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.

The inertial measurement unit (hereinafter referred to as the ‘product’) uses a three-axis integrated fiber optic gyroscope and a three-axis MEMS accelerometer as sensitive devices for angular velocity and visual acceleration, respectively, to measure the angular velocity and acceleration information of each axis of the carrier coordinate system. The angular velocity and acceleration information are sent to the acquisition and processing circuit, and after sampling, filtering, and error compensation, the angular velocity and visual acceleration information are output to the outside world. The product has high precision, small size, light weight, and strong adaptability, suitable for attitude control and inertial navigation.
