    • Background Experience Established in October 2002 in Munich In March 2003 EUSI started operating the German Regional Operations Center (GEROC) for IKONOS Since April 2010 EUSI is operating the European Direct Access Facility (EDAF) for WorldView-2 Both facilities are at the German Aerospace Center (DLR) near Munich have local tasking, data reception, and processing11/4/2011 Proprietary and Confidential 4
    • Network• WorldView Global Alliance with DigitalGlobe – The world’s largest commercial remote sensing company, delivering the highest- quality, most accurate satellite imagery – Owns and operates three earth imaging satellites: Quickbird, WorldView-1 and WorldView-2 – WorldView-3 under construction – scheduled for launch in 2014• Technology partner of DLR (German Aerospace Center) – Joint operation of EUSI‘s WorldView DAF – Project support• 47 Resellers in 33 Countries• Alliance covering 63 countries in Europe, North Africa and CIS• Prime VHR data supplier to Europe – Framework agreements with European Commission and EU/UN organizations – National MoDs

    • WorldView-2 • Very high resolution •46 cm* panchromatic at nadir • The most spectral diversity commercially available •1.84 m* resolution at nadir •4 standard colors: blue, green, red, near-IR1 •4 new colors: coastal, yellow, red edge, and near-IR2 • Highly accurate geo-location accuracy • Typically ~5m (depending on terrain) • High capacity over a broad range of collection types •16.4 km width imaging swath (wider than any competitor) •Bi-directional scanning •Rapid retargeting using Control Moment Gyros (>2x faster than any competitor) •2199 gigabits on-board storage •Frequent revisits at high resolution enabled by higher altitude •1.1 days at 1 m GSD or less •3.7 days at 20°off-nadir or less (52 cm GSD)* Distribution and use of imagery at better than .50 m GSD pan and 2.0 m GSD multispectral is subject to prior approval by the U.S. Government.11/4/2011 Proprietary and Confidential 13
    • Advantages of Local Tasking 1. Feedback during imaging planning last minute information incorporated into collection plan 2. Real-time weather information used up to minutes prior to pass 3. Very detailed imaging planning possible up to 4 hrs spent per pass to optimize collection plan11/4/2011 Proprietary and Confidential 14
