ViaSat Successfully Demonstrates Mesh Satcom COTM Over Ka-band On Optus C1
November
1,
2010
ViaSat
Inc.
has
successfully
demonstrated
full-mesh
satellite
communications
at
Ka-band
between
an
Australian
Army
deployable
1.0-metre
Compact
Transmit
Receive
Suite
(CTRS)
terminal
located
at
the
Defence
Science
and
Technology
Organisation
(DSTO)
and
a
48-cm
communication-on-the-move
(COTM)
terminal
located
at
BAE
Systems
Australia
using
a
ViaSat
LinkWay®(S2)
MF-TDMA
satellite
modem.
This
demonstration
further
shows
the
ability
of
the
LinkWay(S2)
modem
to
simultaneously
support
satellite
communications
with
fixed
site,
at-the-halt,
and
on-the-move
terminals
within
a
single
tactical
LinkWay
network.
The
full-duplex
mesh
connection
streamed
high-definition
video
simultaneously
in
both
directions
between
remote
sites
while
the
mobile
satcom
antenna
was
exercised
on a
multi-axis,
full
motion
platform
using
the
steerable
Ka-band
spot
beam
on
the
Optus
C1
satellite.
The
LinkWay(S2)
master
reference
terminal
for
the
demonstration
originated
from
a
fixed
terminal
with
a
DVB-S
overlay
sourced
from
another
Ka
transponder
on
Optus
C1.
"This
is
the
first
demonstration
of
Ka-band
broadband
communications-on-the-move
using
standard,
off-the-shelf
LinkWay(S2)
modems,"
said
Peter
Weissmann,
ViaSat
business
development
manager
for
Australia
and
New
Zealand.
"This
demonstration
follows
several
very
successful
vehicular
and
airborne
Ku-band
mobile
satcom
demonstrations
recently
conducted
in
the
U.S.
It
was
also
the
first
demonstration
of
the
optional
DVB
overlay
in a
mobile
setting,
showing
the
versatility
of
the
LinkWay(S2)
platform."
