Bayonet AUGVs:
Reliable, Robust, and Ready for Any Challenge
Designed for myriad tasks throughout the full expanse of the maritime businesses, Greensea IQ’s equipment and technology might be just the ticket for more efficient and accurate dredging results.
Nearshore environments present unique challenges for surveying and inspection due to their dynamic conditions and shallow water depths. These areas are critical for understanding coastal morphology, sediment transport, and infrastructure stability. Traditional methods of collecting bathymetric and topographic data often face limitations in accessibility, safety, and efficiency. Nowhere is that truer than for the dredging industry.
The Bayonet series of autonomous underwater ground vehicles (AUGVs) is the result of years of research and development aimed at creating a platform that thrives in nearshore environments where traditional systems fall short. These vehicles are purpose-built as an advanced solution for seamless nearshore inspections and real-time kinematic (RTK) surveys. Designed for operation in the surf zone, Bayonet AUGVs bridge the gap between land-based and marine surveying by providing highly accurate data across beach faces, surf zones, and very shallow waters.
Performance in the Most Challenging Environments
Operating seamlessly from the seabed to the beachhead, the Bayonet AUGVs excel in conditions that challenge other systems. With advanced navigation capabilities powered by Greensea IQ’s proprietary IQNS, the Bayonet AUGVs deliver unmatched precision in both GPS-enabled and GPS-denied environments.
The B350 is the largest vehicle in the Bayonet class, engineered for the heaviest payloads and the harshest environmental conditions. Its scalable architecture allows the chassis to be customized to specific payload requirements, making it an ideal choice for missions demanding significant capacity and robust performance. Whether for complex scientific research, extensive military operations, or challenging commercial tasks, the B350 is equipped to deliver unparalleled results.
Key features of Bayonet AUGVs include:
-
Amphibious Capability: Designed to traverse surf zones and operate in water depths of up to 100 meters.
-
When equipped with RTK antenna and advanced navigation, Bayonet AUGVs demonstrated a total vertical uncertainty (TVU) of less than 6 cm, even in variable wave conditions.
-
Payload Flexibility: With a large open deck and modular design, the Bayonet AUGV can accommodate a variety of sensors and tools, including forward-looking sonar, magnetometers, and sub-bottom profilers.
-
Robust Construction: Built to withstand harsh environments, the vehicle’s rugged design ensures reliability during extended missions.
Whether deployed for coastal mapping, environmental surveys, or in preparation for a major dredging event, Bayonet AUGVs adaptability makes it an indispensable tool for operators worldwide. Its field-swappable battery packs and compact dimensions enable rapid deployment from standard vehicles, enhancing operational efficiency.
