The WS-PD is an advanced MEMS-based wave sensor designed to meet the marine industry's requirements for accurate wave characteristics measurement. The strapdown unit outputs wave height, period, direction, heave/surge/sway, pitch and roll, and can generate spectral data as complete Fourier coefficients and energies sets. It also features an RTK-capable dual-antenna GNSS receiver for high-accuracy heading, position and velocity output.

The sensor can be interfaced with other external sensors such as Doppler Velocity Logs (DVL), and can also be easily integrated with platforms such as buoys to enable real-time data transmission. The WS-PD is available in an IP67-rated housing or a special rugged subsea enclosure rated to depths of 1000 metres.
