High Accuracy Imu System Inertial Reference System Imu Inertial Measurement Unit for Navigation IMU400
IMU400 Inertial Measurement Unit is breakthrough, fully integrated
inertial solutions that combine the latest MEMS sensors technology.
Fully calibrated, temperature compensated, mathematically aligned
to an orthogonal coordinate system, IMU400 demonstrates less than
30 deg/hr gyroscopes and 0.001g accelerometers bias in-run
stability with very low noise and high reliability.
Continuous Built-in Test (BIT), configurable communications
protocols, electromagnetic interference (EMI) protection, and
flexible input power requirements make IMU400 easy to use in a wide
range of higher order integrated system applications.

What is Basic principle of inertial navigation?
Given the ability to measure the acceleration of vehicle it would
be possible to calculate the change in velocity and position by
performing successive mathematical integrations of the acceleration
with respect to time.
In order to navigate with respect to our inertial reference frame,
it is necessary to keep track of the direction in which the
accelerometers are pointing.
Rotational motion of the body with respect to inertial reference
frame may be sensed using gyroscopic sensors that are used to
determine the orientation of the accelerometers at all times. Given
this information it is possible to resolve the accelerations into
the reference frame before the integration process takes place.
