Ionospheric Effects on Future Navigation Signals: Frequency Hopping Modulation

Noah Francis, Brian Breitsch, Jade Morton, Joanna Hinks

Abstract: The next generation of GNSS promises new satellite constellation and signal designs that will improve capabilities and performances for all users. In particular, novel signal designs are being explored with different characteristic modulations and bandwidths. These range from wideband altBOC signals like Galileo E5a and E5b to other signals of opportunity using communications waveforms. While these are all welcome improvements, one effect that will always persist for any GNSS is the effect of Earth’s ionosphere. This project is aimed at investigating the potential impact of the ionosphere on these new types of satellite navigation constellations and signals. This study focuses on the specific example of frequency hopping modulation (FHM) signals, which have been used for communications and have the potential for interesting ionospheric effects.
