Development of Software GPS+ Receiver Testbed

In recent years many algorithms and implementations have been proposed for software GPS receivers. A software defined radio provides a flexible architecture that allows the receiver to be reconfigured to implement different processing scenarios for different operational environments. Most of the suggested receivers have pre-assigned set of algorithms performing receiver tasks limiting their attractiveness for the research community. This is because many receiver tasks can be implemented using different algorithms and we develop a receiver testbed allowing users to include and/or select different algorithmic options, and test their comparative performances. Such an approach allows more optimal algorithm selection for different computational platforms and simplifies their study. Thus the main goal of this effort is to develop a research platform for testing various algorithms rather than to suggest a specific software receiver solution.
