IMU Analogue output
An Inertial Measurement Unit (IMU) is a 6-DOF system that measures linear and angular motion using a combination of accelerometers and gyroscopes. MEMS based IMUs include a range of precision inertial sensors, including a triaxial acceleration sensor and a triaxial gyroscope.
The IMU outputs acceleration and rotation rate signals in the form of an analog raw signal. Due to the excellent long-term stability and the low noise (bias, scale factor, noise, angular random walk) of the sensors used, it is possible to reliably obtain position changes in all 6 DOFs with high accuracy and repeatability by integrating the analog sensor signals twice.
