Research
and
development
programs
at ATA
Sensors
continue
to
provide
improvements
to
current
products
and add
new
products
to the
lineup.
MERG
Gyroscope
Project
ATA’s
patented
Magnetohydrodynamic
(MHD)
technology
is being
expanded
even
further
in the MHD
Effect
Rate
Gyroscope,
or MERG
development
project.
This
next
generation
gyroscope
will, as
other
ATA
sensor
products
have
done,
bring to
market
a sensor
that
will be
much
more
rugged
and less
expensive
than
anything
offered
by
competitors.
Initially,
the
design
will
provide
for
inertial
navigation
systems
with
drift
rates of
less
than 20
degrees
per hour
in small
package
sizes
with low
mass and
low
power
consumption.
The
angular
rate
frequency
response
of the
MERG is
from DC
to over
1000 Hz.
North
Finding
Project
Existing
MHD
based
sensors
have the
ability
to
detect
the
rotation
of the
earth
and
derive
true
North
direction
to an
accuracy
of 3
milliradians,
making
precise
azimuth
systems
possible
based on
the
NorthFinder
design.
This
product
will
work
where
magnetic
interference
or
extreme
latitudes
prevent
use of
the
magnetic
compasses,
and lack
of
motion
precludes
use of
GPS for
determining
direction.
Possible
applications
are in
surveying,
mining,
military
direction
finding
other
applications
requiring
precise
knowledge
of true
north.
ARS-06
MHD
Angular
Rate
Sensor
- Preliminary
A
new
sensor,
the
ARS-06,
is being
developed
and will
be on
the
market
shortly.
This new
sensor
will
take the
place of
the now
obsolete
ARS-04.
The
ARS-06,
while
being
about
the size
of the
ARS-04,
has
performance
near the
industry
standard
ARS-01
and the
ability
to
withstand
a
10,000G
load
without
damage.
The
ruggedness,
combined
with
superior
performance
and
small
size of
the
ARS-06
will
make it
a
popular
addition
to ATA’s
lineup.
Linear
EM
Actuators
ATA is
continuing
to build
on it's
reputation
for
innovation
and
performance-focused
components
with the
introduction
of
custom
linear
EM
actuators.
Our
high-bandwidth,
low
mass,
space-qualified
ACT-32
actuators
have the
highest
force
per amp
available
on the
market.
One
customer
closed a
1200 Hz
control
loop on
a large
(6"
x
9")
beryllium
mirror
using
this
custom
design.
Other
actuator
applications
include
platform
stabilization
and
driving
motion
on
custom
test
tables.
MIRU-II
Appendix
B
Technical
Abstract
The
Air
Force
has
identified
the need
for a
small,
inexpensive
inertial
attitude
reference
system
that
functions
as a
two-axis
optical
reference
in high
performance
aircraft
applications.
Applied
Technology
Associates
(ATA)
proposes
the
Magnetohydrodynamic
(MHD)
Inertial
Reference
Unit
(MIRU)
to meet
the
requirement.

Inertial
Angular
Actuator
Imparting
torque
to
platforms
or other
objects
to
induce
or
cancel
motion
has been
a
consistently
challenging
requirement
faced by
many
developers.
ATA has
developed
an
inertial
angular
actuator
that
serves
as it's
own
angular
sensor!
This
device
is
extremely
rugged,
has
kilohertz
bandwidth,
and uses
no power
and
produces
no
disturbances
when not
in use
(unlike
conventional
momentum
wheels).
The
collocation
of the
sensor
and
actuator
will
enable
unprecedented
cancellation
of
disturbances.
