Comparative results for GPS, Loran, and Omega marine navigation
Abstract
Single frequency, C/A Code, Phase-I GPS was characterized from data collected from a NAVSTAR-GPS Z-Set receiver in operation since 1980. It was found that the Standard Positioning System (C/A Code only) is a viable replacement for Loran-C in the harbor and harbor-entrance region only if the full, inherent accuracy of GPS-SPS is provided to the civil user. It is concluded that denial of accuracy or selective availability schemes routinely applied to GPS will not only degrade the system to less than Loran-C accuracy but would set a harmful precedent in marine radionavigation systems.
