Miros dry sensor for accurately measuring surface currents

The Miros Wavex virtual sensor provides accurate wave and current measurements, using data from standard X-band marine radar.


At a glance

  • Accurate, dry sensor for measuring ocean surface currents
  • Can be interfaced with existing X-band marine radar
  • Optimises vessel performance for improved fuel economy

Solution status


Ocean surface characteristics are a vital indicator for monitoring a vessel’s fuel consumption, performance and hull condition. Traditional methods of measuring surface currents use instruments that are submerged in water. Such units are costly to install and maintain, and are susceptible to damage and loss. They are also prone to biofouling, which affects function.

Moreover, surface currents are themselves affected by a vessel’s motion, which can further complicate data capture.

A novel way of measuring the ocean surface

Wavex® is a dry sensor that utilises X-band navigation radar technology for accurate and reliable wave parameters. These include 2D spectrum, surface current magnitude and direction, and speed through water calculations.

The sensor delivers highly accurate real-time data, undisturbed by vessel motion and propellers. Wavex can be easily interfaced with existing marine X-band radar, without any need for calibration. The sensor is operative at all ship speeds as well as from fixed locations.

Concrete benefits

The Wavex® sensor provides accurate and reliable wave parameters, which are vital for optimising fuel consumption in vessels and reducing associated emissions. These are also key parameters for vessel performance evaluations and hull performance monitoring systems, as well as for scheduling maintenance.

Moreover, Wavex helps to reduce weather-related vessel damage and improve passenger comfort, while eliminating the costs related to installing and maintaining underwater equipment.

Market potential

The Wavex® sensor is suitable for all types of vessels seeking to optimise fuel consumption and maintenance intervals (such as for hull cleaning), among other things.

Miros is a technology company that specialises in measuring the ocean surface. The company has provided sensors and systems for environmental monitoring to the global offshore and maritime industries for more than 35 years and has a presence in 28 countries around the world.
