How are these devices legal to sell? (At least in the US, I'm not sure if they even ARE legal.) I am having trouble thinking of a single legal/legitimate use for them.
Jamming is particulalry hard to tackle, since the wireless medium is open to anyone with a trasmitter. So a powerfull enough transmitter can actually raise the noise floor to the level that any usefull signal is not intercepted by conventional receivers. You can use frequency hopping, provided that not all frequencies you use are jammed.
I do think that the security of it should be enhanced.....although it seems to me that standalone GPS devices are outliving their usefulness, anyway....
"I've heard/read about too many criminals who work for the joy of exploiting loopholes. I wouldn't be surprised if someone does a high-tech heist using this one. It'll probably sound too inviting for them, especially considering the cost of these jammers."
I think jamming GPS can be really dangerous. It could easily be used to disrupt tracking on purpose. It would also be very difficult to trace where the jammer is in place.
I don't think a true alternate to GPS exists at the moment. The technology is almost widespread everywhere. Perhaps an alternate can be the use of GPRS based tracking or A-GPS as it's commonly known.
There was an episode of Monk, a USA network show based upon a hacked GPS, which led a rich executive astray where he was ulitmately the victim of a crime.
This was set nearly a decade ago prior to the prevalence of modern day GPS devices which are rather ubiquitous in their availability and affordability.
I agree that we are at risk if the GPS fails.
While on a recent trip through a fairly familiar area, we were being directed via GPS to turn off on perpendicular road, even though it was a gravel road.
We found that there is a battery of settings that were set to avoid toll roads, highways, and several other common topographical features.
We played with these settings eventually, and hacked our GPS into submission! It then let us drive on the main highway to take us to our destination.
If someone were to hack the grid, we could be dealing with epic tragedy, especially where airline traffic was concerned.
GPS jamming is a frightening concept that I'll add to my other technology concerns; like cell phone jamming and RFID interception. What are some of the solutions to these problems? Advanced spread-spectrum with some sort of signal encapsulation (i.e. encryption)?

Businesses often struggle to decide which domain to use. When it comes to purchasing a domain name, you have plenty of extensions to choose from, ranging from .com and .net, to .me, and even .mobi. But which one should you pick?
I've been writing about how the next evolution of the Internet might just be an advertising revolution, and how corporate IT can stay involved as the enablers and providers of the technologies that make this possible.
In the 1970 science fiction thriller Colossus: The Forbin Project, two giant supercomputers from the United States and Soviet Union secretly join forces to take control of the collective nuclear might of the two countries. In the film, the two machines discover each other's existence, communicate back-and-forth, share their collective data, and cut their human creators out of the process. It is the ultimate example of machine-to-machine communications, or M2M.
New York's Metropolitan Transit Authority is conducting a pilot test of digital kiosks to guide subway users to where they want to go more efficiently and at lower cost.
The whole Amazon.reader debate is a double-stupid. It's stupid to think that there's any e-book buyer who doesn't know Amazon's URL, and it was stupider to let ICANN launch the whole free-form TLD initiative to start with.
While NFC's original goal was to enhance mobile commerce applications, it is finding its way into a number of other uses, which is creating both opportunity as well as challenges for IT departments.
Enterprises would like to move to cloud computing but are hesitant because they are concerned about providers’ ability to secure company data. Here are some tips that help to ensure that if breaches occur, the business is not left holding the bag.
Edmunds separates customers into segments based on the info it collects on its site and from partners, and uses that to push out custom content, said Brian Baron, director of business analytics for Edmunds.com, at Predictive Analytics Innovation Summit.
