AvTrak 6 Nano is a compact acoustic transceiver developed for Autonomous Underwater Vehicles (AUVs) requiring tracking, telemetry, navigation aiding, and emergency relocation capabilities within a highly space-efficient form factor. Designed for micro and small AUV platforms, the system combines USBL tracking support, acoustic communications, and mission coordination functionality into a single compact device suitable for defence, offshore energy, and ocean science operations. When integrated with the Ranger 2 USBL family, AvTrak 6 Nano enables simultaneous vehicle tracking and robust bidirectional communications between AUVs, vessels, and seabed assets.
Built on Sonardyne’s 6G hardware and Wideband 2 digital acoustic architecture, the transceiver delivers reliable low-latency communications and positioning performance for swarm robotics, coordinated AUV missions, and seabed sensor networks. The system supports telemetry data rates from 200 to 9,000 bps, allowing efficient transfer of navigation data, vehicle status updates, and operational messaging with reduced acoustic transmissions and lower power consumption. Available in housed and OEM configurations, AvTrak 6 Nano integrates easily into compact autonomous platforms while supporting AUV-to-AUV communication, remote navigation aiding, and distributed underwater sensor operations.
Depth rated to 500 metres, the system provides tracking and communication ranges of up to 3,000 metres with range precision better than 15 mm. The compact housed variant measures just 192 x 55 mm, while the OEM version further reduces integration size to only 95 x 43 mm. Integrated omni-directional transducers, low power consumption, and an emergency battery life exceeding 90 days make the platform particularly suited to long-duration and low-logistics autonomous underwater missions.
