Brizo – Wave Monitoring & Tide Gauge using GNSS
Measure Both Wave Height and Direction
The Brizo is a highly accurate (1 cm, 3°) directional wave height sensor for placement on moored buoys. Utilizing the lowest power, all signal Global Navigation Satellite System (GNSS) receiver for measurements, the Brizo can relay parameters and spectra for wave periods of 1.6 to 33 seconds on a <1 W power budget.
The Brizo has optional integrated telemetry options that suit your deployment along with built in data logging. The communication modules along with the GNSS antenna allows for simple sensor addition to existing oceanographic and navigation buoys, adapting them as wave measuring modules.
Over the course of the September of 2017 two GNSS based Brizo wave height and direction sensors were deployed on buoys near Halifax Harbor, Nova Scotia, CANADA. One was on an existing environmental buoy (Halifax SmartAtlantic Buoy) and the other on a Canadian Coast Guard navigation buoy. The environmental buoy deployment was co-located with an accelerometer based Axys directional wave height sensor. Overall both Birzo deployment showed a high correlation with the wave spectra parameters as reported by the Axys buoy.
