Initially developed for the United States Navy, the TRIAXYS™ Mini Directional Wave Buoy is a precision instrument incorporating advanced technologies that make it an easy to use, rugged, and economical buoy for accurate measurement of directional waves. This small (0.6m diameter) and lightweight (60kg) buoy is easily deployed by two people from virtually any size of vessel.

The TRIAXYS™ sensor unit is comprised of three accelerometers, three rate gyros, a fluxgate compass, and the proprietary TRIAXYS™ Processor. The TRIAXYS™ Sensor has recently been upgraded and now provides continuous wave sampling, support for any telemetry, up to 50 Hz motion sampling and up to 32GB (>5 years) of data logging capacity. The "next wave" of the TRIAXYS™ Sensor also uses the WatchMan500™ controller, which is the core technology used in other AXYS monitoring systems.

TRIAXYS™ is also easy to handle during deployment as it can be rolled off a ship deck without any concern for sensor damage due to spinning.

Wave and sea surface temperature data are collected, processed and logged on the buoy and then transmitted via VHF, cellular or satellite telemetry to a base station hosting AXYS WaveView™ software which allows for full presentation and archiving of data along with diagnostic utilities.

Standard mooring configurations specially designed for wave buoys are available for water depths up to 150m. AXYS Services Department can design custom moorings for water depths in excess of 150m. Upon activation TRIAXYS™ Directional Wave Buoys can be equipped with WatchCircle Alarm to provide notification if a buoy moves off station, and when teamed with satellite telemetry it provides tracking information for buoy recovery.

Please see the TRIAXYS Mooring Requirements Page for information, calculations and recommendations on moorings for TRIAXYS™ Wave Buoys.

Buoy training, commissioning and deployment is available upon request from AXYS Customer Service department.
