1,Product functions and relevant technical parameters
1.1 Composition and function
The 16488C multi-degree-of-freedom inertial measurement unit is a complete inertial system with a three-axis gyroscope, a three-axis accelerometer, a three-axis magnetometer and a pressure sensor, which is used to measure the three-axis angular rate, acceleration, three-axis magnetic field, air pressure and other parameters of the carrier. Output the data after error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.) through SPI or URAT according to the communication protocol.
