Star Navigation Announces Settlement of Litigation and Assignment of Patent Rights

TORONTO, May 20 - Star Navigation Systems Group Ltd. (TSX-V: SNA) ("Star" or the "Company"), a leading edge technology company focused on providing Aerospace Solutions, both hardware and software platforms to assist aviation operators worldwide, is pleased to announce that it has reached a settlement in the action commenced by its former President, Hilary Vieira. As part of the settlement, Mr. Vieira has agreed to dismiss his suit against Star, Viraf S. Kapadia and former Star director Peter Verbeek, and provide a full release of all claims made by him in that action. Star has in turn agreed to dismiss its counterclaim against Mr. Vieira and provide a release to him of its claims. (See press releases dated May 17 and September 18, 2007). (Star's claims against Aeromechanical Services Ltd. (TSX-V: AMA) and others are not part of the settlement).

Mr. Vieira has also agreed to fully and completely cooperate and provide full disclosure to Star and Mr. Kapadia in any current or future litigation in relation to U.S. Patent No. 7,113,852 ("the ISMS Patent"), including the litigation currently outstanding with Aeromechanical Services Ltd. ("AMS") and others.

Mr. Vieira has further agreed to not have any commercial relations with Aeromechanical Services Ltd., I-Trax International Corp., Kerrie Acquisition Corporation or any of their associates or subsidiaries and, for a period of two years and will not have any commercial relations with any of Stars' direct competitors, their associates or subsidiaries.

Pursuant to this settlement, the Company has agreed to pay to Mr. Vieira $116,000 in cash and issue to him 1,000,000 common shares at a deemed price of $0.06 per share. The Company had accrued a greater amount as being payable to Mr. Vieira for his past services. The Company will therefore eliminate over $500,000 in debt from its balance sheet.

In a separate transaction, Mr. Vieira has agreed to assign all of his interest in the ISMS Patent to Viraf S. Kapadia, CEO of Star and Co-Inventor of the ISMS Patent. Upon completion of registration of documents at the U.S. Patent and Trademark Office, Mr. Kapadia will be the sole and unrestricted owner of the ISMS Patent. No consideration was paid by Star with respect to this transaction. Star owns the exclusive worldwide license to the ISMS Patent, upon which Star's Terrastar: RTM(TM) technology is based.
