PRESS RELEASE: Defense researchers exceed 1 Gbps in SATCOM throughput

ABERDEEN PROVING GROUND, Md. -- Department of Defense
researchers made a giant leap toward increasing satellite
throughput by successfully transmitting an unprecedented 1.3
gigabit per second (Gbps) carrier signal via the Wideband
Global Satellite during the wee hours of the morning, May 19
at the Wahiawa satellite communications, or SATCOM, facility
in Hawaii.
The Army's Research, Development and Engineering
Command's communication-electronics center, or CERDEC,
led the effort, which brought together industry
representatives and all four services in collaboration to
test the achievable throughput using current and emerging
SATCOM capability.
Today's high volume military SATCOM users are tied to the
274 Mbps rate, though there are some reports from industry
partners that they've achieved throughput at just over
600 Mbps, said Rick Dunnegan, CERDEC project lead. This
demonstration doubled that amount and marks the largest data
stream ever processed on wideband military SATCOM.
"Cooperation and desire to succeed from all personnel
from across the services and industry was and is the key to
success in the SATCOM arena," Dunnegan said.
This joint accomplishment was led by the CERDEC Space and
Terrestrial Communications Directorate, whose Joint Satellite
Engineering Center serves as the DoD lead in satellite and
airborne communications research, development, integration,
test and evaluation.
U.S. Marine Corps Tactical Systems Support Activity commander
and staff provided the initial secure transmission site with
independent technical verification personnel. Army Forces
Strategic Command approved the test plan and provided
Wideband Global SATCOM payload access. The team worked
closely with L3 Communications to provided tactical ground
hardware and data system personnel. Navy Wahiawa SATCOM
provided access to a fixed large aperture system facility and
Defense Information Systems Agency provided teleport
connectivity. And the U.S. Air Force's ongoing mission of
monitoring and maintaining the MILSATCOM satellite platforms
are functioning properly was done at normal tempo leaving
adequate time to perform the tests.
