Cutting-Edge Positioning, Navigation & Motion Tracking Systems for Marine & Maritime Vessels & Platforms

Inertial Labs is a leading designer and manufacturer of positioning, navigation and motion tracking systems for marine and maritime vessels and platforms. Based on cutting-edge inertial sensing technologies, our high-performance systems feature extremely low SWaP (size, weight and power) footprints.

Our motion reference units and wave sensors are ideal for a wide variety of surface and subsea applications, and our expert team of engineers can advise on the best models for your specific applications and provide full integration support.

Motion Reference Units

3-axis MEMS motion sensors for marine applications

Our MEMS-based Motion Reference Units (MRUs) combine three-axis solid state accelerometers, magnetometers, gyroscopes and barometric sensors to provide a variety of useful outputs for marine applications both above and below the waterline. The advanced high-performance strapdown sensors incorporate a range of specific algorithms for specific platforms including surface vessels, ROVs and AUVs, buoys, cranes, helidecks and more.

Motion Reference Units are available in different models to suit specific accuracy and stability needs as well as output requirements. They can be provided in IP67-rated or underwater 200 metre-rated enclosures. Data can be output in standard industry formats including Kongsberg/Seatex, Teledyne and SMC.

Wave Sensors

Inertial sensing solutions for wave motion & characteristics measurement

Inertial Labs Wave Sensors are MEMS-based inertial sensor solutions designed to meet the marine industry’s requirements for accurate wave characteristics measurement. The advanced strapdown sensors provide a variety of outputs, including wave height, period, direction, energy and more, and can generate spectral data as complete Fourier coefficients and energies sets.

The sensors can be interfaced with external GNSS receivers, gyro compasses and Doppler Velocity Logs (DVL), and are available in two variants to suit different accuracy and output requirements. The WS-PD is also available in a rugged subsea enclosure rated for depths down to 200 metres.
