Spoofing GPS Coordinates using HackRF One For quite some time now, I have tried my best to show and explain how fantastic RF is and how dangerous it can be…

Spoofed GPS is causing more problems in Europe, thanks to Russia's persistent jamming.

Here, we take a look at how it works in a lab environment.

It's sale time with @OSSDRLab
