Multi-function Marine Survey USV
The L25 unmanned surface vessel (USV) can carry up to 200kg of instruments to
conduct multi-purposed hydrographic & geophysical survey.
Shallow Draft to Explore Wider Area
The L25 unmanned surface vehicle (USV) has a light load draft of 0.6m and full payload draft of 0.8-0.9m, making it ideal for autonomous surveys in super shallow water areas (down to 0.6m) that are inaccessible to manned vessels.
Its shallow-draft design enables precise bathymetric mapping and coastal operations in challenging nearshore environments.
Extendable Endurance to Cover Longer
The standard range of L25 unmanned vessel is 65h@4kns, extendable to 130h@4kns, significantly surpassing similar-sized manned boats.
Towing System Supports Towing Survey
The towing system support side scan sonar towing survey with autonomous vessel, cable length up to 200 meters;
Auto lifter protects instruments wet ends and offers greater payload capacity.
Outstanding Payload Capacity
With multiple mounting positions and mounting mechanisms, the L25 unmanned vessel can carry 2-4 mission payloads simultaneously.
Integrated Multi-Network Communication
The communication system can integrate four networks, which supports both daily and emergency communications. satellite communication is optional for safer long-distance operations.
Integrated Map Display
The integrated map display function uses electronic chart, satellite map, or hybrid map (electronic charts for ocean areas and satellite maps for land areas) as the base layer, and can simultaneously merge and display radar, AIS, and map drawing information, offering exceptional situational awareness, risk perception, and assist precise task setup.
Autonomous Control with High Precision
Radar, HD camera and AIS sensing enabling highly sensitive environmental perception.
Autonomous navigation algorithm, advanced obstacle avoidance algorithm and propulsion control algorithm applied to minimize risk of collision.
