Could < > someone tell me what to do with this thing? Would it be useful in a ca < > an airplane? (I have neither) < < Loran is a system of radio transmitters that ships and planes use to < navigate by triangulating the direction of the signals from two or < more stations. Can't thing of too much use for it in a car, unless < you're going _way_ off-road. It's loran C, still in use for aircraft and ships that cannot afford or do not yet have NAVSAT(GPS) hardware. IT's basically a specialized 100khz reciever and signal processing system coupled to a microporcessor to translate LOP to lat/long. Accuracy better than 1mile and typicaly .2mile. I have a smaller one in my plane and still use it. I wouldn't mind having one of the old TIs as they were amoung the first commercial loran C. Allison
