Benefits of a multi-GNSS receiver in an interference environment

In this paper, we investigate the benefits of a MULTI-GNSS receiver in an interference environment. The global satellite navigation systems GPS, GALILEO, GLONASS and COMPASS will be considered. The regional navigation systems QZSS and IRNSS are not part of the investigation. We assume that a future Multi-GNSS receiver will use only CDMA signals. Therefore, the FDMA signals of the GLONASS system are not included in the simulations. Precise almanac data are used to simulate the satellite constellations of the GNSS systems. The link budget for the received signal power includes all major path losses and antenna gain factors. Finally, the results of the interference calculations are presented for the Earth surface.
