Canadian Military Signs Contract to Evaluate Suitability for Northern
CAMBRIDGE, ON, Oct. 17 /CNW/ - COM DEV International Ltd. (TSX: CDV), a
leading manufacturer of space hardware subsystems, today announced that the
Company has secured a space flight opportunity to demonstrate an advanced AIS
data detection capability from space. AIS, or Automatic Identification System,
is a VHF broadcast system required aboard major marine vessels to locate and
identify ships at sea. COM DEV has developed satellite payload technology to
solve the traditional challenges associated with space-based collection of AIS
data, and is committed to commercializing it following a series of planned
"Space-based collection of AIS data offers tremendous cost and
performance advantages over existing methods of monitoring marine traffic,"
said John Keating, CEO of COM DEV. "After more than two years of work we have
developed a very promising solution that is ready to be validated under real
world conditions. The potential market for this technology is significant, and
we believe we are well positioned to become world leaders."
The AIS data transmitted by over 68,000 ships worldwide is now collected
primarily from other ships and land-based receivers with a limited range of
approximately 50 nautical miles. A reliable satellite-based collection system
would eliminate the 50-mile limitation as well as the need to build large
numbers of ground stations along the world's coastlines. Existing AIS
transmissions can be received from space, but the primary technical barrier to
a space-based system has been "de-colliding" the cacophony of signals received
simultaneously from hundreds or even thousands of vessels in a satellite field
COM DEV has developed an advanced, proprietary de-collision process
(patent pending) that is capable of separating the multitude of AIS signals
into meaningful information. The satellite payloads, which would fly in
low-earth orbit, would make immediate use of over US $300 million of AIS
equipment already installed by the global shipping industry since mandated in
2004 by the International Maritime Organization. The payloads would include an
onboard encryption system to maintain data security.
COM DEV is conducting a number of tests to validate its AIS technology,
beginning with an aircraft trial in November 2007. The next stage will involve
a prototype test in orbit aboard a nanosatellite currently under construction
at the University of Toronto's Institute for Aerospace Studies Space Flight
Laboratory (UTIAS/SFL) targeted for launch in the second quarter of calendar
2008. The final test will utilize a dedicated microsatellite capable of
demonstrating the full commercial viability of the technology.
The Canadian Department of National Defence (DND), Project Polar Epsilon,
has signed a small contract with COM DEV to obtain data which it will use to
evaluate the results of the trials to assess the suitability of the advanced
AIS system for operational requirements. Polar Epsilon is a DND capital
project to exploit space-based capabilities in support of Canadian Arctic and
marine surveillance. DND is especially interested in the potential for
space-based AIS technology to assist with its objective of monitoring shipping
traffic in the Canadian Arctic.
Maritime and coastal countries around the globe will have the opportunity
to evaluate the system capability as well, and several international agencies
have already expressed an interest in observing the trial results.
COM DEV anticipates that there is a market among various satellite
service providers for over 40 AIS payloads that could be in orbit by 2015. The
processed AIS data from these service providers would be of interest to
national governments, port authorities, coast guards, search and rescue
organizations, shipping companies, and insurance companies, among others.

Automatic Identification System
What is AIS?
Automatic Identification System (AIS) technology relies upon global
navigational positioning systems, shipboard sensors, and digital VHF radio
communication equipment operating according to standardized digital
communication protocols that permit the voiceless exchange of navigation
information between vessels and shore-side vessel traffic centers. The
information is continually updated in near real-time and received by all
AIS-equipped ships and shore stations in its vicinity.
Ships equipped with AIS transponders automatically broadcast basic
information every 2 to 10 seconds about their identity, position, course,
speed, and navigational status.
How is AIS data used?
AIS data helps passing ships avoid collisions, particularly in situations
where they are unable to visually identify one another. AIS data is currently
used by port authorities, coast guards, national governments and others who
have an interest in identifying and locating vessels that enter their
territory. The information can be used to support maritime operations, search
and rescue, and environmental protection as well as security applications.
What ships are required to have AIS onboard?
The International Maritime Organization (IMO) requires AIS equipment to
be installed, generally, on the following vessels: commercial vessels of 65
feet or more in length; tankers; passenger vessels exceeding 150 gross tons or
certificated to carry more than 150 passengers; and vessels exceeding 300
gross tons. Since the IMO requirements went into effect on December 31, 2004,
it is estimated that more than 68,000 vessels worldwide have installed AIS
equipment at a cost of $1,500 to $5,000 per vessel (not including installation
What are the advantages of detecting AIS data from space?
The curvature of the Earth limits the range of surface-based AIS
receivers to approximately 50 nautical miles. An orbiting satellite would be
able to detect AIS signals from a large area at any given time. A modest
constellation of such satellites could effectively cover all navigable waters
on the planet, providing real-time data on the world's maritime activity that
is currently unavailable from any source.
An effective space-based AIS detection system would reduce the need for
ground-based receivers, while utilizing the maritime community's existing
investment in AIS technology.
What are the barriers to space-based AIS?
Today's satellites have no difficulty receiving AIS signals from space;
the challenge lies in distinguishing between the multitude of signals that
would be received at any given moment. Without an advanced method of filtering
and isolating the signals, the satellites would be incapable of returning
How does COM DEV plan to overcome these barriers?
COM DEV International Ltd. has developed a unique de-collision process
(patent pending) whose advanced algorithms are capable of separating the
multitude of AIS signals into meaningful information. The Company is planning
a series of tests that are expected to validate the satellite payload
technology and lead to its full scale commercialization.
What are nanosatellites and microsatellites?
A nanosatellite is a very small, low power satellite (total mass on the
order of 10 kg) that can be inexpensively built and launched into orbit to
test and demonstrate new technology for short missions (approximately one
year). Microsatellites are larger satellites (mass of approximately 100 kg)
that support higher power levels and longer mission durations (up to five
years). Microsatellites can be used to provide commercial-quality services
from low Earth orbit (i.e. orbital altitudes of 500 to 1000 km above Earth).
What is the potential market for space-based AIS data?
Data generated by a space-based AIS system would likely be of interest to
the following organizations:
- National governments, militaries, coastal authorities and surveillance
- Non-governmental organizations such as the International Maritime
Organization and the European Maritime Safety Agency
- Search and rescue organizations
- Shipping companies and their insurers
- Port and maritime operations organizations
- Flag states
