On the Interpretation of 3D Gyroscope Measurements

Figure 1

Angular orientation systematic error that arises from erroneously interpreting three simultaneous rotations measured using a 3D gyroscope as sequential rotations. For all examples presented, the sensor rotates for 360° in one second. The examples differ with respect to the sampling frequency. Different sampling frequencies correspond to different magnitudes of angles of the individual rotation steps. We can observe that the error increases with the magnitude of the individual rotation angles. For large angles, angular orientation becomes completely unreliable.
