COM DEV Successfully Demonstrates Advanced Space-Based AIS Technology

    Validation satellite achieves one year of on-orbit operations

    CAMBRIDGE, ON, April 28 /CNW/ - COM DEV International Ltd. (TSX:CDV)
today announced that its first experimental satellite, NTS, has successfully
completed one year in orbit, validating COM DEV's high-performance detection
capability for its advanced space-based AIS (Automatic Identification System)
technology. This technology enables the highly accurate tracking and
monitoring of maritime traffic from pole to pole and across the globe, even in
areas of high shipping density. Launched on April 28, 2008, NTS has now mapped
global shipping traffic many times over and has provided the technical
foundation for an operational system which is currently under construction.
Initial operations of this system will commence in 2010.
    "Our demonstration satellite has shown that our proprietary technology is
uniquely capable of reliably detecting and de-colliding large numbers of AIS
signals in the antenna field of view. The result is an ability to secure a
high level of vessel detection on a global scale with the minimum number of
spacecraft. This is an important performance characteristic as AIS
transmissions are being sent simultaneously from literally thousands of ships
that could be in the field of view of a passing satellite at any one time,"
said John Keating, CEO of COM DEV. "We believe this capability and vessel data
will be of great interest to maritime authorities around the globe. For a
country like Canada with a vast coastline and an increasing interest in
monitoring maritime activity in the Arctic, this technology would make it
possible for the first time to keep track of ships within or approaching
territorial waters."
    The success of the NTS mission represents the culmination of more than
five years of focused system and technology development. NTS, an eight
kilogram nanosatellite orbiting every 90 minutes at an altitude of 630 km in a
polar sun-synchronous orbit, was launched to validate COM DEV's advanced
space-based AIS detection technology as a precursor to the deployment of a
constellation of full-performance AIS satellites. The first phase of this
complete operational system is currently under construction and is expected to
be launched in early 2010. This operational system will provide a
comprehensive global AIS monitoring capability to competent maritime
authorities around the world. The constellation will provide near real-time
information on the identity, location and movements of marine vessels that can
be used to establish a vessel traffic management system, protect sovereignty
and security interests, improve maritime safety, and enhance monitoring of
fisheries and the environment.
    All ocean-going vessels, and vessels larger than 300 tons, are required
by the International Maritime Organization to transmit AIS signals. Until now,
however, the data has been collected primarily by shore-based and ship-borne
receivers where range is limited to approximately 50 nautical miles. A fully
operational space-based AIS system would offer unprecedented visibility into
global maritime activity. Using data collected by NTS, COM DEV has generated
the first-ever map of the distribution of worldwide AIS ship traffic. COM DEV
is currently evaluating alternatives for commercializing its AIS solution.
