Abstract:	This paper describes a recent update of the PC-based real-time software receiver SX-NSR to process L2-P signals via cross-correlation tracking and the Galileo AltBOC signal via split-band processing. The NavPort-4 inter-frontend link allows synchronizing two frontends for up to eight RF chains or for dual antenna usage. The SX-NSR is now able to acquire and track all civil GPS, Galileo and GLONASS signals. Around 20 high-bandwidth channels can be tracked in real-time per x86 CPU core (i.e. 80 channels on a laptop, 240 channels on a high-performance PC). The receiver is running semi-permanently on the observatory Lustbühel/Austria, collocated to the IGS point GRAZ. The data is analyzed with the Bernese Software 5.0 within a local and a regional GPS network confirming its geodetic data quality.
