GPS trackers - a potential weapon from hell

GPS trackers arent hard to find. Their pitfall is they have to have a reasonably unobstructed view of the sky. So give your car the once-over. If there's a little black box on the roof, trunk, or hood, maybe right now isnt the best time to go visit your "friend" across town.

Why oh why would you have police helicopters circling over your car at regular intervals???

Thanks for replying, but would you care to read EXACTLY before commenting? As mentioned in the summary on the talk page (item 7), the military/LEC version of them seems to be so small and sensitive nowadays that it can be hid practically anywhere at your car - also under it.

I look forward to hearing from you again, after doing the necessary homework.

Would the growing trend towards totalitarianship of our socities be an explanation? Dissidents were fought against through the former Soviet Union, and our 'free' societies are apparently not so different in this respect.

"seems" isnt good enough. It's MIGHTY unlikely a GPS reciever could work from under a vehicle. Receiving the satellites is just BARELY possible when you have them in line of sight. Under a vehicle would be about 50db worse (100,000 times weaker signal). That would put the signal waaay under the background noise level.

Do street lights go off as you approach them, then go back on once you've passed?

I don't want to be unpolite, but if you're serious about it, why don't you just take the 5 or 10 minutes necessary and really read (word for word) the article and chapter 7 of the talk page? Then you should be up to date.

I mentioned it there already, but fearing that you again read over it, let me repeat it here: Leading german maker Fugon has a PW-protected folder called BOS (=3D LEC) on its german version at

Maybe an 'ancient hacker' is not the guy needed to solve the mystery.

That isn't a discussion about GPS trackers, it's a pitiful dissetation about Orwellian fears. The final sentence regarding cell-phone tracing basically admits that current methodology can be easier anyway.

GPS trackers are ideal on truck fleets and shipping containers. It's actually pretty handy to know where a container is once it's fallen overboard. You might mention that, as well as your useless fearful diatribe.

Why don't you just READ and THINK, if you can - the entire talk page, in this case. Then you would also have seen that there was a constitutional court case in Germany about a year ago about the legitimicy of these devices (i e their covert police use). And you're trying to make us believe that they don't exist, and that contenders to the contrary are madman.

My conclusion is: Either you're one yourself, or you belong to the LEC etc who fear to lose a weapon too mighty for them.

An associate of mine told me that he just went to the pound to adopt a cat. It was REQUIRED that the cat be injected with a "tracking" chip (RFID, not GPS).

Not at all, last generation commercial GPS have outstanding sensitivities (-158 dBm and more) and work even indoor.

The right countermeasure is a strong beacon on the GPS frequencies.

Jim Thompson wrote in news: snipped-for-privacy@4ax.com:

Well,that is not truly a "tracking" chip,it's more of an identity card,and must be scanned at short range.It can't be used to locate a lost pet(DF),just to identify an unknown pet.Because collars with ID tags can be removed or otherwise lost.

It's not for tracking per se, it's for identifying. Partially to identify the cat, partially to identify you as the owner.

Yeah, the EM-406 and EM-301 from USGlobalSat have sensitivities of -159 dBm. Quite good too and works indoors - as long as you can see a window (and even then, barely).

I've worked with real GPS devices and trust me it's not easy to get a constant fix if you have terrain around you. Even skyscrapers would block GPS signal. The patch of sky directly above you is sometimes not enough to give you a position fix since there is always the possibility that there are no GPS sattelites there at the very moment you decide to take a reading. GPS devices work best if it has a 360 degree view of the sky.

Though to be fair, for 'tracking' purposes you don't need a constant fix. You just need to get your position once in a while. So erratic performance is acceptable. The most important position you want is probably the final destination. But again, the GPS tracker fails if the target decides to park in a basement.

You realize the GPS signal is already well beneath the background noise level... right?

This is a good way to forefit a very large chunk of change or spend a lot of time in jail if you're caught; there's enough commercial usage of GPS signals these days that there's plenty of money to go after anyone jamming them.

You might as well jam your local cell phone towers while you're at it too -- see how long it takes Sprint, Verizon, etc. to track you down! :-)

That is a long way from operating under a vehicle where all you would get is random reflections from metal objects around you. Most roofs are not metal, and even if it is a metal roof, they are not bonded at the seams to prevent RF leakage.
