tile and capable instrument, with optional acoustic Doppler current profle (ADCP) functionality. A bonus for the Xplorer is having instruments that are designed to work seamlessly together and then built and tested together, all by the same company, which means users get optimal performance and one-stop-shop support.

For positioning from the vessel, a Micro-Ranger 2 USBL system, with an AvTrak 6 integrated into the AUV for po- sitioning and telemetry, has been chosen. Built around So- nardyne’s Sixth-Generation (6G) hardware and Wideband 2 digital acoustic technology, Micro-Ranger 2 is an easy to use system that provides ideal support for shallow water op- erations from smaller vessels. Used with AvTrak 6, Micro-

Ranger 2 unlocks tracking, telemetry and vehicle command capability. In addition, Wideband Sub-Mini 6 Plus (WSM 6+) beacons are being employed to support its launch and recovery system. This involves deploying a cage containing the AUV overboard and then through the splash zone to de- ployment depth, where the AUV swims out.
