ViaSat C-130 Aircraft Hatch-Mount Satellite Antenna for Broadband Ku-band Communications Passes Certification Testing

ViaSat Inc. (Nasdaq:VSAT) has delivered a hatch-mounted Ku-band satcom antenna for C-130 aircraft that has received air worthiness certification from U.S. Air Force authorities at Warner Robbins Air Force Base. The hatch mounted antenna enables configuration of aircraft for 2-way broadband communication access to terrestrial services and the GIG without any permanent modifications. Within minutes, ground crews can configure the aircraft for a specific mission, and then easily return the plane to normal transport configuration when the mission is complete. The newly-certified antenna enables use of an airborne satcom system to access wide area Department of Defense SIPRNet and NIPRNet networks at data rates up to 10 Mbps inbound and 512 kbps outbound while airborne and en route to mission destinations.

CARLSBAD, Calif. (BusinessWire EON) March 15, 2007 -- ViaSat Inc. (Nasdaq:VSAT) has delivered a hatch-mounted Ku-band satcom antenna for C-130 aircraft that has received air worthiness certification from U.S. Air Force authorities at Warner Robbins Air Force Base. The hatch mounted antenna enables configuration of aircraft for 2-way broadband communication access to terrestrial services and the GIG without any permanent modifications. Within minutes, ground crews can configure the aircraft for a specific mission, and then easily return the plane to normal transport configuration when the mission is complete. The newly-certified antenna enables use of an airborne satcom system to access wide area Department of Defense SIPRNet and NIPRNet networks at data rates up to 10 Mbps inbound and 512 kbps outbound while airborne and en route to mission destinations.

The small, low-profile antenna is enabled by the ViaSat ArcLight® spread spectrum waveform, a major breakthrough in satellite communications for the Command and Control on the Move (C20TM) system that was recently certified by the Joint Interoperability Test Command (JITC). C2OTM is a commercial, off-the-shelf Ku-band satcom system that can be easily installed on ground vehicles, fixed- and rotary-wing aircraft, small-surface ships, and any mobile platform requiring broadband IP access on the move. The ViaSat waveform overcomes the challenges of satellite blockage from obstructions such as buildings, trees or helicopter blades.
