i had not seen the trick of squaring the GPS signal to get rid of the
phase modulation and hence the spread spectrum to only recover the doppler
shift elsewhere: looks like a great trick to validate the reception of a GPS
signal even below thermal noise levels.
What is the difference between the receiver tech in something like a CSR
chip vs USRP?

Yep, brute forced it should be possible :-) Not really the same like with
UMTS or LTE...
