Flexible Transportation & Maintenance

Both the component system and the mission system utilize a modular design, making it easy to switch between different mission deployments and maintain the USV.

M40 05 shaking  e1553841011702

Lower Noise and Higher data quality

The innovative wave-piercing bottom of the M40 USV can slice through waves to reduce shaking and noise during sailing which allows instruments to collect data of higher quality.

Automatic Multi-purpose Survey

  • Both the USV and the survey instruments are operated by the base station. Navigated by the GNSS positioning system, the USV can autonomously conduct pre-programmed multi-purpose surveying missions and send back data in real-time.
  • Operators can also control the USV manually within a distant of 2 km by using a remote controller.
