Wave Sensors (WS)


Buoy on Side The Inertial Labs Wave Sensor (WS) product line is the latest release of tactical grade MEMS based inertial sensor solutions. In 2016 Inertial Labs responded to the research and development sectors of many biology and geographic analysis facilities for a device that is able to monitor Ocean Characteristics for Maritime Observation and Analysis. 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 Sensor (WS) products are an enhanced, 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 Position for any device on which it is mounted to.

The Inertial Labs team of skilled engineers provides expertise to help users select and configure from the models available: WS-E, WS-PD. Our support team helps set up units for all application bases to satisfy both GNSS enabled, and GNSS-denied environments.

Wave Sensor Use Cases


The Inertial Labs Wave Sensor has been commonly used for the following applications. Visit our Marine Use Cases page to see more detail on specific Marine projects we have been a part of.
Ocean shore

Ocean Characteristics Monitoring

The Wave Sensor meets industry wave statistics requirements and generates spectral data as a complete set of Fourier coefficients and energies. Use the WS to monitor and record or communicate using RF in real time to a base station Wave Parameters and Ocean Characteristics such as: Significant Wave Height, Max Wave Height, Wave Period, Wave Direction, Wave Energy, Directional Width, Fourier Coefficients, Mean Spread Angle and much more.

Dynamic Positioning on Research Buoy’s and Vessels

Mount using the IP67 or Subsea enclosure (rated to a minimum of 200 meters) on research buoy’s and vessels (autonomous and manually operated). Communicate in real time using Radio Frequencies (RF) or take advantage of the WS-PD and pair with an Real Time Kinematic (RTK) Base Station from Inertial Labs for RTK communications. Ideal for Dynamic Positioning (DP-1/2/3) applications requiring but not limited to all common GNSS constellations (GPS, GLONASS, GALILEO, BeiDou, QZSS, NAViC, AltBOC, SBAS, DGPS, RTK).

University Oceanology Studies

Partnering with colleges and universities around the globe Inertial Labs offers the Wave Sensor and a development kit bundle which includes the sensor, all cables and the Graphical User Interface; all with a educational discount. Many schools and research facilities have taken advantage of these bundles including: Texas A&M, Tel Aviv University, Penn State University, Nagaoka University of Technology, Virginia Tech, Quebec University and Seoul National University.


Supported Hardware for Wave Sensor


Mapping Software

The Inertial Labs Motion Reference Unit has been designed to be compatible with a number of different solutions. For hydrographic or bathymetric surveying, integration is support for Single Beam and Multibeam Echo-Sounders (SBES or MBES).

Additionally, take advantage of sensors that are already available on your platform and integrate with the MRU product line to increase performance and navigational accuracy. Supported external sensors include: Airspeed, Wind-speed, External Gyro-compass, Velocity Sources (Doppler Velocity Logs) and External GNSS Receivers (Single or Dual Antenna).
