For those of you who don't know about this yet, the Atak has a magnetic compass, wheel rotation sensors on the front wheels, a processor, a tape cassette full of map data, and a clever dead-reckoning algorithm which uses the map data to compensate for the errors in dead-reckoning. The algorithm was developed by a recent winner of the transanlantic solo sailing race, who is considered an authority on dead-reckoning techniques. A nice little unit, and much cheaper than the GPS-based systems. I've heard that GM is coming out with these next year. John Nagle
