Inertial Labs WS-PD Professional Dual Wave Sensor

Inertial Labs WS-PD Professional Dual Wave Sensor

Manufacturer: | Categories: ,

The WS-PD Professional Dual wave sensor from Inertial Labs is a high-performance strap-down wave, direction & motion sensor, that determines significant wave height, max wave height, wave period, wave direction, wave energy, directional width, Fourier coefficients, mean spread angle, heading, pitch, angular rates, accelerations, magnetometer data, temperature, heave, heave velocity and positioning for any device on which it is mounted to.



The WS-PD Professional Dual wave sensor from Inertial Labs is a tactical grade MEMS based inertial sensor solution. The Inertial Labs Wave Sensors (WS) Units utilizes solid state 3-axes each of precision accelerometers, magnetometers, gyroscopes and barometric sensors to provide accurate wave characteristics as well as heave, sway, surge, pitch and roll of the device under measure.

Inertial Labs has developed its Wave Sensors (WS) to meet industry wave statistics requirements and also generate spectral data as a complete set of Fourier coefficients and energies. The Wave Sensors (WS) can easily be integrated with a buoy or floating platform controller to transmit data in real time. Through a combination of proven sector expertise and a continued investment in technological innovation, Inertial Labs delivers the optimum balance of price and performance ratio solutions for its customers.

The team of skilled engineers at Inertial Labs will provide their expertise to help users select and configure the WS-PD. Their support team helps set up units for all application bases to satisfy both GNSS enabled and GNSS-denied environments.
