Satellite Overview
Worldview-2
WorldView-2 was launched on Oct 8, 2009 in California. WorldView-2 is currently the only sub-metre satellite to offers 8-band multi-spectral imagery, along with increased agility, accuracy and stereo capability.
GeoEye-1
Launched on Sep 6, 2008, GeoEye-1 has the highest resolution of any commercial imaging system and can collect images with a ground resolution of 0.41 metres in panchromatic mode and at 1.65 metres for multispectral mode. GeoEye-1 offers three metre geolocation accuracy, which means that customers can map natural and man-made features to within 3 metres of their actual location.
Worldview-1
WorldView-1 was launched on Sep 18, 2007. The high-capacity, panchromatic imaging system features half-metre resolution imagery. WorldView-1 has an average revisit time of 1.7 days and is capable of collecting in-track stereo.
Pleiades
The Pléiades system was designed under the French-Italian ORFEO program (Optical & Radar Federated Earth Observation) between 2001 and 2003.
QuickBird
Launched Oct 18, 2001, the QuickBird satellite was the first in a constellation of spacecraft that DigitalGlobe is developing that offers highly accurate, commercial high resolution imagery of Earth.
IKONOS
On 24 September 1999, a new era in satellite remote sensing started with the successful launch of Space Imaging’s IKONOS satellite. IKONOS is the world's first high-resolution commercial satellite to offer 1-metre Earth imagery. Onboard sensors can point both along and across the satellite track, providing a revisit capability of 1-3 days.
SPOT 6
SPOT-6 (Système Pour l’Observation de la Terre) is an optical satellite built by Astrium and was successfully launched on September 9, 2012.
ALOS
Launched on Jan 24, 2006, the Advanced Land Observation Satellite (ALOS) has been developed to contribute to the fields of mapping, precise regional land observation, disaster monitoring and resource surveying.
SPOT 5
SPOT (Satellite Pour l'Observation de la Terre) 5 is a high resolution satellite that was launched in 2002.
SPOT 4
The SPOT constellation are owned and operated by SPOT Image based in Toulouse, France and collect image data down to a pixel resolution of 10 m.
SPOTMaps
SPOTMaps are seamless, uniform, orthorectified regional coverages produced with 2.5 m pan-sharpened colour imagery acquired by the SPOT 5 satellite.
ASTER
Terra, the first Earth Observing System (EOS) satellite was launched on December 18, 1999. ASTER is one of five state-of-the-art instrument sensor systems on-board Terra.
LANDSAT 5&7
The LANDSAT-7 satellite was successfully launched from Vandenburg Air Force Base on April 15, 1999.
TerraSAR-X
TerraSAR-X was launched in 2007 and carries a steerable X-Band SAR sensor which provides a highly accurate, high resolution dataset.
RADARSAT
Spaceborne SAR remote sensing took a giant leap forward with the launch of the RADARSAT satellite in 1995. Table of RADARSAT-1 Tech Specs Table of RADARSAT-2 Tech Specs
PALSAR
The Phased Array L-band Synthetic Aperture Radar (PALSAR) on the ALOS satellite was developed under a joint project between the Japan Aerospace Exploration Agency (JAXA) and the Japan Resources Observation System Organisation (JAROS).
