DDK Nav is a simple and effective application that enhances the accuracy of the GPS measurements from your mobile phone. The application initially uses the mobile phones GPS measurement, and then removes the majority of the errors that are contained in each position fix. This will result in up to 70% increase in your position accuracy.
