Nowadays satellite based positioning systems have become a great part of our lives. Besides the well-known military and defensive applications, they are also becoming more and more relevant for average users and their possibilites are endless. Sports, navigation, and many other aspects of life are in severe need of an accurate positioning technology. Precision must be as high as it can be. While theoratically the positional accuracy of an airborne vehicle does not need to be more precise than a few yards, if one goes for a run in the woods, they might need a more exact representation of their path.

This thesis provides the reader with a brief specification of GPS technology including its foundations, problems, and motivation for further imporovement. Furthermore it also discusses iTrack, the framework created by iData Ltd. New techonologies are discussed from both a hardware and a software oriented perspective. Details are given about the software I created and about the ways in which the original idea changed during development.

Results of data collection are shown on diagrams and explained in detail. The last chapter discusses the possibilites for further research.
