How GPS spoofing works and how to block it?
Hello, Mike! First of all we have to tell you that GPS spoofing is really possible. The main reason for this is the fact that GPS signals are poorly protected and are really weak. That’s the reason why you can loose GPS reception at the parking lot or in densely populated, urban area. The whole thing works the same as GSM cell tower spoofing. As long as the signal is weak, you have to send a fake GPS signal to your victim, that is just a little bit stronger than the original one. That’s how those students from University of Texas were able to do it, but it is good that they’ve had a scientific reason, not criminal. That’s why you should remember that GPS technology may be used by evildoers too. So, they’ve simply made navigation system of that yacht think that it has a non-existing three degrees course collision and the crew have corrected that. That’s how they’ve directed the yacht where they needed it to be, and the crew didn’t even know that they were manipulated. But we at know a couple of ways to block that GPS spoofing. In order to use that vulnerability the fake GPS signal must be stronger than the original one, so we recommend to block GPS signals on the desired areas and switch to GLONASS or another global positioning system. But be careful with GPS jamming device in your naval journeys, because you may block the signal entirely and what’s worse – you may disrupt other ships’ navigation. Thank you for your question, I hope, I’ve managed to help!
