Viasat’s First ViaSat-3
Satellite Achieves Major Milestone
June 7, 2021
Viasat Inc. announced the
first satellite in its ViaSat-3 global
constellation, which will serve the Americas and
the surrounding oceans regions, has reached a
major milestone with completion of payload
integration and performance testing, and
shipment to the Boeing Satellite Systems
facility in El Segundo, Calif.
The payload will be
integrated with the bus module, which is based
on Boeing’s proven 702 platform, and the
satellite will then undergo a complete series of
environmental testing to simulate the rigors of
launch and operation in the harsh environment of
space. Launch is targeted for early calendar
year 2022.
“This is an incredibly
exciting time for Viasat as the first of the
three high-powered ViaSat-3 satellites in our
global constellation enters the final stages of
production,” said Dave Ryan, president, Viasat
Space & Commercial Networks. “Once complete, we
will be ready to put the world’s
highest-capacity single satellite into
geostationary orbit to serve the world by
delivering broadband to the hardest-to-reach
areas anywhere — on the ground, in the air and
at sea.”
Each ViaSat-3 satellite is
expected to generate over 20kW of payload power,
making it among the highest-power commercial
satellites ever built. Just three of these
satellites will cover nearly the entire globe,
and are expected to deliver over 3,000 Gigabits
per second (Gbps) of capacity — or 3 Terabits
per second (Tbps) total — for 15 years or more.
The ViaSat-3 constellation is anticipated to
have roughly eight times more capacity than
Viasat’s current fleet combined. Vast amounts of
bandwidth are needed to address increased demand
for high speed internet access — particularly in
the video streaming realm. ViaSat-3 represents a
major advancement in Viasat’s mission to extend
broadband internet service to the many places
around the world that don’t have it.
Ryan added, “While the
payload was assembled at Viasat’s Tempe, AZ
facility, the effort was company-wide. From
Tempe, to the antenna expertise in Duluth (GA),
to Germantown (MD) for their software and
systems engineering know-how and other offices
around the world from Chennai, India to
Lausanne, Switzerland as well as at our Carlsbad
headquarters, all of these teams worked together
to come up with a totally unique way to not only
build this spacecraft, but to test it in record
time.”
