Why AvTrak 6 Nano is perfect for your operations
For energy
It's not just for AUVs. Integrate AvTrak 6 Nano with your seabed nodes, you can create a network of sensors that can position and communicate with each other.
For defence
Its small form factor and ability to enable surface to AUV or UUV-to-UUV comms, makes it a prime option for swarm or squad robotics operations.
For science
AvTrak 6 enables an AUV to undertake simultaneous USBL tracking and telemetry with a research vessel, as well as AUV-to-AUV communications.
Overview
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.
Use it with our popular MF USBL Ranger 2 family to track AUVs or seafloor nodes. Then use the Sonardyne Messaging Service (SMS) to exchange status messages with the USBL or other AvTrak 6 Nanos in your vicinity. With hundreds of units in the field, AvTrak 6 Nano is ideal for AUV swarms.
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.
AvTrak 6 OEM Nano redefines nano, measuring at just 95 mm x 43 mm, you won’t find a smaller OEM AUV transceiver with this much capability. Its omni-directional transducer is small too, at 49 mm diameter and 72 mm long.
Equipped with AvTrak 6 Nano, your UUV will receive unlimited data and share messages every navigation cycle when used with Ranger 2. By supporting the integration of a data payload inside every navigation signal, this allows more data to be transferred to and from UUVs with fewer transmissions which ultimately reduces power consumption and increases mission endurance.
A common configuration enables the USBL system to communicate with a squad of UUVs equipped with AvTrak 6 Nanos, broadcasting to all the position of each member of the squad 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. Either for short burst communications or full large quantity data upload from seabed monuments.
