FY-AHRS-2000B Installation Instructions

FY-AHRS-2000B is a high-performance strap down inertial navigation system that can
measure any point of orientation of the entire locomotive and vehicle in the 3D space. AHRS
could make high-precision positioning for any stationary or moving objects with angular velocity,
even short magnetic interference will not affect the heading accuracy of the AHRS. The system
can be carried out AHRS magnetic field calibration, to eliminate the hard and soft iron materials
motorcycles offset caused by magnetic fields.

Features:

1、Using high-performance all solid-state three-axis accelerometer, three-axis angular rate

sensors and three-axis magnetic field sensor.

2、Three axis 360-degree all-dimensional output of the attitude and heading, attitude and heading

data on a static accuracy of less than 0.5 degrees, the dynamic accuracy of less than 2
degrees.

3、 Built-in sensor auto-calibrate, can automatically compensate for the interference of

temperature drift, noise, external magnetic field, etc.

4、Super long time stability and fast dynamic response.

Application:

 Ground Transportation
 Robots
 Aircraft
 Video Camera ect.

The AHRS includes three gyroscopes, three accelerometers and three magnetic field
meters. Real-time measure three axial angular velocity, acceleration, and magnetic field strength.
After the processing by the internal microprocessor, the AHRS outputs drift-free attitude and
heading information, the three-dimensional acceleration, three-dimensional angular velocity,
three-dimensional geomagnetic field, which have been compared and checked-off.
