Raytheon
And
Newtec
Helping
To
Tackle
Climate
Change
28
April
2010.
Newtec
announces
today
that
Raytheon
Intelligence
and
Information
Systems
selected
Newtec
to
provide
Newtec’s
Elevation
EL470
DVB-S2
IP
modems
with
FlexACM®
licenses
for
Raytheon’s
satellite
communication
system
upgrade
for
McMurdo
Station,
Antarctica.
McMurdo
Station
is
the
largest
of
the
three
U.S.
Antarctic
Program
(USAP)
research
stations
operated
and
managed
by
the
National
Science
Foundation
(NSF).
The
EL470
modems
are
configured
for
1:1
redundancy
and
were
recently
installed
in
the
satellite
earth
station
facilities
in
both
Antarctica
and
Australia.
The
equipment
is
part
of a
larger
effort
by
Raytheon
to
modernize
and
increase
the
satellite
bandwidth
for
improved
off-continent
communications
needs.
NPOESS
was
designed
to
serve
as
the
nation's
next
generation
low
Earth
orbiting
operational
weather
and
climate
monitoring
system
and
to
provide
timely
and
essential
data
to
civilian
and
military.
The
government
recently
announced
its
plans
to
restructure
NPOESS
and
is
currently
developing
a
transition
plan.
The
NPOESS
system
will
monitor
global
environmental
conditions,
as
well
as
collect
and
disseminate
data
related
to
weather,
atmosphere,
oceans,
and
land
and
near-space
environments.
Two
new
polar
tracking
antennas
are
being
installed
at
McMurdo
Station
to
support
the
down-linking
of
the
NPOESS
weather
data
as
part
of
16
globally-distributed
receive-only
earth
stations
(receptors).
The
NPOSSS
data
will
utilize
the
improved
communications
link
to
transmit
its
data
to
the
weather
processing
centers
in
the
United
States.
" Improvements
to
satellite
communications
from
McMurdo
were
needed
to
support
the
large
amounts
of
data
that
must
be
quickly
delivered
to
the
United
States",
said
Joe
Paciaroni,
NPOESS
Global
Network
and
Infrastructure
(GNI)
Manager
for
Raytheon.
"The
outbound
circuit
can
now
support
up
to
60
Mbps
using
8PSK-2/3
DVB-S2
and
the
inbound
circuit
can
support
up
to
20
Mbps
with
8PSK-3/4
DVB-S2.
Newtec’s
DVB-S2
IP
Modems
offered
Raytheon
the
best
use
of
the
Satcom
link,
so
it
was
a
natural
choice
to
select
the
EL470
for
this
service",
Paciaroni
added.
Newtec’s
FlexACM ®
combines
a
range
of
cutting
edge
technologies
for
implementing
Adaptive
Coding
and
Modulation
(ACM),
traffic
shaping,
payload
compression
and
IP
acceleration
in a
highly
efficient
way
for
IP
trunking
and
IP
backbone
satellite
links.
In
addition
to
doubling
the
capacity
of
an
existing
link,
on
average,
it
also
guarantees
100
%
availability
of
link
reception,
even
when
all
other
systems
are
down
due
to
heavy
rain
fade.
FlexACM
can
be
used
in
point-to-point
and
point-to-multipoint
systems,
in
one
way
(with
terrestrial
return
channels),
as
well
as
two-way
configurations
(with
the
return
channel
also
over
satellite).
It
can
be
used
to
upgrade
existing
satellite
links
without
changing
other
elements
of
the
transmission
chain,
such
as
the
antenna
or
HPA.
The
upgrade
completes
a
four-year
effort
to
modernize
the
electronics
of
the
two
large
NSF
satellite
communications
antennas,
20
miles
distant
from
McMurdo.
The
antennas
are
located
at
NSF’s
Black
Island
Telecommunications
Facility,
a
remote,
wind-swept
island
that
provides
a
clear
view
of
satellites
low
on
the
northern
sky.
The
Black
Island
facility
supports
all
of
NSF’s
off-continent
satellite
communications
for
NSF
funded
USAP
science
research
program
and
staff
operating
from
McMurdo.
Northrop
Grumman
is
the
prime
contractor
and
has
overall
responsibility
for
the
NPOESS
program
development
effort.
Raytheon
is
part
of
the
Northrop
Grumman
Corporation-led
NPOESS
team.
The
Northrop
Grumman
Corporation
patented
SafetyNet™
architecture
consists
of
16
globally
distributed
ground
receptors
being
developed
by
Raytheon
Company.
