I can't speak for all GPS devices, but many are passive and do not actually emit a signal.

As I understand it, the satellites emit a periodic signal with location and it is then triangulated.

I could be wrong though,

Good Morning,
The replicant website says that for the galaxy s2, the gps do not work.
I guess because there is no driver. But does the gps still emit
électromagnetics fields anyway ?
Same question if i do not install the firmwares for wifi and bluetooth.
If i put the phone in airplane mode there will be really no more
electromagnetics fields ?
This is because i don't like too much the electromagnetics fields, i
like to put it in airplane mode
Thank for your answer.
