River and Harbor Aid to Navigation System (RIHANS) Phase 1-T: System Definition.

Abstract

A low frequency radio navigation system was designed for use within ports, rivers and harbors. The system, operating on the principle of phase comparison much like OMEGA, sequentially radiates four frequencies in the 300 kHz region to provide service to a 50-mile square area. Theoretical analyses indicate that the low frequency RIHANS system is capable of providing position fixed accurate to 50-250 feet, the error dependent on the user's position relative to the transmitters. Limited experiments conducted on a single 12-mile baseline array yielded single LOP absolute accuracies of 30 feet with repeatability of 10-20 feet. (Author)
