The increased use of systems based on satellite navigation (tracking, geo-fencing, fleet optimisation, field marking, augmented reality games, etc.) has also led to the development of devices which may interfere with receivers (jammers) or even be misleading. Popular solutions are based on the programmable radio (SDR), which captures the raw electromagnetic signal in the considered frequency band, converts it into digital form and then sends it to a computer. Although almost all jammers emit chirp and poorly stable signals, whose spectrum is centred around the GPS frequency L1 (1575.42 MHz).
