An Autonomous GNSS Wave Sensor Module for Deployment on Existing Buoy Infrastructure : Comparison and Validation of Co-Located GNSS and Accelerometer Directional Wave Sensors

For this paper a standalone OEM (Original Equipment Manufactuer) GNSS wave sensor module is co-located on an existing accelerometer-based three-meter diameter disc wave buoy for statistical comparison. Additionally, a GNSS wave sensor is placed on an existing, already deployed, nearby navigational buoy 700 meters away to assess suitability as a platform for a GNSS directional wave height sensor. Both sensors were deployed in 30 meters depth of water in Herring Cove, Nova Scotia, Canada.
