War may effect wardrivers...

That's exactly how dgps works, though automagically.

Just a quick question, does anyone else find it funny that BW spells Iraq the same way as iPAQ?

You'd sooner get better use out of Hussein than Compaq.

yup...

I just read on the kismet mailing list they are degrading the gps signal to be accurate up to 100m, (from 3m)...

Looks like they'll be degrading the GPS accuracy to 100m (instead of 3m)
Bad for wardriving, but in theory if your GPS has WAAS you'll get the
standard accuracy from the ground towers.

Its a fuckin rumor and total BS!

Read the article ...

The summary is basically bimmer owners fear that they can't find their local beer hall because they think that the DOD might turn on Selective Availability. Fucking old Europe!

An the effective resolution of the consumer grade GPS is 15 meters, not 3 meters.

Yes, it is a rumor, but people like to get scared about anything that one person says..

more rumors to spread like butter on bread!

US to disrupt GPS, satellite comms in Gulf?

I once had an interesting discussion with a satellite guy. He said that lauching a ton of gravel in the orbital paths of geosynchronous comm and gps sats could take out significant chunk of the infrastructure and it would take years to recover. I believe China, France, India, and Russia have this capability.

update: well the war is well underway... no significant changes in the degradation of gps accuracy... though the war isn't over yet, we are currently at orange [high] (http://www.homelandsecurity.com/modu...eat&file=index)





though the war isn't over yet, and who knows wtf would happen if the condition changed to severe...

let's just hope we never have to see this:

follow-up

Well, the signal was not degraded and in fact it was selectively improved over the middle east according to this article

There is a brief description on how this was done for all interested.
