The
ADIS16488HA
inertial
measurement
unit
is
a
complete
inertial
system
featuring
a
built-in
three-axis
gyroscope
and
three-axis
accelerometer.
This
high-performance
IMU
measures
three-axis
angular
rate,
acceleration,
and
other
critical
parameters
of
the
carrier.
The
unit
outputs
error-compensated
data
(including
temperature
compensation,
installation
misalignment
angle
compensation,
and
nonlinear
compensation)
through
SPI
according
to
the
communication
protocol.
