Abstract:	Microprocessors and their application to navigation systems are discussed. A survey of presently available microprocessors is presented, which indicates that only the simplest and slowest devices currently offer any cost advantage over other technologies. A Loran-C receiver using a microprocessor de- sign with a total of 70 integrated circuits is described. A floating point interpreter designed to simplify programming navigational computations on a four bit microprocessor is also described. A coordinate conversion program for Loran using the interpreter has been developed, which uses 4096 words of 8 bit program memory and will compute latitude and longitude to within 50 feet in 22 seconds.
