applied acoustics’ Easytrak Nexus 2 Max represents a significant evolution of the company’s USBL positioning technology, re-engineered to address the efficiency and accuracy demands of modern marine survey operations.
As Ben Darling, Positioning Product Line Manager at applied acoustics, explains, the system has been designed specifically around the real-world requirements of today’s survey vessels, particularly those engaged in offshore wind, UXO, and nearshore projects.
At its core, the Nexus 2 Max focuses on simplifying survey operations while improving data quality. The system adopts an Ethernet-based architecture using UDP inputs, allowing multiple sensors to be integrated through a single cable. This reduces onboard cabling, speeds up mobilisation, and supports cleaner survey spaces, an increasingly important factor for smaller vessels and remote operations.
Accuracy improvements are delivered through enhanced time synchronisation and interpolation, ensuring positional data aligns precisely with acoustic responses, even over long ranges. Built with hybrid manned and unmanned surveys in mind, the Nexus 2 Max supports complex asset tracking and future autonomous workflows, positioning it as a forward-looking solution for evolving ocean survey environments.
