The U3700 series is an IMU/VRU/AHRS sensor composed of an array MEMS-IMU and a magnetometer. It is equipped with self-developed adaptive extended Kalman filtering, 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.
The U3700 series sensors transmit data through various interfaces such as UART (RS-232/TTL), RS-485, CAN, and have rich user configurations. The U3700 series can synchronize with the system through external triggering, and also align with external systems such as radar and camera time through synchronous output function. Multi-functional upper computer (GUI) can help quickly evaluate products, including but not limited to module configuration, data display, firmware upgrade, data recording, etc.
