WorldView-2 lowers the satellite's orbit sharpens its image-taking ability
Published: 2011-10-27 Source by: Original
For DigitalGlobe, the NGA cash investment will mainly be to enhance the company's ground infrastructure for capturing and delivering satellite imagery. That will be especially necessary since NGA is asking DigitalGlobe to lower its WorldView-2 satellite's orbit from 770 kilometers to 680 kilometers by mid-2011, with an option to order a further orbit lowering, to 496 kilometers, starting in October 2013.Lowering the satellite's orbit sharpens its image-taking ability but reduces its field of view.
