Abstract:
The National Data Buoy Development Project has been undertaken by the U.S. Coast Guard to satisfy a critical need for additional marine environmental data. The concept of using a network of buoys to collect such data has been endorsed by a number of national committees and funds supporting the development were appropriated by Congress for Fiscal Year 1970. A reliable telemetry subsystem is essential to the success of the system as a whole. In this paper, a computer model developed at ITS for simulating the performance of a telemetry system using six frequency bands in the HF portion of the radio spectrum has been described. It is useful in both the design and operational phases of system development. During the design phase, it enables the systems engineer to efficiently make tradeoff studies among parameters over which he has control (e. g. , transmitter power output, modem type, antenna gains and patterns, number and location of shore stations, and frequency assignments) for different levels of solar activity, season, geographic distributions of drifting buoys, and other factors over which he does not have control. During the operational phase it can be used for assigning frequency, station, and time resources and evaluating actual performance. Sample results obtained from studies of a hypothetical data buoy network have been given.
