Coastal Environmental Systems designed a dual fiber optic loop meteorological system that also measured a number of ocean parameters (salinity, conductivity, water temperature). This weather station was a preliminary design for a project called SMOOS for the U.S. Navy. Coastal was teamed in the competition with TRW and the design was rated the "Best" technically. As TRW was unsuccessful in the larger program (TESS) Coastal did not build SMOOS, however a NATO vessel did purchase a very similar, albeit scaled down design. The NATO ship Alliance was fitted with a Coastal shipboard weather station that measures Wind Speed/Direction/Gust/Sigma Theta at three different points on the ship (port, starboard and aft). Additionally, a sensor suite below decks was inserted into intake water to measure and compute salinity, conductivity and water temperature. Each sensor suite was connected to an Intelligent Sensor Interface (ISI) which processed the signal and digitized it into an RS-422 format. The message was then sent out (when polled from a MicroVAX) on a dual fiber optic loop. The reason for the fiber optics was to eliminate any interference from electronic noise and similarly not to create any electronic noise. The reason for the dual loop is that due to the nature of a ship it might be possible for a cable to be severed. The dual loop ran in different directions and data could be sent or received from either direction thus greatly increasing reliability.
After many years of successful operation the system was upgraded in 2000 when the MicroVAX was replaced by a more centralized LAN. At this same time the WEATHERPAK® was used to replace the sensor suites as it is a COTS product of integrated sensors and easier to maintain, service and install. Each WEATHERPAK® is addressable and is running on an RS-485 shipboard LAN.
