The IMU400CC is a high performance
solid-state six-degree-of-freedom
(6DOF) Inertial Package intended for
OEM Navigation and Control,
dynamics testing and instrumentation
applications. This high reliability
strap-down inertial system provides
accurate measurement of angular
rate and linear acceleration.
The IMU400CC series product builds
on the performance of the IMU400CB
series. It features higher performance
sensors, including new silicon MEMS
gyroscopes with wider bandwidth and
improved bias stability. New design
features in the IMU400CC series reduce sensitivity to vibration and EMI.

for the effects of temperature, linearity
and misalignment. Fully compensated
angular rate and acceleration outputs
are provided in both analog and
digital (RS-232) formats.
Crossbow continues to manufacture
the IMU300 series, although it recommends the IMU400 for most
applications. Contact Crossbow for
more information on the IMU300.
Each Inertial System comes with a
User’s Manual offering helpful hints
on programming, installation, and
product information. In addition,
Crossbow’s GYRO-VIEW software is
included to assist you in system
development and evaluation, and
allows you to perform data acquisition.

Notes
1 The accelerometer voltage outputs are taken
directly from the accelerometers without
compensation or scaling.
2 The angular rate analog outputs are scaled to
represent degrees/second. Outputs are created
by a D/A converter.
3 Actual output depends on IMU measurement
mode.
