The new Nexus 2 is the second generation of Easytrak digital USBL systems designed as a highly advanced positioning and tracking system that is quick to deploy and straightforward to operate.  Featuring AAE Sigma 2 acoustic protocols, the Nexus 2’s digital Spread Spectrum transmissions provide a secure acoustic link with very low susceptibility to interference, enabling precise and reliable positioning over an extended operational range.

Able to determine the positions of up to 16 dynamic subsea targets simultaneously, Nexus 2 is ideal for many deep or shallow water applications where multiple assets are to be tracked.  These operations can include UXO surveys utilizing several magnetometers or sidescan sonars, diving operations, and for use at offshore worksites where several vehicles may be in use concurrently.

Enhancements to the design of the Nexus 2 transceiver have helped to create an extremely accurate USBL system, boasting positioning accuracies of 0.2% of slant range and a bearing resolution of 0.01 degrees.    Optimum system performance is delivered when used in conjunction with AAE’s 1100, 1200A or 1300A Series transponders, however versatility is assured due to its compatibility with legacy products and transponders from third party manufacturers.

Embedded as standard within each Nexus 2 system are a comprehensive range of software features and survey tools such as the geo-referenced graphical overlay function and EasyCal 2 calibration tool with AutoCal Wizard.  These features are provided to ensure swift and easy set to work procedures, saving valuable time and project costs.
