SNAP: A Xona Space Systems and GPS Software-Defined Receiver.

This paper proposes the Satellite Navigation Applied Processor (SNAP), a Software Defined Receiver (SDR) for the Xona Space Systems Pulsar constellation and legacy Global Navigation Satellite Systems (GNSS). The novelty of this paper is found in the creation of an SDR that serves to explore the capabilities of a new Low Earth Orbit (LEO) satellite navigation constellation. The modularity of SNAP allows both industry professionals and students to investigate their own Pulsar and legacy GNSS signal processing techniques.
