Abstract: The U.S National Data Buoy Center (NDBC) has developed a new wave data acquisition and processing system, called the Wave Processing Module (WPM), using state-of-the-art technologies and the experience accumulated at NDBC over the past 20 years. The WPM is capable of acquiring either directional or nondirectional wave data through various sensors and transmitting the data to various host payloads which, in turn, transmit the data to a shoreside system. The WPM is designed to be compact, inexpensive, expandable, and able to process at high speed. This paper presents the system design of the WPM and describes the WPM prototypes, laboratory tests, and a field test of a prototype WPM deployed on a 3-meter discus buoy. Results from laboratory and field tests show the validity of the WPM design and implementation.
