SAR Satellites Characteristics Summary
First IMAGES
Greenland
This RADARSAT-2 Standard Quad-Pol image shows the
northern end of the Sermilik fjord on the east coast of
Greenland. The image was acquired December 18, 2007 –
four 4 days after launch and is a composite of the three radar
data channels (HH, VV, HV) displayed in a red-green-blue
colour scheme. The scene is ~ 25km x 50km, with 25m
nominal resolution.
The Fenrisgletscher glacier – a large, slow moving valley
glacier that feeds into the Sermilik fjord - is visible in the upper
right corner of the image. Glaciers in this area produce large
volumes of icebergs that flow out to sea.
This image was acquired early in the commissioning phase,
prior to any adjustment of the radar gain settings.

Iqaluit, Nunavut, Canada
In this RADARSAT-2 Fine Quad-Pol image, the
community of Iqaluit can be seen on the northern
shores of Koojesse inlet - an inlet of Frobisher Bay,
southeast Baffin Island.
The image was acquired January 7, 2008 and is a
composite of the three radar data channels (HH, VV,
HV) displayed in a red-green-blue colour scheme.
The scene is ~25km x 28km, with 8m nominal
resolution.
This image was acquired early in the commissioning
phase, prior to any adjustment of the radar gain
settings.

Vancouver, British Columbia,
Canada
This RADARSAT-2 image of Vancouver
Lower Mainland, was acquired January
6, 2008 using the Ultra-Fine beam
mode, in HH polarization. The scene is ~
20km x 36km, with 3m resolution. The
city of Vancouver is visible in the upper
part of the image.
This image was acquired early in the
commissioning phase, prior to any
adjustment of the radar gain settings.

SOAR - Scientific and Operations
Applications Research
• Partnership between CSA, MDA GSI and the Canada Centre for
Remote Sensing (CCRS)
• Mandate: To further the advancement of RADARSAT-2 applications
in areas where the system strengths provide unique advantage.
• Over 190 research projects around the world will use RADARSAT-2
data to advance applications development
• New SOARs to be announced after commissioning
Recent Events
• MDA has received an offer from Alliant Techsystems (ATK) of the United
States for the purchase of its Space Missions and Earth Observations
businesees, which includes Geospatial Services INC and Radarsat-2;
• There are many shareholder, regulatory and government approvals that will
need to be negotiated in the weeks to come;
• In the interim, the CSA and other government departments and agencies
are reviewing their contracts with MDA to ensure due diligence, and in the
interest of Canadians, full respect of any contractual obligations with the
Canadian Government;
• Government departments and Agencies will draw on a data-allocaiton fund
throughout the life of the R-2 satellite. We fully expect that MDA's
obligations will be fully respected in the future.
