Interesting article at GPS world about intentional GPS jamming via /. AS WE ALL KNOW, GPS SIGNALS ARE WEAK. At a receiver's antenna, in the open air, their strength is about -160 dBW or 1 ? 10-16 watts.

This is a nice, compact gps logger that's built around a PIC16F872 and some eeprom chips. It was designed for a particular GPS receiver, but should be easily adaptable to others since the unit ouputs standard sentences at 4800 baud.

TomTom's have been getting pretty cheap. We like 'em because they're nice and hackable. This diy docking station was made from some etched PCBs, a bunch of male pin headers and a bit of hot glue.
