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

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

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 type s


* 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

2. Effect of Real-Time Weather

• No weather forecast 30 % good 70 % bad images

Average collection results over Europe using differ ent levels of weather information:


• Weather forecast files 50 % good 50 % bad images

• Real-time weather 80 % good 20 % bad images

Faster Synoptic Collects

WorldView-2 is the fastest for synoptic collects of targets and large areas while large areas while providing 8 spectral bands

4711/4/2011

Note: Information based on WV-1 collects and all collections < 45 degrees off-nadir

Faster Synoptic Collects

DigitalGlobe Proprietary

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.
