Tracking Loop Distortion of BDS‐3 B1C Signal in Spoofing Scenarios: An Experimental Analysis
This study established a feeder‐based BDS spoofing experimental platform and uses multi‐correlator tracking to systematically analyse the tracking loop distortion characteristics of BDS‐3 B1C signals under position and time spoofing, comparing differences between narrowband (NB) and wideband (WB) tracking modes.

GNSS Spoofing Detection Based on Ionospheric Model Deviation Monitoring
The deviation of TEC (DTEC) consistency between DF measurements and empirical model estimations in authentic scenarios is not zero but is predictable through ionospheric annual periodicity. However, DF spoofers typically struggle to accurately counterfeit the authentic TEC value, which can disrupt the consistency between DTEC measurements and ...
