IMU sensor fusion for orientation estimation

The U16495-C is equipped with built - in three - axis gyroscopes and three - axis accelerometers, which are used to measure the three - axis angular rates and three - axis accelerations of the carrier. The data from the gyroscopes and accelerometers, which have undergone error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.), are output through a serial port according to the agreed communication protocol. They can be used for precise navigation, control, and dynamic measurement of the carrier. This product uses high - precision MEMS inertial devices, featuring small size, strong overload resistance, high reliability, and high hardness, and it is capable of accurately measuring the angular rate and acceleration information of a moving carrier even in harsh environments.

U4500 series sensors are composed of high-performance tactical-grade MEMS-IMU designed IMU/VRU/MRU/AHRS/INS systems, and are equipped with independently developed adaptive extended Kalman filtering, IMU noise dynamic analysis algorithms, heave estimation algorithms, carrier motion state analysis algorithms, and GNSS fusion algorithms, which can provide users with accurate position, attitude, velocity and other information. U4500 series sensors transmit data through UART/CAN interfaces and have rich user configurations. (A transceiver needs to be connected externally for CAN) U4500 series can synchronize with the system through external triggering, can receive UTC time, and can also align time with external systems such as radars and cameras through the synchronous output function. A multi-functional upper computer (GUI) can help quickly evaluate the product, and these functions include but are not limited to module configuration, data display, firmware upgrade, data recording, etc.

U4200 series is an IMU/VRU/AHRS sensor composed of tactical-grade MEMS-IMU and magnetometer. It is equipped with independently developed adaptive extended Kalman filtering, IMU noise dynamic analysis algorithm, and carrier motion state analysis algorithm, which can meet the accuracy of attitude angles under high dynamics and reduce the drift of heading angles. Each sensor undergoes precise compensation before leaving the factory, including temperature, zero bias, scale factor, and cross-axis. U4200 series sensors perform data transmission through various interfaces such as RS232, RS422, and CAN, and have rich user configurations. U4200 series can be synchronized with the system through external triggering, and can also achieve time alignment with external systems such as radars and cameras through the synchronous output function. The multifunctional upper computer (GUI) can help quickly evaluate the product, and these functions include but are not limited to module configuration, data display, firmware upgrade, data recording, etc.

The U6488 series IMU are equipped with built - in three - axis gyroscopes and three - axis accelerometers, which are used to measure the three - axis angular rates and three - axis accelerations of the carrier. The data from the gyroscopes and accelerometers, which have undergone error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.), are output through a serial port according to the agreed communication protocol. They can be used for precise navigation, control, and dynamic measurement of the carrier. This product uses high - precision MEMS inertial devices, featuring small size, strong overload resistance, high reliability, and high hardness, and it is capable of accurately measuring the angular rate and acceleration information of a moving carrier even in harsh environments. The U6488 series includes four models: U6488-B, U6488-C, U6488-D, and U6488-E. The appearance and interface performance of the four models are consistent. Except for U6488-E, all of them are equipped with built - in three - axis magnetometers and digital barometers.
