The project aims at developing a navigation system which helps the pedestrian to locate his/her current position even if the well known technology like GPS used in navigational system fails. The proposed system has a GSM modem to trace the current location. Dead reckoning is a form navigation whereby the current position of pedestrian is deduced by knowing speed and direction of travel since the last known position. The primary advantage of dead reckoning is that it relies on sensors contained within and, therefore, provides a navigation system that requires no interaction with the world outside. A self contained navigator such as this is desirable especially as a backup navigation system. The largest location error of the IPNS prototype is ∼40 m in an urban area with a 2100-m- long distance. The controlling device of the whole system is a Microcontroller. The microcontroller continuously reads data from GPS (Global Positioning System) receiver and displays this information on LCD display unit. When the system is not able to read the data from GPS receiver, it automatically switches to the backup navigational system from the last stored GPS location. This back up navigational system has a Digital compass and Pedometer button which helps in locating the movement direction.Also the heading direction is shown through a LCD display. The pedestrian location can be received by simply sending an SMS to the system.
