[Starlink] Starlink cheaper in Colombia,cand gps spoofing

[Mike Puchol]

I can confirm that spoofing with “non-milspec” methods don’t seem to work against the receiver in the Starlink terminal. I tried with a HackRF and a USRP and it didn’t work, while an Android phone was spoofed fine. I was however able to jam the receiver with very moderate power levels and a sweep generated with a HackRF Portapack and patch antenna.

Best,

Mike
