This report documents the findings of a national mail survey of civilian marine and terrestrial users of federally-operated Radionavigation Systems (RNS). The main objectives of the survey were to gather empirical data on the use pattern of current RNSs and on user predisposition towards proposed satellite-based systems. Three populations were targeted: owners of boats 26 feet and above length overall, U.S. parent companies owning U.S. or foreign flagged vessels and U.S. terrestrial surveyors and mappers. The survey was conducted in 1988 on behalf of U.S. Coast Guard by the Transportation Systems Center; the overall response rate was 61% of the total sample.
