Pléiades 1A and Pléiades 1B, launched on December 17, 2011 and December 2, 2012 respectively, operate as a constellation in the same orbit, phased 180° apart. They provide 5 acquisition modes: Target, Strip Mapping, Tri-stereo, Corridor and Persistent Surveillance. The image location accuracy is from 1 m to 3 m. Because the satellite has been […]

Read MoreLaunched on September 6, 2008, GeoEye collects images at 41 cm panchromatic and 1.65 m multispectral resolution. It geolocates features to less than 5 m. During the summer of 2013, the orbit altitude was raised to 770 km from 681 km. Its new nadir ground sample distance is 46 cm compared to the previous 41 […]
Read MoreThe IKONOS, launched on September 24, 1999, is the world’s first commercial satellite to collect panchromatic (black-and-white) images with .80 m resolution and multispectral (color) imagery with 3.2-meter resolution. Imagery from the panchromatic and multispectral sensors can be merged to create .80 m color imagery (pan-sharpened). From a 423-mile-high orbit, IKONOS has a revisit time […]
Read MoreLaunched on May 18, 2012, Kompsat-3 (Korean Multipurpose Satellite), is an optical high-resolution observation mission of KARI (Korea Aerospace Research Institute). It collects data in the afternoon at 13:30 and has the highest bits (14) per pixel to provide better performance for spectral analysis. Spatial Resolution: Panchromatic: 70cm Multispectral: 2.8m Spectral Resolution: Panchromatic: (450 to […]
Read MoreLaunched on June 19, 2014, Deimos-2 satellite is high resolution (75 cm pan-sharpened) multispectral optical satellite, fully owned and operated by Elecnor Deimos Imaging, a Spanish private company. The satellite has 4 imaging modes: Single Strip Imaging, Multi-pointing Imaging, Single Pass Stereo Imaging, and Tessellation Imaging Spatial Resolution: Panchromatic: 75cm Multispectral: 2.8m Spectral Resolution: Panchromatic: […]
Read MoreQuickBird, launched on October 18, 2001, offered 61 cm resolution panchromatic data and 2.44 m resolution multispectral data with high geolocational accuracy. QuickBird was operating at an altitude of 400 km and continued in a gradual descent until its end of mission life at an altitude of 300 km on February 19, 2015. Spatial Resolution: […]
Read MoreWorldView-1, launched on September 18 2007, is the first earth observations satellite owned by DigitalGlobe. The high-capacity, panchromatic imaging system features half-meter resolution imagery. Operating at an altitude of 496 km, WorldView-1 has an average revisit time of 1.7 days and is capable of collecting over one million km square per day of half-meter imagery. […]
Read MoreSPOT-7 (Systeme Pour l’Observation de la Terre — Satellite for Observation of Earth), launched on June 30, 2014, and SPOT-6 launched on September 9, 2012 are operated by AirBus Defence and Space, France. These 2 satellites fly on a co-orbit with the high resolution Pleiades 1A and 1B constellation. With location accuracy better than 10 […]
Read MoreSPOT-5 (Systeme Pour l’Observation de la Terre — Satellite for Observation of Earth), was launched on May 3, 2001 and decommissioned as of March 31, 2015. The coverage of 60 km x 60 km per scene was a key asset in medium-scale mapping at 1:25,000. Spatial Resolution: Panchromatic: 2.5-5m Multispectral: 5m Spectral Resolution: Panchromatic: (480 to […]
