Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to perform a distance travelled estimate with a mobile device. The distance travelled estimate is performed by determining a quality of displacement between a base position and each new position for the mobile device, which is determined based on the displacement between the positions and their associated uncertainties. If the quality of displacement is sufficient, the distance travelled estimate is updated using the displacement between the positions. Multiple tiers may be used, where, for example, if the quality of displacement is sufficiently high, the displacement associated with a preceding position may be excised from the distance travelled estimate and replaced with the displacement associated with the new position. Additionally, if the quality of displacement is even greater, the new position may be set as the base position.
