GPS Trackers Find Novel Applications
Pickens writes "Inexpensive GPS devices like the Zoombak (which costs just $200 plus $10 a month) have becomes so prevalent that some people are using them routinely to keep tabs on their most precious possessions. Kathy Besa has a Zoombak attached to the collar of her 5-year-old beagle, Buddy. If Buddy wanders more than 20 feet from the house, she gets a text message on her phone that says, 'Buddy has left the premises.' The small size made possible by chip advances over the last two or three years is enabling many novel uses of GPS tracking. An art collector in New York uses one when he transports million-dollar pieces, a home builder is putting them on expensive appliances to track them if they disappear from construction sites, a drug company is using them after millions of dollars in inventory turned up missing, and a mobile phone company is hiding them in some cellphone boxes to catch thieves."
Ok, say I'm paranoid. Is there anything on the market that can detect these devices?
Give me Classic Slashdot or give me death!
$200 + $120/year? Not "inexpensive" enough for me to stick onto my dog!
... no potential for abuse whatsoever!
I caught the Mountain Wumpus! He gave me his treasure chest ($100) to let him go free again.
An RFID tag can't be used to track something very far from the RFID tag reader, let alone globally.

How come there is no first post? I'm confused.
Mahalik: She told me that she heard a zombie going through her trash the other day. The next morning, she turned up missing.
C. J.: What? Okay, back up. How in the hell do you "turn up missing"?
Mahalik: 'Cause nobody knows where you are when they realize you ain't there!
C. J.: So you telling me that you can appear and disappear at the same time.
Mahalik: No, man. You can't appear and disappear at the same time. The bitch ain't David Copperfield!
C. J.: Mmm. No, no. But you can't be gone from one place and show up somewhere else entirely. So when you turn up, you're never missing. And when you're missing, you never turn up.
Mahalik: Unless... you a zombie.
C. J.: Damn! Hey, that's some plausible shit right there. You should blog about that.
Mahalik: I'm gonna put that on MySpace.
C. J.: You do that!

I work for what's left of a company that actually managed to go bust developing this stuff.
We faced several challenges with the technology. Power consumption gave us ulcers, as did mobile network coverage. This is a non-issue in the city, but just wait until you're out of town.
GPS wanders around enough from fix to fix, even with WAAS, that it can be tricky to compare fixes to detect movement, or to track movement of less than 50 meters. Oh, and the GPS needs to be able to hear satellite signals. Good luck on that.
Finally, once you have a fix back at your server, you need to make it meaningful to the user. They do not generally want a bare latitude and longitude. They want to know what street their car is on. When the parents want to know if the kids take the car too far from home, they want to enter a street address, not a latitude and longitude. This is harder to get right than it looks.
Favourite application: tracking sub-prime used cars so repo men can find them.

