U3500 series is an IMU/VRU/AHRS sensor composed of high-performance MEMS-IMU, magnetometer, and enhanced single axis gyroscope. It is equipped with self-developed adaptive extended Kalman filter, IMU noise dynamic analysis algorithm, and carrier motion state analysis algorithm, which can meet the accuracy of attitude angle under high dynamic conditions and reduce heading angle drift. Every sensor undergoes fine compensation including temperature, zero bias, scaling factor, and cross axis before leaving the factory. U3500 series sensors transmit data through UART interface and have rich user configurations. If a CAN interface is required, users should integrate the CAN transceiver circuit themselves. U3500 series can be synchronized with the system through external triggering, and can also align with external systems such as radar and camera time through synchronous output function. A multifunctional upper computer (GUI) can help quickly evaluate products, including but not limited to module configuration, data display, firmware upgrade, data recording, etc.
