The
ARS-12
is
our
most
sensitive
angular
rate
sensor.
Designed
to
eliminate
jitter
from
airborne
and
space
borne
mirrors,
optical
systems
or
lasers,
and
for
accurate
line-of-sight
imaging
platform
stabilization,
the
ARS-12
can
measure
vibrations
and
angular
motions
as low
as 50
nanoradians.
This
product
has very
high
sensitivity
and
a
very low
noise
floor.
The
stainless
steel
housing
and
mounting
plate
make a
rugged
assembly,
able to
operate
accurately
after an
800g
shock
load.
Its
compact
size
and mass
allow
use in very
small
spaces.
The
ARS-12
has a
wide,
usable
frequency
range
from
less
than
1
to
more
than
1,000
Hz. The
ARS-12
is
available
in
three
standard
ranges
for
angular
rate
measurement
and
three
standard
ranges
for
angular
displacement
measurement.
