MELODI
MELODI is a cutting-edge marine device designed for precise real-time measurement of essential ocean parameters. This affordable, eco-friendly drifter monitors sea surface variables such as currents, waves, and temperatures, supporting maritime operations, research, and safety.
Comprehensive Ocean Observation Solution
Combining precision and versatility it is suitable for a wide range of applications, from supporting maritime navigation to environmental monitoring and offshore energy projects, helping deepen understanding of ocean dynamics.
Measured parameters
Sea Surface Currents (GNSS)
Significant Wave Height (SWH)
Sea Surface Temperature (SST)
Wave Spectra (0.02 -0.8 Hz) (WS)
Roadmap 2025: Wind, Atmosphérique pressure, Sea surface salinity
Practical Design for Easy Deployment
With its compact, transportable design, MELODI allows for effortless handling and deployment from any vessel. Ready for immediate use, it enables quick and simple deployment for real-time ocean monitoring.
Connectivity
24/7 satellite connectivity (Iridium) ensures real-time ocean tracking and uninterrupted data access. Two-way communication enables remote adjustments to sampling for flexible and responsive operation, providing seamless ocean monitoring.
Roadmap 2025: 4G/5G and Non-terrestrial networks NB-IOT
Eco-Conscious Design
MELODI’s hull is made from bio sourced, biodegradable aliphatic polyester, significantly reducing microplastic generation and minimizing environmental impact, aligning with sustainability values.
