Wave Energy, Spectral Data and Fourier Coefficients

Inertial Labs has developed Wave Sensors (WS) to meet industry wave statistics requirements and also generates the spectral data as a complete set of Fourier coefficients and energies. Wave Sensors (WS) are an enhanced, high-performance strap-down Wave, Direction & Motion Sensors, 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 Position for any device on which it is mounted.

The Inertial Labs Wave Sensor (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.

The Wave Sensor (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.
