Rugged Ahrs Module Orientation Sensor Ahrs Attitude Heading
Reference System for Unmanned Surface Vessel AHRS5000
Product Description
AHRS5000 Attitude and Heading Reference System (AHRS) is a high
performance inertial measurement system, AHRS5000 offers a range of
fully calibrated inertial measurements including acceleration,
angular rate, magnetic field, deltaTheta and deltaVelocity vectors.
It can also output computed orientation estimates including Euler
angles (pitch, roll, and heading (yaw)), rotation matrix and
quaternion. All quantities are fully temperature compensated and
are mathematically aligned to an orthogonal coordinate system. The
angular rate quantities are further corrected for g-sensitivity and
scale factor non-linearity to third order.
AHRS5000 has two working modes: AHRS or VG. The system enjoys small
size and light weight and rugged enclosure, it is widely applied in
movement control system, stability and control for aircraft, ship
and vehicle, inertial navigation and guidance, ROV underwater
navigation, etc.
AHRS5000 architecture has been carefully designed to substantially
eliminate common sources of error such as hysteresis induced by
temperature changes and sensitivity to supply voltage variations.
Gyro drift is eliminated in AHRS mode by referencing magnetic North
and Earth’s gravity and compensating for gyro bias. On-board coning
and sculling compensation allows for use of lower data output rates
while maintaining performance of a fast internal sampling rate.

FAQ
What applications of Attitude and Heading Reference System Works?
AHRS sensors are typically used in one of three ways. First of all
they can be used as an instrument to provide flight data recording
of the orientation of the platform as a function of time. Secondly
an AHRS can be used for platform stabilization. The angular rate
outputs can be directly tied into a control loop to maintain
platform stability. An AHRS can also be used as an attitude control
system. Aircraft, helicopters, quad-rotors, blimps, and even
underwater robotic vehicles all can benefit from the use of an AHRS
to form a closed-loop attitude control system. The angular rate
outputs at a high bandwidth along with the estimated orientation
angles make it possible to command a platform directly with desired
attitude angles. The quaternion output that many units provide make
singularity free attitude control a reality for many applications.
