ViaSat Demonstrates In-flight Network Switching Between DoD
And Commercial Satellites
June 13,
2014
In-flight network switching
between a U.S. Government Ka-band Wideband Global SATCOM
satellite and a commercial Ka-band satellite has been
successfully demonstrated by ViaSat Inc. (NASDAQ: VSAT). The
USAF proof of concept flight demonstration was conducted
under a Cooperative Research and Development Agreement
(CRADA) with the Air Force Life Cycle Management Center in
cooperation with Air Mobility Command, 193rd Air National
Guard, MITRE, and MIT Lincoln Laboratory. The body of
observers included representation from U.S. Strategic
Command.
"By providing seamless roaming on
the best available broadband network for enroute military
airborne missions, we can help the government operate and
assure the resilient enterprise network it wants," said
Ken Peterman, VP of
government systems at ViaSat. "This exercise was an
important step in realizing this government vision with the
aircraft transitioning between government and commercial
satellite systems."
In the past year, ViaSat has
significantly expanded the bandwidth on its global airborne
network to address government requirements for broadband ISR
delivery and enroute connectivity. The company offers
multiple service tiers providing increasing levels of
priority access to assure performance when the mission
warrants it.
This test proved a basic premise
underlying the ViaSat "best available broadband network"
concept: That not only is seamless network-switching
possible between government and commercial satellites, but
also between different airborne networks. For this
demonstration the satellite terminals were open government
and industry systems. A government-supplied ThinKom antenna
was integrated with a government-standard MD-1366 EBEM modem
and ViaSat Global Network mobile router systems.
Test results included a number of
key points:
- Successful use of typical VIPSAM (Very Important
Person Special Air Mission) applications such as email,
Internet, messaging, VoIP, file transfer, and VTC.
- Link speeds of up to 6.5 Mbps to and from the
aircraft in flight using the AMC-16 commercial
satellite.
- Use of various data protocols including UDP, TCP,
Web, and FTP to gather performance information.
- Streaming of video, including ISR data and a
high-definition movie.
