WorldView-1

WorldView-1 is a commercial earth observation satellite from Ball Aerospace in the USA. It was launched on 18 September 2007 from Vandenberg Air Force Base on a Delta II rocket.

WorldView is to deliver from a height of 496 km images at a resolution of 0.5 m ( panchromatic). In addition, the three -axis stabilized satellite and the data analysis is very well prepared to accommodate changes in an area over previous recordings or stereo images of a region. Are sold the pictures in cooperation with the firm DigitalGlobe, which already operates a satellite for similar tasks with QuickBird.

Launched in October 2009, WorldView-2 also has the ability to absorb multi-spectral images in eight spectral bands with a resolution of 1.8 m.
