IMU570 inertial navigation unit is composed of three-axis gyroscope, three-axis acceleration, temperature sensor and signal processing circuit. The three-axis angular rate of the carrier is measured, and the three angular rate data after error compensation (including temperature compensation, installation misalignment compensation, non-linear compensation, etc.) are output through RS422 serial port according to the agreed communication protocol. The product adopts differential gyroscope structure, effectively restrains the influence of linear acceleration and vibration, and adopts full temperature compensation to suit the harsh environment of industrial application.

Note:
integrated inertial navigation system has not this configuration and needs to be suspended.
External trigger sources need to be specially configured according to requirements. The default IMU integrated inertial navigation system has not this configuration and needs to be suspended.
IMU570 contains three DOF gyroscopes, representing three axes of spatial coordinate system, namely X, Y and Z. The X axis positive is directed forward from the connector to the middle mounting hole of the sticker, the Y axis positive is directed right to the IMU, and the Z axis positive is directed downward to the bottom of the IMU, as shown in Figure 1.
