OSI Geospatial Submarine WECDIS Software in use onboard Royal Navy Vanguard
Class SSBN

OTTAWA, Sept. 27 /CNW Telbec/ - OSI Geospatial Inc. (TSX: OSI) ("OSI Geospatial") announced today that, after successful sea trials, the first Vanguard Class SSBN has been approved to navigate digitally. As part of the Lockheed Martin UK WECDIS team, OSI Geospatial is the software supplier, and this milestone achievement clearly indicates the confidence that the Royal Navy places in the accuracy, reliability and improvement of operational capability that ECPINS(R) W (Sub) software gives the user.

"This significant event in the RN WECDIS program follows on from our recent announcement of the selection of ECPINS W (Sub) for the Astute program in the UK, which represents yet another example of the maturity and flexibility of our software for the submarine market," said Ken Kirkpatrick, President and CEO. "The Vanguard Class submarine is now the second submarine to be fitted with WECDIS and achieving the highly-acclaimed status as a digital navigation platform. With more than 400 ships and submarines now fitted with our solutions and 14 NATO and Allied Naval customers, OSI Geospatial has the widest operational military install base."

About Our Submarine Technology

"Our software is also able to be installed into legacy as well as future submarine hardware environments bringing our total of submarine customers to 7", said Jim Davison, Director Sales & Marketing. "OSI Geospatial's submarine WECDIS solutions are the most advanced, operationally proven and widely deployed today. Our systems have also been successfully interfaced to existing submarine Combat Management Systems and the unique features of ECPINS W (Sub) provide the submariner with a clear tactical advantage across all submarine platforms from SSBN through to Air Independent Propulsion system submarines. The Company's solutions for the submarine market are the most cost effective and lowest risk, which is why we continue to see this market expand. OSI Geospatial will be presenting a paper at the forthcoming Submarine Operations and Requirements Conference in London allowing future customers an opportunity to learn more about this technology."