It's funny how the Times' editors felt it necessary to punctuate each letter in "G.P.S.". What is this, the Man from U.N.C.L.E.? Maybe some year they'll realize that GPS is regular everyday stuff. You know, like A.T.M. machines and D.V.D. players.
I've been wondering how long this would take to get into a more public role. I've had ham radio based APRS (http://en.wikipedia.org/wiki/Automatic_Position_Reporting_System) installed in my cars for a while. When I show people a publicly available map of my travels, reaction ranges from salivating impressed (it's probably been ham radio's last "killer app"), to absolute horror ("you mean, you don't care if people know where you are?").
But, I think a lot of people would willingly turn on such a feature (say, on a mobile phone with a GPS chip and a GPRS connection.
Anyway, I read the article to our beagle and asked her opinion. She points out that beagles do not run away, they are called away on urgent tracking business. She feels that any human that hangs out with beagles and wants to attach tracking boxes to them is a distrustful person who possibly lacks the right spiritual qualities. She also reminds me that she can detect a beagle treat coming out of the bag across three fields, and that in any case anyone who has trouble with beagles taking off is simply not taking them for sufficiently long walks. She thinks I should notify the ASPCA before relations completely break down between this unfortunate beagle and its lazy, distrustful owner.
From scarped cliff or quarried stone she cries "A thousand types are gone, I care for nothing, no not one."
actually, the nursing home my grandma lives in uses this sort of thing for their advanced alzheimer's patients. they implemented it after one of them wandered out last winter and died from exposure.
upon the advice of my lawyer, i have no sig at this time
The advantage of using dumb old radios is that you can operate independent of any fixed infrastructure, so it's usable even where you don't have cell coverage.
Tracking something small like a dog (I've had inquiries about kangaroos, too) introduces the problem of antenna placement, though. APRS is typically used on the 2-meter band, which means a quarter-wave vertical antenna is half a meter long. I did once put a passive data logger on my cat, and found that she roams a little more widely than I thought, but that doesn't really count.
The advantage of relatively low frequencies and high transmit power is that you can cover a radius of 20 miles from one mountaintop digipeater (equivalent to a cell site), and they're not difficult to make solar powered.
There's a nationwide digipeater network in the US, and most of Europe is covered as well, along with much of New Zealand, Australia, and many other countries. I think there are at least two APRS-capable satellites on orbit too, though PCSAT-1 is dying. Internet gateways are all over the place, so you can map APRS stations online, and not have to maintain any receive-side hardware of your own.
I'm constantly surprised by the applications people come up with for this stuff. The most recent I heard was someone with a cable TV company who found that he could drive around and transmit at low power every couple of seconds and use a receiver back at the headend to plot ingress leaks in the cable system.
Add to that the fact that you can do two-way text messaging, weather, and telemetry, and it's more than worth the hassle of taking a simple multiple-choice license exam. It's this sort of thing that's going to save ham radio (if anything can) - talking to people around the world just doesn't interest people as much these days, when it's so easy to do on the Internet or the phone.
Yes, mobile phones (some of them) have GPS. Yes, mobile phones have unique ID numbers. What you are missing is that "mobile phones" are not the same as "mobile phones in boxes" - as the former (generally) have their battery charged and installed and are powered up, while the latter are inert and those fancy functions don't work.
Using the phones built in features allows you to catch a single end user - once the phone has trickled from thief to fence to dealer to end user. Using a GPS bug you can track the phone through the entire chain and catch the guys at the start of the chain rather than catching the guys at the end and working up. From a LEO and a Loss Prevention point of view, this is much more efficient and effective.
It's called LoJack and I have it installed in both of my cars. You get a break on your insurance and in the even the vehicle is stolen and not recovered within 30 days you get a refund of the purchase price. However, they have a very good track record of recoveries, usually within a couple hours. I talked with two police officers before buying it and they both said it was great to have. Only works if the police closest to your car have the equipment but it's become standard with most cop shops so that shouldn't be a problem.
They also have an early warning system which I have on one of my cars and it's more annoying than anything. Basically if your car moves without the little box you keep on your key chain being present within the vehicle, you get a phone call / email / or text message (your choice) alerting you. The only problem is you have to change the battery every couple of months or you get false positives.
After having my neighbors truck stolen from right next to my open bedroom window one night, I decided I wanted something more than just a normal alarm (he had an alarm, his truck was locked, we never heard a thing and he never got his truck back) so I went with LoJack.
How is it that one careless match can start a forest fire, but it takes a whole box to start a campfire?
Additionally, one of the studies mentioned in Freakonomics was that having LoJack in just some of the cars in a city made cars less likely to get stolen, as you don't know if you are stealing the one with LoJack or not - and car theft rates for the whole city went down. Something like a network effect.
My GPS Tracker sent me this, about Buddy:
"Buddy has left the preferences"
"Buddy is in the neighbor's trash"
"Buddy is running into the street"
"Buddy is in the same position as a Chevy Suburban"
"Buddy is stopped on the street"
"A google satellite photo is attached with a picture of Buddy"
"Google Adwords has selected "Shovel" as something that you might need with Buddy."
This is my sig.
