GPS Jammers - Vulnerabilities and Spoofing of Satellite Navigation and Timing Systems


In today’s data-driven world, receivers and sensors along with historical data have been used to hunt down willful and intentional GPS jamming by people wishing to evade tolls, trucking companies, employees wanting to evade employer surveillance as well as sophisticated jamming patterns and spoofing that would require a highly-sophisticated adversary and gear that is not available to the average citizen.

This on-demand webinar gives a brief introduction into the vulnerabilities of satellite navigation and timing systems and the ways in which these vulnerabilities can be exploited. The specific vulnerabilities of GPS-based systems are introduced – the main vulnerabilities of GPS are due to the very low signal strength of the satellite signals. The on-demand webinar also discusses the effect of Radio Frequency (RF) interference on satellite navigation and timing systems and uses some real examples of disruption caused by real-interference events. We also highlight that spoofing can be carried out either at the application layer (using PokemonGO as an example to demonstrate this) or at the RF level – where different examples are used to demonstrate this.

About this On-Demand Webinar:

  • Real examples of GPS jamming attacks (deliberate and even accidental)

  • Real examples of GPS spoofing – At application layer, Pokemon GO game

  • Automatic Identification Service (AIS)

  • At RF level – DEFCON examples/demos and the attempted spoofing of drones
