AvTrak 6 Nano may be our smallest acoustic transceiver, but its features and performance are anything but. It’s built on the same 6G hardware and Wideband 2 digital signal architecture found in its larger cousin, AvTrak 6, all packed into the smallest possible form factor.

AvTrak 6 enables an AUV to undertake simultaneous USBL tracking and telemetry with a research vessel, as well as AUV-to-AUV or UUV-to-UUV communications. This capability, along with its size, makes it a prime option for swarm or squad robotics operations.

Its bi-directional acoustic modem has user selectable data rates of 200-9,000 bps.  It has wide voltage input range and multiple communication methods for robotics integration and is available as a housed variant or OEM for integration into vehicles.

A common configuration enables the USBL system to communicate with a squad of UUVs equipped with AvTrak 6 Nanos, broadcasting to all the positions of each squad member to aid the navigation solution and improve their situational awareness. Each UUV then replies in sequence with status information.

AvTrak 6 Nano can also be used to enable UUV-to-UUV communications and choose from seven telemetry schemes ranging from 200 bps to 9,000 bps of effective user bandwidth. This is suitable for either short burst communications or full large quantity data upload from seabed monuments.

It's not just for AUVs. By integrating AvTrak 6 Nano with your seabed nodes, you can create a network of sensors that can position and communicate with each other.  Use it with our USBL Ranger 2 family to track the nodes, then use the Sonardyne Messaging Service (SMS) to exchange status messages with the USBL or other AvTrak 6 Nanos in your vicinity. 

AvTrak 6 Nano measures just 192 x 55 mm, you won’t find a smaller AUV transceiver with this much capability. It has an operating range of 3,000 m, a depth rating of 500 m and full SMS and Modem functionality.

It’s a small product with huge capability. AvTrak 6 Nano provides navigation aiding, tracking, communication and mission planning – all in one incredibly small package. Fit it, and your micro or man-portable AUV will be equipped to undertake simultaneous USBL tracking via a surface vessel and robust telemetry for AUV-to-vessel and AUV-to-AUV communications.

AvTrak 6 provides tracking, communications, and emergency relocation in one instrument.  When used with a Ranger 2 USBL, it will track your AUV’s every move. As you’d expect from our products, AvTrak 6 is also optimised for our Ranger 2 robotics pack for aiding navigation systems with remote position outputs.
