This android application is the product of attempts to solve an open research problem i.e. Indoor Localization with using GPS on Mobile devices. This can also be viewed as a measure to save enery on the device by not polling the GPS sensor as frequently as it would have been under normal circumstances. It uses Pedestrian dead reckoning algorithm to calculate the relative position of the device from the latest known GPS fix.
Sensors used: GPS, ACCELEROMETER, MAGNETIC FIELD
Recommended position of device during movement: The device needs to be held in as the user walks while moving his hand naturally. The top edge of the device must point in the direction of motion.
