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."

I used to do this stuff

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.
