  • Page 2 BW-AH525 High precision CAN bus AHRS Introduction BW-AH525 Attitude and Heading Reference System （AHRS） is a high performance, low cost inertial measurement device that measures the attitude parameters (roll and pitch), angular velocity, acceleration information and heading angle of the dynamic carrier. The attitude and angular velocity deviations are estimated by a 6-state Kalman filter with appropriate gain, which is suitable for dynamic measurement of navigation and positioning.

  • Page 5: Product Installation

    BW-AH525 High precision CAN bus AHRS Product installation The correct installation method can avoid measurement errors, and the following points should be taken when installing the sensor: First of all, to ensure that the sensor mounting surface is completely close to the measured surface, the measured surface should be as horizontal as possible, and there should be no angle shown in Figure A and Figure C.
  • Page 6 BW-AH525 High precision CAN bus AHRS Measurement installation The azimuth reference system has been calibrated at the factory. In places where the influence of the magnetic field environment is small, it is not necessary to perform environmental calibration when using it, and it can be used directly.
  • Page 7 BW-AH525 High precision CAN bus AHRS Debugging software Since there is a dedicated CAN receiving device for data communication with CAN interface products, the software is a CAN acquisition device. The software used is not the same, so there is no corresponding software. Let's take the CAN receiver module and product communication adopted by our company as an example: Configure the CAN baud rate and parameters as follows: The receiving and sending areas are set as follows:...
  • Page 8 BW-AH525 High precision CAN bus AHRS Protocol The CAN includes 8 bytes, and the data byte is not enough to be followed by 0. Sending the first byte 0x40 indicates a write command, and returning the first byte 0x40 indicates that the write was successful. The ID is the CAN communication node number.
