How does a YS1 specifically receives only the real signal and not the jammer? As far as i know, a YS1 aint a real SDR, so you cannot use gnuradio to put a filter on top of the jammer. It applies the baseband filter moved up to the intermediate frequency , then it performs decimation by a factor and a de-rotation with to downshift the signal to baseband. GNURadio makes it easy to filter out the jamming signal and obtain the authorized remote signal. These SDRs are able to use GNU Radio software, SDR# software or other SDR software for configuration and control of these devices. Setting the receive frequency of the YS1 ontop of the real signal is enough so it only hears this signal? I am a bit confused about this. Assistant professor of electrical and computer engineering at Virginia Tech Brent Ledvina explains how GPS spoofing works, “It’s almost like someone nearby is spoofing your favorite radio station by transmitting at the same frequency but higher power, fooling your receiver into believing it is getting the right station.
