Abstract [en]

This thesis evaluates a hypothesis about how to implement a low cost Differential GPS (DGPS) solution, able to find a current location with a precision almost as good as more expensive DGPS solution.  For this purpose two Smartphone’s are used, one used as a fixed reference station and another used as a roving receiver. The reference station calculates the temporary error at its location at every second and transmits these errors to a server over the internet.  The roving receiver requests to the server to get the latest error from the reference station over the internet. By using these errors or differences, the roving receiver finds a corrected location. The results are in the same range as dedicated DGPS solutions.
