<p>This paper addresses both the efficiency and the portability of a computer program in charge of the baseband signal processing<br>
of a GNSS receiver. Efficiency, in this context, refers to optimizing the speed and memory requirements of the software receiver. Specifically, the interest is focused on how fast the software receiver can process the incoming stream of raw signal samples and, in particular, if signal processing up to the position fix can be executed in real-time (and how many channels the host computer executing the receiver application can sustain in parallel). This is achieved by applying the concept of parallelization at different abstraction levels. The paper describes strategies based on task, data and instructionlevel parallelism, as well as actual implementations released under an open source license and the results obtained with different commercially available computing platforms. At the same time, the proposed solution also addresses portability, understood as the usability of the same software in different computing environments.</p>
