摘要：	The Center for Operational Oceanographic Products and Services (CO-OPS) is committed to providing products and services that support safe and efficient marine transportation, sound environmental management, and effective emergency planning. Numerous CO-OPS products are part of the Physical Oceanographic Real-Time System (PORTS). The PORTS network contains a suite of instruments that measure and disseminate observations of environmental and meteorological parameters and has become a major decision support tool that integrates real-time environmental observations, forecasts, and other geospatial information. Reliable data communication paths are critical to maintaining the high quality products that make up the PORTS network. CO-OPS depends upon telephone lines, line-of-sight (LOS) radios, wireless Internet protocol (IP) and Iridium modems, as well as Geostationary Operational Environmental Satellites (GOES), to transmit data that serve as the backbone of PORTS products. Most systems use at least one of two or more telemetry methods to ensure that realtime data reach CO-OPS servers. However, most acoustic current profilers within the PORTS system do not have a redundant communication path because the message sizes are both large and frequent (transmitted every six minutes). Of the 38 acoustic current profilers that CO-OPS maintains, most contribute to PORTS data, including the 15 that reside on aids to navigation (ATON) buoys.
