Hi Martin, No there was also a SDR hack to spoof. http://www.rtl-sdr.com/cheating-at-pokemon-go-with-a-hackrf-and-gps-spoofing/ --      Björn Sent from my smartphone. -------- Original message --------From: Martin Burnicki <martin.burnicki@burnicki.net> Date: 14/08/2017 11:42 (GMT+01:00) To: Discussion of precise time and frequency measurement <time-nuts@febo.com> Subject: Re: [time-nuts] Ships fooled in GPS spoofing attack suggest Russian   cyberweapon Clint Jay wrote: > Absolutely, their use of it was for something trivial and my reason for > using that example was to show how 'simple' and available the technology is > if a couple of students could do it with lab equipment that anyone can buy > (obviously you'd need deep pockets). I just searched for "Pokémon GO GPS spoofing" on the 'net. Looks like this was just a hack in Android where apps were provided with a spoofed position from the hack instead of the true position determined by the GPS/GNSS receiver. So this is quite a different thing than spoofing the real GPS signals, and it only affects the devices which have that hack installed. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

But of course it's a nice way to demonstrate how easy it's possible. Thanks for the pointer. Martin
