USV2 Wave Glider
Solar-Powered Uncrewed Surface Vehicle (USV)
To date, the company has completed the mass production and delivery of over 280 wave glider systems, providing ocean observation, monitoring, and sensing services to more than 100 scientists from over 20 marine research institutions.
These wave gliders have successfully endured 17 typhoon events in the Northwest Pacific Ocean and the South China Sea, accumulating a total effective operational distance exceeding 200,000 km. Their survivability under extreme sea-state conditions has been fully validated.
The successful development of the USV2 platform represents a revolutionary technological upgrade to the wave glider system, significantly enhancing overall platform performance, payload capability, and mission functionality.
Overview
Wave Glider USV2
Key Features:
- Hybrid Propulsion – Wave energy and auxiliary thruster enable energy-efficient, long-endurance missions.
- High Payload Capacity – Supports acoustic, optical, electrical, and magnetic sensors for versatile ocean monitoring.
- All-Weather, Long-Duration Operation – Solar and battery power ensure reliable performance in Sea State 1–4.
- Cross-Medium Real-Time Communication – Provides surface-to-underwater data relay and secure telemetry.
- Autonomous Navigation & Station-Keeping – Precise path following, virtual anchoring, and networked formation operation.
Standard Configuration
Scientific Payloads
The Wave Glider can be equipped with a wide range of scientific payloads, including meteorological stations, laser Doppler wind lidar, atmospheric duct sensors, wave sensors, CTD (Conductivity–Temperature–Depth) sensors, temperature and salinity winches, ADCP (Acoustic Doppler Current Profilers), multi-parameter water quality sensors, hydrophones, magnetometers, vision-based recognition systems, and AIS receivers.
These payloads enable missions such as marine meteorological observation, tsunami and earthquake monitoring, marine mammal and biological monitoring, and offshore energy exploration. In addition, the Wave Glider can carry underwater acoustic communication modems to perform surface-to-underwater data relay and communication gateway missions.
Unique Capabilities
The Wave Glider features self-sustaining energy supply, global positioning, satellite communications, and autonomous navigation. It is capable of autonomous navigation along predefined routes or virtual anchoring around designated locations, enabling long-duration, wide-area unmanned continuous survey operations (up to 10,000 km per year).
In addition, the platform supports virtual station-keeping at fixed sea-surface locations, providing data relay and communication gateway services for underwater and surface-based systems, as well as long-range real-time data transmission to shore-based control centers.
