AXYS offers TRIAXYS, WatchKeeper, 3 Metre and NOMAD platforms with configurable wave, current, weather and environmental sensors. WatchMan500 links sensor, power and telemetry modules with APS/DMS data handling. Hull, payload, power, mooring and communications differ by model. Named NOAA and ScottishPower configurations provide operational proof; Ripple edge-vision work remains development rather than an existing fleet function.
