TCS Awarded New Location Patent

New Patent Is TCS' 6th Assisted GPS-Related Patent

ANNAPOLIS, MD -- (MARKET WIRE) -- December 27, 2006 -- TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced the U.S. Patent and Trademark Office has issued patent number 7,154,438 titled, "Prioritized List of Potential Culled Satellite Ephemeris Information for Quick, Accurate Assisted Locating Satellite Location Determination."

The patent enables a wireless subscriber's location to be determined more quickly and more reliably than traditional assisted Global Positioning System (A-GPS) methods. It addresses specific geographic constraints -- such as topography or buildings -- that a subscriber may face when trying to secure a location fix. Additionally, the patent technology has the capability to enable wireless carriers to offer a better experience to their customers for all of the location applications they offer.

With this latest patent, TCS now has six A-GPS patents as part of its patent portfolio. A-GPS usage is expected to show strong growth in the future as GSM-based carriers deploy A-GPS handsets and infrastructure for their precise location requirements. ABI Research recently stated that GPS-enabled Location-Based Services (LBS) users will reach 315 million by 2011, up from 12 million in 2006.

"TCS has been a leader in assisted GPS in the Code Division Multiple Access (CDMA) marketplace and will continue this leadership in the Global System for Mobile communication (GSM)-based marketplace," stated Tim Lorello, Senior Vice President and Chief Marketing Officer for TCS. "North American and European carriers will likely start deploying assisted GPS solutions in 2007, and TCS will be looked to as a preferred vendor of its patent protected assisted GPS infrastructure."


Today, there are 29 satellites in the GPS network, each moving around the Earth approximately six times per day. As a user moves his or her wireless GPS device from one location to another, the locations relative to the satellites change. GPS devices attempting to determine the user's position can only communicate with a limited number of the total GPS satellites at any given time. In the past, the time required for lock-in and location determination using a conventional GPS receiver could take several minutes, which is unsatisfactory for many applications, and a longer time than the average wireless phone call's duration. Rapid, high-strength links to the satellites directly in line in a narrow cone path can expedite the time to lock in a location.

The "Prioritized List of Potential Culled Satellite Ephemeris Information for Quick, Accurate Assisted Locating Satellite Location Determination" patent provides a method and apparatus for more dependable location solutions by overcoming the vagaries of Low Earth Orbit (LEO) satellite visibility and local topography. The invention provides for a primary group of satellites and a secondary group of satellites should any of the primary satellites not be available for a location fix. The method and apparatus of culling the satellites can be performed in a wireless communications base station and a mobile device.
