Can a GPS device be tracked like a cell phone can?
It’s well known that cell phones can be tracked because they have transponders in them. Can GPS devices also be tracked (not GPS phones but standard small GPS devices like the FastFind 210)?

Correction: I referred to the FastFind 210 which is a Personal Locator Beacon. With these units you want to be located! These may have a GPS unit installed to help with location.
I meant to refer to true GPS portable units like Garmin’s eTrex and GPSMAP.
Addition: I want to know when GPS units are on can they be tracked in any way: can their signals be tracked by any satellite, plane, military or police.
To be tracked, you need a connection to a network, where you can send your data.
It can be wi-fi or mobile wireless or even RF.
No network or transmitter – no tracking.
