Gavia AUV
The Gavia AUV from Teledyne Marine is a compact, self-contained autonomous underwater vehicle developed for expeditionary missions requiring low logistical overhead and rapid field configuration. Rated for operation to either 500 m or 1,000 m, the vehicle uses interchangeable modules that allow batteries, payloads, and mission equipment to be exchanged between dives without installing or recalibrating external peripherals. Its 200 mm-diameter form factor supports transport by a two-person team, deployment from vessels of opportunity or shore locations, and shipment for dispersed operations. Up to three rechargeable battery modules can be installed, while Iridium connectivity provides over-the-horizon communications when the vehicle is at the surface.
Available payloads span synthetic aperture sonar, side-scan sonar, multibeam echo sounding, sub-bottom profiling, cameras, environmental instruments, custom sensing packages, and configurable autonomy functions. For defense missions, these options support mine countermeasures, rapid environmental assessment, search and recovery, and anti-submarine warfare training. Navigation combines a DVL-aided inertial navigation system with DGPS readiness, direct sound-velocity measurement, and optional USBL assistance for maintaining positional accuracy during extended deployments. Field-swappable modules, compact handling requirements, and configurable sensing allow small teams to adapt the same platform to changing survey, security, scientific, and operational tasks.
