Abstract

The software defined radio (SDR) global navigation satellite system decoder gnss-sdr, based on GNU Radio, is used to prototype computationally efficient global positioning system (GPS) anti-spoofing and anti-jamming strategies using controlled radiation pattern antenna and null steering towards a unique interfering source. Experimental demonstration is achieved on GPS L1 when running gnss-sdr on a Raspberry Pi4 single board computer fetching radiofrequency datastreams from an Ettus Research B210 SDR frontend.
