The question for GPS is somewhat related to GSM, since there is not much use in measuring position of a Gadget with 10 m accuracy when you know it's AP anyway.
But with GSM, this question might be relevant.
Well, and GPS delivers a very precise time signal, which might come handy for some settings.
GPS recievers issue position infromation at a serial line, so, in question of hardware, this should not be difficult.
And I'm quite sure that there are some NMEA-parser for arduino available as well.
My personal use case was about surveillance of an agricultural irrigation system:
The irrigator is at the end of a hose, pulled towards the roller trolley, at about 1cm/second.
I would need both pressure and position of the irrigator at e.g. 1/2 hr intervals.
And of course, pressure at other points as well...
