I doubt it works. More likely a cell phone harvest of some type.

Maybe it works someplace, but not in the US in general.

Current rules (for the nitpickers: simplified, add detail as you desire)
say the GPS tracking stuff in the cell phone is only enabled in an
emergency, e.g. a 911 call, or if you have signed up with the carrier
for such service for personal reasons such as tracking your kids.

We've used cell phone tracking for SAR in CAP. However, you have to
work directly with the cell phone provider, it doesn't appear that
there is any software that simply says "you are here", its an engineer
looking over stuff giving you his opinion. Even at that, the possible
range was pretty large as I recall.

That was probably by cell site triangulation, which gives you a big
area and one of the reasons why the Feds are pushing E911.

With the new phones with built in GPS (which eventually are supposed
to replace all existing cell phones) the accuracy is, well, GPS
accuracy.

If anyone wants all the gory details about GPS in cell phones, you
can go tohttp://www.fcc.govand search for E911.

Mobile phone tracking is available as a commercial service
in the UK using the 'triangulation' method.

"We have seen mobile phone accuracy as precise as 100m in central
London (where there are many cell masts) and as inaccurate as 10km in
the Scottish Highlands(where there are few cell masts)."
