Caption: FIGURE 4: The sample mean of the gyro drift.
The step length model needs to be adjusted to each user as the model parameters are dependent on the pedestrian's physiological features and gait cycle, whereas headings are potentially misaligned with the actual walking direction because of gyro drift and the device carrying mode.
The initial gyro drift rate is 5 deg/h and the standard covariance of the driven noise is 0.003 deg/ [square root of h].
It is obvious from Figure 7 that on the no-faults condition the gyro drifts and position information can be well estimated, especially since the estimation error for east gyro drift is less than 10%.
