A precise navigation system has been proposed for use in mine and amphibious warfare. It is a continuous-wave phase comparison system, which derives its information from the change in phase between two stable oscillators as the distance between them is varied. A receiver, with very good phase versus temperature stability, was designed for this system. A test circuit was designed to field monitor any receiver phase changes which do occur. A method to frequency lock several oscillators to a master was also devised. Tests were run to determine the stability of the receiver, and the feasibility of the system.
