Description of the satellite WorldView-2 satellite
The WorldView-2 satellite was designed to perform high-quality commercial Earth observation. It is designed to provide very detailed images of the Earth's high-resolution surface for various purposes, including mapping, geodesy, resource management, urban planning, environmental monitoring and other applications.The WorldView-2 satellite was launched on October 8, 2009. It was launched by Delta II from the Vandenberg launch site in California, United States.
The orbit of the satellite is about 770 kilometres above the ground.
The resolution of the WorldView-2 satellite is 46 centimetres, allowing for very detailed images of the Earth's surface.
The satellite operates in eight multispectral ranges, including visible, infrared and near infrared spectrums. This ensures that various aspects of the Earth's surface can be analysed on the basis of their physical properties and condition.
The features of the WorldView-2 satellite include the high rate of data collection, the ability to switch rapidly between surveying modes and the accuracy of positioning and navigation.
WorldView-2 is developed by the American company DigitalGlobal (now Maksar Technologies).
