Design and test of a precise mobile GPS tracker

In the last years the widespread diffusion of smartphones with sensing capabilities paved the way to smart pervasive applications. The tracking of users activities aided by the set of sensor installed on board of smartphones represents a really interesting market for users which today demand reliable, smart and tailored services. The target group of sportsmen was of particular concern in this study. We aim at offering them a tool to record their training sessions along with a web community to share their activities with similar users. To achieve this we have to deal with different issues concerning localization and modelling of the training session by using the GPS, as well as synchronization with the web service to upload the training data. © 2013 IEEE.
