Multicarrier Navigation and Authentication: Control-Engineering and Bio-Inspired Approaches

In light of additional costs associated with existing and proposed mechanisms for authentication above the physical layer, alternative analyses and design frameworks for resilient navigation and authentication at the physical layer where the authentication information is transmitted concurrently with the navigation data need to be developed. This paper presents a few ideas for future Global Navigation Satellite Systems (GNSS) on the subject of superimposing both carefully designed navigation data and authentication tags on low-latency multicarrier GNSS waveforms without requiring additional powers and bandwidths. The state-of-the-art optimal control engineering and biologically inspired techniques are utilized to maintain integrity to uninformed GNSS receivers, robustness to interference, and security for GNSS identity verification.
