Tracking Location in the Absence of GPS Using Smart Phones

The objective of this paper is to review existing research done on mobile phone based dead reckoning and to integrate algorithms from various existing research together in a single algorithm incorporating step detection, orientation detection, step length calculation, which gives a good estimated location even in the absence of GPS, provided the initial GPS data is available. In this paper, they have explored implementing a dead reckoning system based upon using an accelerometer as a step detector and a compass as a direction detector.
