Abstract
Techniques may include ranging between a mobile device and a ranging device to obtain ranging measurements. In addition, the techniques may include performing inertial measurements, where the inertial measurements include directional measurements of movement of the mobile device. One or more of the ranging measurements or inertial measurements may be used to identify dwell points where the mobile device is stationary. Moreover, the techniques may include determining vectors of movement between the dwell points using inertial measurements. Also, the techniques may include determining a first and second distance from the ranging device by performing a first and second ranging measurement with the ranging device. Further, the techniques may include determining a direction of movement using inertial measurements. The techniques may include determining the mobile device is at the second dwell point by matching the first direction of movement to a vector of movement between the dwell points.
