In dead reckoning, an object can approximately determine its current position by knowing the past position and the velocity with which it moves. Dead reckoning is a navigation technology that needs to begin with a known position; and will then add and track changes. With the right number of absolute position updates, dead reckoning’s linearly growing position error might be contained with pre-defined bound. In order to improve the accuracy and reduce error, dead reckoning must use other methods to adjust the position of the object after each interval. (Alarifi, et al.)
