Interesting. As far as I know, GPS units suitable for tracking must
be able to transmit a radio signal to a satellite or other receiver.
The normal GPS unit from Garmin or Magellin cannot do so. And those
that can cost lotsa $$$$!

Tractor trailers, shipping boxes and the like have been using units
like this for years. It's also what LoJack and OnStar use. The unit
is a GPS receiver that sends it position either through cell phone or
like on the tractor trailers may even use satellite technology to
report it's position.
Start losing 10 or 15K bucks in appliances and the cost factor goes
way down on a GPS tracking unit.

Also, when I was driving TT in 1999, Qualcomm was using truck tracking
and 2 way communications via satellite. Their system was a couple of
years old then. They also had units installed in the trailers to keep
track of them separately from the truck. The systems cost about 3k
per vehicle then. And that included 2 way messaging.
I'm sure that the costs have come way down on these units now.
Especially since the built in cell phone technology has come a long
way.

Could be Dean, I don't know but they were able to track these appliances
down and arrest five people responsible for these thefts. From what I
understand these thefts had been going on for some time so it was probably
worth whatever the cost to recover these items and prevent further losses.

Oh, I am not saying it can't be done and I suspect they are using a
similar system to truckers positioning. I just don't want people
thinking you can go out and get a handheld Garmin and it will allow
people to track you. That is the argument I had with Mike Gallagher.
He grudgingly admitted I was right.

Not really the LowJack system uses GPS connected to a low power beacon that
can be picked up and located by simple RDF (radio direction finder)
technology that was used in WWII. Some of the tracking devices can read the
GPS location transmitted with the RDF beacon
In the mid '70s someone modified a downed aircraft locator beacon to track
equipment thefts from the I10 long bridge between Baton Rouge and Lafayette
LA.

Sorry Guys,
But, when I did have anything to do with Lojack, all it really had was a
thing best described as a pager transponder. It had no capability to
know and transmit its location. All it actually did was listen for its
number to be called then respond by sending out a radio pulse that
contains its identifier. Its up to the LEO with Lojack provided RDF
units to find our where he is..(thas why every community has at least
one car with four little antennas (antennea?) on top.
