Nano Transponder is a compact Ultra Short Baseline (USBL) transponder developed for underwater tracking, positioning, and acoustic communication across AUV, ROV, diver, and towfish operations. Designed for use with the Ranger 2 USBL family, the system combines lightweight construction, compact dimensions, and reliable acoustic performance for subsea missions where space, weight, and endurance are critical. Suitable for environmental surveys, coastal science, offshore operations, and military applications, Nano provides accurate position updates and dependable underwater tracking in a highly portable form factor.
Built on the same Wideband 2 signal technology platform used across the company’s 6G product range, Nano delivers low-latency acoustic communication, robust signal performance, and reliable positioning data in challenging underwater environments. Available in NFC, connector, and OEM variants, the transponder supports flexible deployment options ranging from diver-carried tracking devices to fully integrated autonomous vehicle installations. The unit is depth rated to 500 metres and offers up to 12 hours of operational battery life at one-second update rates, alongside a 90-day listening life for long-term deployments and asset recovery missions. Its compact housing, lightweight polymer construction, and connector-free charging option make Nano particularly well suited to small underwater vehicles and portable subsea tracking applications.
