MDA, a Maxar Company, Announces Successful Launch of Canada’s RADARSAT Constellation Mission

Sponsored by Businesswire

MDA, a Maxar company (NYSE: MAXR) (TSX: MAXR), announced today that the
Constellation Mission (RCM) satellites developed by MDA for the Canadian
Space Agency are performing according to plan. The satellites launched
this morning aboard a SpaceX
Falcon 9
rocket from the Vandenberg Air Force Base in California,
and began sending and receiving signals from space. The satellites will
now go through a series of in-orbit manoeuvres and tests before entering
service later this year.

MDA is the prime contractor for the project and was responsible for the
engineering design, construction and testing of the three satellites,
the ground segment and operations development. Launch was provided by
MDA subcontractor SpaceX. MDA is also providing mission operations
services for the first year on orbit, supporting the integration of RCM
into mission-critical activities across the Canadian government.

RCM represents a major enhancement of Canada’s RADARSAT program,
following the successes of RADARSAT-1 and RADARSAT-2. Each spacecraft
payload consists of a Synthetic Aperture Radar (SAR) sensor integrated
with an Automated Identification System (AIS) sensor.

RCM will provide the Government of Canada with enhanced surveillance,
monitoring and management of Canada’s coastal and Arctic regions,
fisheries, icy waterways, agricultural lands, natural resources, climate
and fragile ecosystems, as well as to support highly operational defence
capabilities and global disaster relief efforts. The three-satellite
constellation is capable of scanning the Earth day or night and in any
weather conditions, allowing for daily coverage over Canada’s vast
territory and maritime approaches.

“We are thrilled to see the RCM satellites successfully launched,” said
Mike Greenley, group president of MDA. “The RADARSAT Constellation
Mission builds on the legacy of RADARSAT-1 and RADARSAT-2, and on
Canada’s expertise and leadership in Earth Observation from space.
RADARSAT data has been critical to enhance the Canadian economy and to
ensure sovereignty and security of our vast interests, while
contributing to our role in the international community on issues
impacting our planet.”

was launched in November 1995. It operated for 17 years, well over its
five-year life expectancy, during which it orbited Earth 90,828 times,
travelling over 2 billion kilometres. It was Canada’s first Earth
observation satellite. RADARSAT-1 images supported relief operations in
244 disaster events.

was launched in December 2007 and is still operational today. This
project represents a unique collaboration between government and
industry. MDA owns and operates the satellite and ground segment. The
Canadian Space Agency and MDA jointly funded the construction and launch
of the satellite. The CSA recovers this investment through the supply of
RADARSAT-2 data to the Government of Canada during the lifetime of the

The RCM satellite constellation has a design life of seven years
providing benefits both for Canadians and for the entire world, as well
as growing Canada’s global leadership position in space-based radar
Earth observation.
