Think GPS Invades Your Privacy? You Ain’t Seen Nothing Yet!
Speed trap? Or something much more insidious? This police officer seems to be striking a pose familiar to many, many drivers. Is he aiming a radar gun at passing traffic looking for the guy going 10 or 15 miles over so he can issue a ticket and meet his monthly quota? (Sorry, made a mistake there, in my city they emphatically have no quotas; they have “Monthly Performance Standards” … makes one feel a lot better about getting a ticket.) But annoying as a traffic ticket may be, there’s an already well-advanced police activity out there today … not next decade … that could be one heck of a lot more troublesome than a couple more points on your license. I’m writing about this today because in my field, GPS tracking technology, invasion of privacy is one of the prime issues on many people’s minds. Folks, especially rabid privacy advocates, you ain’t seen nothing yet.
… In recent years, police around the country have started to use powerful infrared cameras to read plates and catch carjackers and ticket scofflaws. But the technology will soon migrate into the private sector, and morph into a tool for tracking individual motorists’ movements, says former policeman Andy Bucholz, who’s on the board of Virginia-based G2 Tactics, a manufacturer of the technology.
Bucholz, who designed some of the first mobile license plate reading, or LPR, equipment, gave a presentation at the 2006 National Institute of Justice conference here last week laying out a vision of the future in which LPR does everything from helping insurance companies find missing cars to letting retail chains chart customer migrations. It could also let a nosy citizen with enough cash find out if the mayor is having an affair, he says… Rest of Wired News article here:
I thought this was pretty interesting, to say the least. The criticisms of GPS tracking technology center around the fact that it is invasive, may give people a lot of problems for the tiniest lapses that are only human nature, and may divulge information to parties who never were envisioned by the folks who originally set out to collect the data.
Certainly all of these objections have some substance and are worthy of discussion. As a GPS tracking advocate I counter that there are safeguards which can mitigate the issues. In general the court system has pretty much sided with me.
The general rule for law enforcement is that they can use GPS tracking technology, with little or no probable cause, because GPS tracking is, essentially, only an electronic way of replicating a law enforcement officer following a suspect to observe behavior. In most cases, a private citizen would not have the right to place tracking technology on another citizen’s car … although, in general, it’s not illegal to follow and observe another’s activities on public thoroughfares.

I’m really glad to see this report out of Iridium. What has this got to do with GPS you might ask? Actually it’s got two important GPS connections.
But Inmarsat “birds” fly at geostationary altitude … 23,000 plus miles above the equator. It takes radio signals about 400 milliseconds to go “up” to the birds and the same ~400 ms. to come “down”. That’s 800 milliseconds, plus a little time for the on-board processing so it adds up to nearly a full second of delay. You may have used a satellite phone running off geostationary satellites … if you haven’t, you’ve seen those annoying television interviews where the anchor person says something to the correspondent in Iraq and it seems to take forever for her to hear the question and answer back … when you’re looking/listening to a conversation like that on USW television it’s nearly a 2 second delay … and two seconds of delay in an interactive conversation is a problem.
Nobody likes paying the prices we do for gas, but you can turn the tables on your competition if you play your cards right. A year or two ago you could save a hundred or two per month per vehicle … now it’s easy to save more … you’ll be saving, they won’t … something like power play in hockey, isn’t it?
