CAMBRIDGE, ON, May 14 /CNW/ - exactEarth Ltd., the data services subsidiary of COM DEV International Ltd., today announced that it will present results of a recent test of its space-based Automatic Identification System (S-AIS) detection capabilities at next week's annual meeting of the Radio Technical Commission for Maritime Services (RTCM).
In sea trials conducted earlier this year near Hawaii, exactEarth's S-AIS technology was evaluated for its ability to detect AIS signals transmitted from new types of battery-operated devices, called AIS-SARTs, that will be carried in life rafts or by individuals in distress in the water. Most of the transmissions were broadcast at a strength of only 1 Watt, compared to 12.5 Watts for a standard Class A AIS transmission from a ship.
Using its NTS demonstration nano-satellite, exactEarth was successful in detecting signals from all five of the source devices that were broadcasting during the sea trials. Unique among all participants, exactEarth correctly determined that one of the transponders was "spoofing" its signals by altering its transmitted identification every few seconds.
"We are very pleased to have our technology validated in an independent test, especially considering the particular challenges involved in these sea trials," said Peter Mabson, President of exactEarth. "The AIS signals were less than one-tenth as strong as the ones our satellites are designed to detect, and the transmitters were bobbing with the waves at water level rather than emanating from the relative stability of a large vessel."
exactEarth was invited to participate in these sea trials, organized by the U.S. Coast Guard and the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA). These organizations are evaluating the use of AIS signals as a complement to other search and rescue technologies, to take advantage of the fact that over 70,000 vessels are already actively transmitting and receiving on this frequency.
RTCM is an international non-profit scientific, professional and educational organization comprised of over 120 member organizations. exactEarth's Jim King will participate in panel discussions on AIS developments and vessel monitoring at the RTCM annual meeting in San Diego, CA on Tuesday, May 18, 2010.
