The ADIS16488HA inertial measurement unit is a complete inertial system featuring a built-in three-axis gyroscope and three-axis accelerometer. This high-performance IMU measures three-axis angular rate, acceleration, and other critical parameters of the carrier. The unit outputs error-compensated data (including temperature compensation, installation misalignment angle compensation, and nonlinear compensation) through SPI according to the communication protocol.
