I got distracted again this morning. I was reading a Zerohedge story about a hedge fund that invested everything in a wireless broadband internet system called LightSquared.

It seems it interferes with GPS landing guidance systems at airports.

Then there is a story about how the airport people discovered this was because some truck driver had a GPS jammer in his work truck for the trucks GPS tracking system. He drove past the airport and it blocked the GPS system.

Airports also use radio beacons. So there is an argument about how good the GPS system is they use but mentions that these jammers are out there.

I'm thinking about the effective radius of these things and how useful that would be in certain circumstances.

Anyone have one? Had any experience etc......

I'm also wondering about radar triggered cameras.

Did a quick search. Came up with these guys.

They have some interesting stuff. Actually some stuff not related to GPS's but WiFi and also some for radio bands.
