[PW] GPS

[swguardian-wombat at yahoo.com]

In this day and age, covert spying devices are available to anyone willing to pay for them 
  and using them for stalking and other crimes is a very real scenario.
   
  There are counter measures for discovering GPS and other tracking devices, but GPS 
  is not the only spy/tracking technology that one needs to be protected from. One 
  quality anti-spy device is the BugTrackerPro SG-BTP22 which can expose numerous 
  types of device detection. GPS vehicle tracking devices, room bugs, telephone taps, 
  concealed video Cameras and the "Infinity Device"

  A bit pricey, but if you have reason to be concerned about such things, it can bring 
  piece of mind.

  Since GPS devices are sometimes hidden and used to
stalk victims, what would it require to detect a
hidden one?

I think this depends on whether you're talking about
GPS or A-GPS.
Here's a quick overview of A-GPS:
http://www.globallocate.com/A-GPS/A-GPS_Frameset.htm

and of course, Wikipedia has an entry, with an
explanation of how the
system works: http://en.wikipedia.org/wiki/A-GPS

A-GPS is basically a bare bones locator that really
never turns "off"
unless the phone is off or the battery is dead, I
think, although
some handsets (like feature-rich smartphones and PDAs)
will allow you
to choose whether you want to turn the locator off and
go to
"emergency only" mode. 

A-GPS also works without the use of a SIM card; the US
uses both GSM
(like AT&T and T-Mobile) and CDMA (like Verizon and
Sprint) networks.
