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.
