● High-Precision Measurements
Utilizing GNSS-based high-precision positioning and advanced algorithms, the Drifter delivers accurate and stable measurements of wave height, wave direction, wave period, and other key parameters.
● Cloud Platform Integration
All collected data is transmitted via Iridium satellite communication to the cloud platform, offering seamless access, real-time query, and convenient data download.
● Modular and Flexible Design
Featured with a modular design, it allows flexible customization of communication modules, battery capacity, and mooring components according to deployment requirements.,which simplifies installation, maintenance, and component replacement.
● Long-Endurance Operation
Equipped with high-capacity lithium batteries and optimized for low-power operation, the Drifter supports long-term, continuous offshore monitoring. Battery capacity can be extended to meet longer mission durations.
