Background Experience
Established in October 2002 in Munich
In March 2003 EUSI started operating theGerman Regional Operations Center (GEROC) for IKONOS
Since April 2010 EUSI is operating the
11/4/2011 Proprietary and Confidential4
Since April 2010 EUSI is operating theEuropean Direct Access Facility (EDAF) for WorldView-2
Both facilitiesare at the German Aerospace Center (DLR) near Munichhave local tasking, data reception, and processing
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• 47 Resellers in 33 Countries
• Alliance covering 63 countries in Europe, North Afr ica and CIS
• Prime VHR data supplier to Europe– Framework agreements with European Commission and EU/UN organizations– National MoDs

• 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 type s
11/4/2011 Proprietary and Confidential13
* 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.
• High capacity over a broad range of collection type s•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 hig her altitude •1.1 days at 1 m GSD or less •3.7 days at 20°off-nadir or less (52 cm GSD)
Advantages of Local Tasking
1. Feedback during imaging planninglast minute information incorporated into collection plan
2. Real-time weather information

2. Real-time weather informationused up to minutes prior to pass
3. Very detailed imaging planning possibleup to 4 hrs spent per pass to optimize collection plan

In summary...
• EUSI is the only operator performing local tasking for the European region.
• Local tasking provides flexibility and a higher chance of successful collections.successful collections.
• WV-2‘s collection capacity and speed is unmatched
• Data rich ....new applications continually being researched.
