ViaSat Will Add Capability to Air Force Joint Communication Simulator under New Task Order


CARLSBAD, Calif., May 13, 2008 (BUSINESS WIRE) -- ViaSat Inc. (Nasdaq:VSAT) has received a $3.97 million Task Order (TO) for modification of the Joint Communication Simulator (JCS) under an Indefinite Delivery/Indefinite Quantity (ID/IQ) contract from the U.S. Air Force. The JCS enables accurate analysis of communication system performance without the expense of in-flight testing. This award continues to expand the simulation system capabilities to include new operating modes and communication, navigation and intelligence signals, including integrating Link 16 into government RF communication simulators.


"Link 16 is the preferred tactical data link between coalition forces and this development increases the utility of the JCS by adding this key communication signal to the RF simulation environment," said Greg Norton, program manager, ViaSat Simulation Systems Group.


For more than 10 years ViaSat has been developing and delivering communication, navigation, and identification (CNI) test systems to DoD customers. RF stimulation from ViaSat goes beyond ordinary simulation and computer modeling techniques to actually stimulate the avionics environment with real signals of RF energy, including RF jamming and background signals.


JCS systems are located at the Air Force Flight Test Center's (AFFTC) Electronic Warfare Avionics Test and Integration Complex (ATIC) at Edwards Air Force Base (EAFB), California and the Air Combat Environment Test and Evaluation Facility (ACETEF) at the Naval Air Warfare Center - Aircraft Division (NAWC-AD), Maryland.
