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.
