RADARSAT-2 READIED to Support PROPOSED Tandem Mission with RADARSAT-3

Saint-Hubert, Quebec, June 20, 2001 – The Canadian Space Agency announced
today the awarding of two contracts totaling $ 6.7 million to MacDonald,
Dettwiler and Associates Ltd. (TSE: MDA). MDA will, under the first contract
for a total amount of $5.7 million, implement specific modifications to the
RADARSAT-2 spacecraft to support a proposed tandem mission with RADARSAT-3.
The second contract awarded to the Richmond-based company, worth $1 million,
provides for the implementation of the second phase of a Mission Definition
Study including the preparation of a detailed implementation plan for
RADARSAT-3.

The RADARSAT-2 and 3 tandem mission will provide the capability to capture
high-resolution three-dimensional images of the Earth’s surface on an
ongoing basis, and will maintain Canada’s leadership in the application of
Synthetic Aperture Radar (SAR) technology.

“This innovative project led jointly by the Canadian Space Agency and
MacDonald, Dettwiler and Associates Ltd. will strengthen Canada’s leadership
and expertise in the growing field of Earth Observation”, said the
Honourable Brian Tobin, Minister of Industry and Minister responsible for
the Canadian Space Agency. “Moreover, this new use of Synthetic Aperture
Radar (SAR) technology offers great potential to expand our reach in new
sectors of activity, thus strengthening Canada’s ability to effectively
compete in global markets”.

“Right now, with these contract awards from the Canadian Space Agency, we
have a unique window of opportunity to implement these improvements to
RADARSAT-2 and prepare the way for a potential future tandem mission with
RADARSAT-3″, said Daniel Friedmann, President and CEO of MDA. The tandem
mission would provide us with an important data source and allow us to
produce for the first time, complete 3-D elevation mapping of the entire
planet”.

The launch of RADARSAT-2 is now expected for late 2003.
