WorldView 2 [DigitalGlobe]
WorldView 2 is an earth observation satellite operating at an altitude of 770 kilometers. WorldView 2 enables DigitalGlobe to offer half-meter panchromatic resolution and 1.8 meter multispectral resolution. The WorldView 2 system allows DigitalGlobe to substantially expand its imagery product offerings to both commercial and international customers with a more commercially desirable, higher performance product. Added spectral diversity provides the ability to perform precise change detection and mapping. WorldView 2 incorporates the industry standard four multispectral bands (red, blue, green and near-infrared) and also includes four new bands (coastal, yellow, red edge, and near-infrared).
The WorldView 2 telescope has a 110 cm aperture and flys at a higher altitude of 770 km. It provides the same panchromatic half-meter resolution imagery as WorldView 1, in addition to 1.8 meter multispectral resolution imagery.
In 19 July 2016, Worldview-2 was involved in a debris-causing event, but the satellite remained operational.
In August 2010 a mostly identical WolrdView 3 was ordered for launch in 2014. This satellite has an additional infra-red capability. From its lower orbit of 617 km, it has a ground resolution of 0.31 m.
