ANNAPOLIS, MD--(Marketwire - February 26, 2008) - TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced that two executives have been selected to speak at this week's SATELLITE 2008 Conference and Exhibition taking place February 25-28, 2008, at the Walter E. Washington Convention Center, Washington, D.C. In addition, TCS will showcase its latest satellite technology innovations on the show floor in booth #627.

With more than 40 sessions addressing broadcast, military, teleport, emerging regions, mobile satellite services, and satellite financing, the SATELLITE 2008 Conference and Exhibition attracts a broad spectrum of satellite professionals who utilize the technology for military, broadcast, enterprise applications.

The following provides details on the TCS speaking engagements:

--   Non-Stop Telco Networks: The Satellite-Enabled Proposition
     Wednesday, February 27, 10:15 - 11:30 a.m.
     Tim Lorello, Senior Vice President and Chief Marketing Officer,
     TeleCommunication Systems, Inc.

     Interconnecting satellite with terrestrial networks to provide
     advanced, uninterruptible services for telco customers is the next
     step in providing risk mitigation in telecom networks. In non-stop
     telco networks, the satellite fail-over fully complements the
     terrestrial network, increasing total network availability and
     mitigating the risk of outages.

--   Satellites Serving the Public Interest: Safety, Security and Service
     Wednesday, February 27, 4:30 - 5:45 p.m.
     Steve Anspach, Vice President of Engineering and Technology,
     TeleCommunication Systems, Inc.

     Mobile Satellite Services have played a leading role in the response
     to disasters both in the US and overseas. The FCC has also cited the
     need for emergency backup communications provided by MSS as a key
     factor in justifying ATC authorizations and has even mandated the
     inclusion of satellite capability in terminals for the new 700MHz
     public-private partnership. European regulators have also highlighted
     the role that new 2GHz MSS networks could play in emergency response.
     This panel will examine the requirements of first responders and what
     MSS providers must do to expand this market in the future.
