  1. 1. IKONOS Satellites and Their SpecificationThe IKONOS Satellite is a high-resolution satellite operated by GeoEye. Itscapabilities include capturing a 3.2m multispectral, Near-Infrared (NIR)/0.82mpanchromatic resolution at nadir. Its applications include both urban and ruralmapping of natural resources and of natural disasters, tax mapping, agricultureand forestry analysis, mining, engineering, construction, and change detection. Itcan yield relevant data for nearly all aspects of environmental study. IKONOSimages have also been procured by SIC for use in the media and motion pictureindustries, providing aerial views and satellite photos for many areas around theworld. Its high resolution data makes an integral contribution to homelandsecurity, coastal monitoring and facilitates 3D Terrain analysis.IKONOS SATELLITE SYSTEM: SENSOR CHARACTERISTICSLaunch Date 24 September 1999 at Vandenberg Air Force Base, California, USAOperational Life Over 7 yearsOrbit 98.1 degree, sun synchronousSpeed on Orbit 7.5 kilometers per secondSpeed Over the Ground 6.8 kilometers per secondRevolutions Around the Earth 14.7, every 24 hoursAltitude 681 kilometersResolution at Nadir 0.82 meters panchromatic; 3.2 meters multispectralResolution 26° Off-Nadir 1.0 meter panchromatic; 4.0 meters multispectralImage Swath 11.3 kilometers at nadir; 13.8 kilometers at 26° off-nadirEquator Crossing Time Nominally 10:30 AM solar timeRevisit Time Approximately 3 days at 40° latitudeDynamic Range 11-bits per pixelImage Bands Panchromatic, blue, green, red, near IR
