Does anyone have a technical explanation of how gps spoofing works?
Here is some slides from Defcon 23 : https://media.defcon.org/DEF%20CON%2023/DEF%20CON%2023%20pre...
They did a record, replay with a USRP B210 and GPS antenna.
And here is a project that generates GPS baseband signal data streams for bladeRF, HackRF, and USRP.
