Intentional GPS Jamming On the Increase

benst writes "Here's yet another way to measure the success of GPS: by the efforts to negate it. While unintentional jamming continues to rise, intentional jamming by both foreign military forces and at-home miscreants of various stripes has shown increased vigor in the past six months. Related here are recent instances of intentional jamming on each side of the border, and (briefly outlined) one initiative mounted by the National Geospatial Intelligence Agency (NGA) to counteract it. Also, here are some ways to detect and prevent jamming."

Because GPS frequencies are a secret, and RSA encoded.

How could they be jamming us if they don't know... that we're coming... Break off the attack, the shield is still up.

Shooting down a U.S. military satellite doesn't sound like a particularly well-thought out plan to me.

I don't understand why people bother with GPS I had one but their is very little point in them for road use.

Anyone with the capacity to down multiple satellites (losing one wouldn't do much) 20,200 kilometers above the surface of the Earth is not going to be posting about it on slashdot.

LOL!

That is such a great, simple, and elegant solution. You fail to mention that the sign would be placed a couple hundred feet away from the entrance to the bridge/tunnel, but I assume you meant to say that.

However, this is probably too intelligent to be implemented anywhere. You're too smart to work for government buddy. Sorry :)

If your driving examiner tells you to mow the old lady down or speed up to 80 in a 30 area, you wouldn't do it

Clearly you didn't get your license in Spain, where some people spend up to 3500e ($5514.95). Where each fail after the first four can cost you 1500e. Where some people offer money, sexual favors, etc to the examiners.

If the examiner tells you to mow down a lady, you ask "HOW HIGH!".

True Story - Some years back at the Telco Supplier that I worked for we had one of those Corporate awayday things at a Hotel in Bristol - We were all instructed to use the Multi-storey car park nearby. When I drove the 4x4 I had at the time into the car park I noticed one of those hanging signs notifying low headroom and drove slowly under it, relieved not to hear any scrapes..

Later, during the presentations from the PHB's, one of them confessed that he and another PHB had arrived in his new BMW X5 and when they saw the same sign he asked his passenger to get out and make sure they could pass beneath it safely.. He started edging forward as the passenger called out 'Ok, Ok, keep it coming etc.' And then they were through but he was quite disconcerted at how close the ceiling seemed to be as they drove up through the car park and he commented on this to the passenger and asked how much clearance there had been between the car roof and the hanging sign. The reply was something like "Oh none, so I just held the sign up a couple of inches.."

I think he was the Technical Services Manager...

Or welsh ones, even if you speak the language the place names will take you so long to read youll already be through the village before you work out what it means.

After all, they deny lots of junk up there.

Just shoot one of them down and see who complains and THEN you'll know whose it was.

If this gets used as a strategic attack by religious extremists, they would be "jammin' in the name of the Lord".

You'd think so, wouldn't you?

[supercrisp]

I used to work in a an office in the English-Philosophy Building at the University of Iowa. The street in front of our window, Iowa Avenue, had a low bridge accompanied by a warning side about a 100 feet away with chains that dangled down to hit the roof or window of vehicles too tall to make it under the bridge. I'd say about twice a summer, when all the students were moving, moving trucks would ignore the horrible crash of the chains to next produce the extremely loud boom of a truck smashing off the first three to ten feet of the cargo box. Sometimes commercial trucks hit it too, but moving time was the real season to see this. I think I saw one truck in my whole eight years or so there that actually backed up and went around. Of course, I probably missed quite a few doing that, as what really made you take notice was the collision with the bridge.

Interesting..... sexual favors you say?

Is it a requirement to speak Spanish to be an examiner in Spain? Would pig-latin pass?

I think this is a job I could do.

My dad likes to tell the story (over and over again, as all old men do) of the time he saw a fire chief's suburban pull into a parking garage. The roof and lights were low enough, but the big whip antennas weren't. When he passed under a low beam, the antennas were pushed back, and then, when he cleared the beam, they whipped around in a circular fashion and broke every single light on the roof. I wish I could have seen it.

I'm hoping that "was" is the key word here.

If your bridge is 8 feet high, you simply need a metal arch 9 feet high, and a 'low bridge' sign suspended from it by two one-foot pieces of chain.

(It's called a "tell-tale").

I've seen better. In Toronto, underpasses have a photocell (and light source) setup 200 feet from it, and a flashing light "too high truck" is fitted on the underpass. The flasher kicks-in whenever the light beam is interrupted.

And, yes, kids *DO* take a plank and cut the light beam whenever a truck goes by...

I've been using mine for GPS-assisted hypermiling (i.e. take your foot off the gas when the display says you're 0.4 miles away from the next stop sign or intersection. I can eek out another 5-7 mpg doing this ....

Thank you asshole for slowing everyone else down! Now get out of my way before I run you over with my Hummer.

Would you miss it?

With my unsteady rifle hand? Most likely.
