GuiLin FeiYu Electronic Technology Co., Ltd FY-AHRS-1200A 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.
GuiLin FeiYu Electronic Technology Co., Ltd 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.
GuiLin FeiYu Electronic Technology Co., Ltd Specification FY-AHRS-1200A Remark Refresh Rate（Hz） 1~100 The default refresh rate is 20Hz Initialization Time（sec） 3 Performance Heading Output Range（deg） 0~360 Accuracy（deg） ±1 Resolution（deg） 0.1 Compensation and Correction Attitude Roll output range（deg） ±180 Pitch output range（deg） ±90 Static Accuracy（deg） ＜0.2 Dynamic accuracy（deg RMS） ＜2 Resolution（deg） 0.
GuiLin FeiYu Electronic Technology Co., Ltd Weight（g） 50 1、Hardware Installation FY-AHRS-1200A should be installed on a stable platform; the installation of the surface should be parallel with the ground as far as possible when still placed on the platform, and keep it away from the magnetic field effects as far as possible. Magnetic objects must avoid being included. For example: car engines, electric motors, audio speakers, steel, iron and steel nuts or bolts.
GuiLin FeiYu Electronic Technology Co., Ltd Select the serial port used to connect in the "Port" field, such as: "COM1"; in the "Rate" field select the baud rate as "19200"; FY-AHRS-1200A connected to the default wave special rate of 19200, a start-byte, 8 data bytes, a Stop byte, no parity, either hardware or software no "handshake." Baud rate can be changed by command.
GuiLin FeiYu Electronic Technology Co., Ltd Select the menu "Show" - “electronic compass display ", you can switch to two dimensions compass view, its will indicating the real time course. At the main interface of AHRS testing software, you can configure the output serial baud rate, the output data refresh rate, the output data content, etc, and you also can set the baseline calibration and the magnetic field calibration of the sensors inside the FY-AHRS-1200A. GuiLin FeiYu Electronic Technology Co.
GuiLin FeiYu Electronic Technology Co., Ltd 4、Magnetic field calibration FY-AHRS-1200A will be started magnetic compensation calibration procedures once the installation finished. The magnetic field compensation process in the module's firmware determines the magnetic field calibration impact of the installation of platform, so even if the FY-AHRS-1200A is installed on the steel device (for example, a vehicle), its still can provide accurate readings.
GuiLin FeiYu Electronic Technology Co., Ltd The magnetic field calibration process will show the current rotation angle by drawing the circle. You must clockwise rotate FY-AHRS-1200A continuously until the end of the amendment. If the drawn circumference is significantly distortion, its may coursed by the overlarge external magnetic interference or there are problems in the process of rotation, so you must re-calibrate.
