The purpose of this report was to describe the methodology used in developing the First Coast Guard District (CGD1) Traffic Model and to document the potential National Distress System (NDS) voice and data traffic forecasted for the year 2001. The NDS was a network of about 300 remotely-controlled very high frequency (VHF) frequency modulated (FM) radios and antennas used for monitoring the maritime distress frequency (CH 16-156.8MHz) and for providing distress, safety, and United States Coast Guard (USCG) command and control (C 2 ) communications coverage. The USCG was researching alternative
communications systems for potential use in the modernization of the NDS. A contributing factor to selecting an alternative system was the amount of traffic capacity needed. As part of this effort, a baseline model of NDS communications in the CGD1 was developed to provide a reference for forecasting potential future NDS traffic volume.
Coast Guard personnel, who used National Distress System (NDS) daily in the performance of their profession, were among the most knowledgeable NDS use...
The U.S. Coast Guard must routinely interact with other (Federal) government agencies (OGA), State and Local agencies, and various public safety organ...
