Study of Different Methods and Algorithms for Pedestrian Positioning

The primary routing,done by landmarks, celestial objects and magnetic compasses.With Advancements in science and technology today, inertial sensors and advanced satellite systems and ultrasound waves are used for positioning.Navigation systems for the vehicle, is a technology, which today has become more widespread,With the increased small portable technologies,A new group of users, ie pedestrians have been added to the users of navigation systems,Pedestrian navigation is a fascinating subject,So include a wide scope of applications and a large number of potential users.Currently, there is a great deal of research in this area and many commercial products have been developed.Due to the unpredictable movement of people and environments that are somehow involved with them,Quality pedestrian navigation services can not simply be guaranteed everywhere.Certainly for navigation in open environments,Technology is the first satellite positioning systemsbutin enclosed areas or in urban valleys the situation is more complicated and more difficult(Buildings and human infrastructure, satellite signals weaken and are blockages).For solving this problem, methods have been proposed for pedestrian navigationIn this study, have presented new methods of positioning pedestrians, including positioning with wireless waves,Lamps LED (visible light communication), integration of systems, inertial sensors, Map-matching algorithms and Strategies to improve the accuracy of positioning.And accordingly could, chose the most efficient method to suit your needs.
