 and SBIRS GEO-6, at a cost of US$1.86 billion. [5] [9] [10]
Geostationary satellites are launched via a temporary orbit, and then placed in a "slot" above a particular point on the Earth's surface. The satellite requires periodic station-keeping to maintain its position. Modern retired geostationary satellites are placed in a higher graveyard orbit to avoid collisions.
A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Popularly or loosely, the term "geosynchronous" may be used to mean geostationary. [1] Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, [2] or geostationary Earth orbit. [3]
GEO-1 may refer to: . the first in a series of Global Environment Outlook reports issued in 1997 by the United Nations Environmental Program; Geosynchronous satellite USA-230, also known as SBIRS High GEO 1, the first in a series of space surveillance satellites launched in 2011 as part of the United States Air Force's Space-Based Infrared System
The GeoEye-2 satellite is designed to provide panchromatic images at a highest resolution of 0.31 meters per pixel (12.2 in/px), and multispectral images at 1.24 meters per pixel (48.8 in/px). [20] The spacecraft was designed and built by Lockheed Martin, [ 21 ] while the camera payload was provided by ITT Corporation .
