Product functions and relevant technical parameters
1.1 Composition and function
The 16488HA inertial measurement unit is a complete inertial system with a built-in three-axis gyroscope and a three-axis accelerometer, which is used to measure the three-axis angular rate, acceleration and other parameters of the carrier, and output the data after error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.) through SPI according to the communication protocol.
