ViaSat Airborne Broadband Ku-band Satcom Deployed by U.S. Special Forces for Real Time Data and Video Communications : System Quickly Configures C-130 Aircraft for U.S. Special Forces Missions

CARLSBAD, Calif. (EMWNews) July 16, 2008 —

ViaSat Inc. (Nasdaq:VSAT) has provided the U.S. Special Forces with a

new airborne broadband satcom system to greatly enhance its warfighting

capabilities. The system is already in use in the Middle East and

coverage areas will expand as more terminals and hubs are delivered.

This new operational capability, an extension of the ArcLight®

mobile broadband system, is installed on C-130 aircraft, primarily for

sending high resolution video back to higher command authorities for

further analysis and identification. It also provides two way broadband

communications for a variety of command and control needs. The U.S.

Special Operations Command (USSOCOM) is the first military organization

to use the new satcom system which taps into the ArcLight commercial

broadband satellite network for private business jets and maritime

applications operated by ViaSat and SES Americom Government Services.

The C-130 satcom system is built around the advanced ArcLight modem and

networking technology using a spread spectrum waveform to enable the use

of mobile satellite antennas as small as 29 centimeters in diameter. The

antenna is enclosed in a radome attached to a redesigned emergency

escape hatch. In a few minutes, operators can configure an aircraft for

their specific mission without any permanent aircraft alterations, then

quickly return the aircraft to its normal configuration when the mission

is complete, while maintaining safety-of-flight integrity. The U.S. Air

Force-certified hatch-mount terminal enables secure access to Department

of Defense wide area networks at raw data rates up to 10 Mbps inbound

and 512 kbps outbound while airborne.

“This system was first demonstrated by the

U.S. Joint Forces Command, was JITC Certified, declared ready for

network-centric operations, and now is operational on these USSOCOM

aircraft,” said Larry Taylor, ViaSat

Government Satcom director of business development. “This

new broadband service provides a much greater level of real-time

situational awareness while leveraging commercial satcom technology to

greatly reduce operational and support costs compared to other systems.”

The ArcLight spread spectrum technology assures regulatory compliance

with FCC and ITU rules governing adjacent satellite interference.

Licensed in over 25 countries, the system delivers a terrestrial

broadband experience to aircraft, small maritime vessels, European

trains, and ground on-the-move vehicles using commercial Ku-band

satellites. It can also easily adapt to other frequency bands.
