GPS Spoofing

The Global Positioning System (or GPS) is a satellite navigation system that uses satellites to provide autonomous geo-spatial positioning. This technology is everywhere – it’s in your car, your smartphone, your watch, your fitness tracker, handheld GPS receivers, and more. But did you know that these satellite signals can be jammed – or even worse – deceived using something called GPS spoofing? Let’s take a look at this interesting topic of discussion. What we’re going to review here applies to any of the popular satnav systems – that includes GPS (the US satnav), Galileo GNSS (or Galileo Global Navigation Satellite System – the European version), and Russia’s GLONASS system. How does GPS work? There are multiple GPS satellites in orbit around the earth. Special chips can be included in nearly any electronic device that can read signals transmitted from the satellites. And combined with a bit of math – the device can determine your position with great accuracy as long as it can receive signals from at least 4 of the satellites overhead. Sound expensive? Yep – it is. (At [Read More…]
