VANCOUVER, BRITISH COLUMBIA -- (MARKET WIRE) -- 04/26/07 -- OSI Geospatial Inc. (TSX: OSI)(OTCBB: OSIIF) announced today that its U.S. Systems Operations has signed a US $500,000 contract to provide the U.S. Navy with military navigation systems. The systems will be installed on 12 new vessels that are being built to support homeland defense initiatives.

"This is a very important win for us, as the U.S. government is planning to build hundreds of small vessels over the next three to five years to support homeland defense and other military requirements. This contract positions us well for further wins," said Ken Kirkpatrick, president and CEO. "We are pleased that our world leading ECPINS®-M navigation system has been selected for this project."

The U.S. government and many other governments around the world are committing substantial resources towards coastal and harbor defense initiatives.
