In Proceedings of International Conference on Indoor Positioning and Indoor Navigation (IPIN 2010). Improving RFID based indoor positioning accuracy using Gaussian processes. Pedestrian Dead Reckoning can provide motion information at a high update rate and achieve high precision over a short time duration, However, without external aids, the system suffers from local anomalies and cumulative error after positioning for a longer length of time.Many researchers use a step length model combined with direction information to calculate the displacement of indoor pedestrians with accuracy step counting method.
