WorldView-2 satellite, launched in October 2009, is the first commercial 8-band multispectral high-resolution satellite
Operating at an altitude of 770 km, WorldView-2 provides panchromatic imaging with a resolution of 46 cm of m and multispectral imaging with a resolution of 1.85 m. The average revisit interval for WorldView-2 is 1.1 days, and daily coverage of 8-band imaging is 1 million km²
Operator: DigitalGlobe (США).
