Implementation of a complete GPS receiver using simulink

During the past few years a lot of efforts have been exerted to make the inner working of the GPS receiver visible, clear and easy to learn and modify either on the level of software or hardware. This article adds a step on the route toward the implementation of a more visible, clearer, and easier to learn and modify a single frequency GPS receiver using the C/A code on the L1 carrier. Simulink was used in the implementation of such receiver, thereby introducing a new look for the SDR technology that can be accomplished via a graphical user interface environment.
