“The US government has been worried about GPS spoofing since at least 2003, when it published seven possible counter-measures against such attacks. “We’re fairly certain we could spoof all of these, and that’s the value of our work,” said one of the Cornell researchers.”

Its nice to see they are using their talents for such a good cause. Tearing down anything thats good seems to be a religion for these kinda freaks.

The military has little to worry about from this, at least. They are many years ahead of Cornell. This was a consideration when the GPS system was created in the first place. The military has ways to spot spoofing.

“Old fashioned Map and Compass.”

You got that right.

Private pilot here, and GPS is a nice luxury, but not a necessity if you know the basics.

But I know it is becoming a necessity very quickly for many.

I am sure military needs are another story all together.

During the war, the Iraqi's tried to jam the GPS signals, rendering the sat-guided bombs inaccurate and useless. The Air Force just grinned and set their toys to home on the jammers.

I knew there had to be a reason why I drove my car into the lake and then over the side of a hill the other day.

Ways to spot spoofing and I’d wager much more advanced ways to trick any enemy who is trying to leech onto our GPS network and use it to his own advantage, or spoof any other system of GPS satellites put up by future enemies. I foresee a day when the next fugitive Saddam Hussein, trying desperately to blend in, drives his beat up old jalopy right up to the SpecOps team lying in wait to kill him.

Me too. As Dan'l Boone once said: "Been a might confused a time or two, but I've never been lost."

1. Military GPS is encripted, so spoofings not a problem. Jamming is an idea, but see #2 .

2. GPS signals are line of sight only, which isn’t a problem for satellites but is a problem for ground based transmitters.

3. Because GPS is LOS, GPS antennas are on top of things, complicating the issue with #2, esp. in airplanes.

4. Things that constantly transmit make wonderful targets.

5. Military applications have other backups, such as laser-ring gyro inertial navigation units.

The military GPS receivers are not susceptible to spoofing.

There is no such thing as complete electronic security. Only degrees.

Go figure.

FYI the military does not use GPS. It uses a parallel system called PPS (Precision Positioning System) that is much more accurate and ... encrypted. Spoofing is way harder on time-sensitive systems (i.e. GPS/PPS) that are encrypted (basically it’s not possible).

Scarecklynews to anyone in the defense biz.

There are numerous ways to defeat such attacks, but they add to the cost. Few if any civilian applications have them.

There could be a market in these to defeat home monitoring bracelets...

I wouldn’t be overly concerned. True, GPS units are very sensitive radio receivers and as such, subject to jamming and electronic countermeasures. However there are features of GPS (implemented in safety critical units such as those used in aircraft but not the low-cost consumer ones - yet) that can further improve reliability. RAIM Receiver Autonomous Integrity Monitoring - is one example.

“Private pilot here, and GPS is a nice luxury, but not a necessity if you know the basics.”

Who needs jammers when you have ME in the right seat. Girl friend was flying, I was checking something on the GPS, about 50 miles from destination. With turbulence, I hit a button unknowingly, I had set a waypoint but I didn’t REALIZE it. When we started down for the field 10 miles short of the real destination I found out that a GPS in the airplane is great but like you said you still need to pay attention to the basics.

GOD, I’m glad my CFI wasn’t there!

The important use for GPS i.e. ICBM guidance, won't be affected. That application has access to the high bandwidth, encrypted navigation info from the GPS birds. It won't a problem for most GPS users either. This "spoof" requires being near the spoof device to overcome your inputs from the actual GPS birds. Unlikely if the GPS is located on your moving vehicle. It might be a cute "cloak and dagger" approach to crash an airplane if you could manage to affix it undetected.

“Scientists at Cornell University”

Correction: “Kids at Cornell University”

They should go to jail.

All those here on FR who were so worked up about businesses and colleges who used cell phone jammers should be wild about this.
