With the recent launch of the first Galileo test satellite GIOVE-A, Europe made the first really important step towards the so-called global navigation satellite system, which is already represented by the GPS and the GLONASS systems. In this context, the co-operation of these systems from the receiver point of view is going to ask the market for providing a user terminal able to deal with different signals. To achieve this target, a possible way forward goes through the study of dedicated signal processing algorithms based on software radio defined principles. The paper introduces the FPGA+DSP platform developed at the Politecnico di Torino, pointing out the advancements on the architecture design. Some results in terms of signal tracking performance are also presented and discussed
