Abstract
A computer-implemented navigation method for implementation during a navigation routine for directing a user is provided. The navigation method comprises generating a navigation route. GPS signals are received and position fixes are derived from the GPS signals. The position fixes are stored and compared with the navigation route. A threshold value is determined based on the comparison of the position fixes with the navigation route. An updated navigation route is generated based on the plurality of position fixes distanced from the navigation route a distance greater than the threshold value and an updated navigation route is not generating based on the plurality of position fixes distanced from the navigation route a distance not greater than the threshold value. A mobile device for performing a navigation procedure is also provided.
