WorldView-2

The WorldView-2 ultra-high-resolution satellite was launched on October 8, 2009 from Vandenberg Air Force Base, California.

The estimated period of its stay in orbit is more than 7 years. DigitalGlobe (USA) receives and distributes WorldView-2 data together with its investors, one of which is the Japanese corporation Hitachi Software Engineering Co. Ltd.

Briefly about the main thing

The WorldView-2 spacecraft was created without raising funds from the federal budget at the own expense of DigitalGlobe and commercial investors. WorldView-2 is the first commercial device with an eight-channel high-resolution spectrometer, which includes traditional spectral channels, as well as four additional ones. They provide higher accuracy in the detailed analysis of vegetation, selection of objects, analysis of the coastline and coastal waters. According to its exact characteristics, WorldView-2 meets the highest requirements. The data obtained from this satellite have an accuracy of not less than 4 m SKO without ground control points.
