Overview

Nano. Our smallest ever USBL transponder.

Dive into underwater exploration with Nano. Nano transponder is our smallest ever USBL transponder capable of being used within our Ranger 2 USBL family. Suitable for AUV, ROV and diver operations, as well as custom integration with our OEM model. Whether you’re conducting environmental surveys, engaging in coastal science or military operations, Nano’s unmatched reliability and performance keeps you connected and in control beneath the waves.

Overview

Nano operates in the Medium Frequency (MF) band, so it’s compatible with our family of Ranger 2 USBL topside systems; Micro, Mini and Standard.

Measuring in around 160 mm in length, 55mm in diameter and weighing in at under 200 grams in water – depending on the exact version you’re using – Nano is small enough to fit on the smallest of vehicles and light enough for a diver to barely know they’re carrying one.

Nano’s built using the same signal technology platform you’ll find in our award-winning 6G product line – Wideband 2. So you can expect reliable acoustic communications in all operating environments, accurate position fixes and a continuous stream of location updates.

At a glance

2nd generation design, extended battery life and 500 m depth rating
NFC, connector and OEM housing options
NFC version is just 160 mm long by 55 mm in diameter. USBL transponders don’t get much smaller than this
Depth rated to 500 m
Easy to fit to divers, ROVs, equipment and AUVs

Nano features a 90-day quiescent battery life, ideal for long-term deployments and recovering lost assets. Nano’s battery lasts up to 12 hours, even when being actively tracked with one second position update rate.

The NFC Nano features a unique connector-less design that is recharged and programmed via the Nano Docking Station. The NFC technology allows full configuration of the Nano whilst maintaining its rugged “strap on and go” form factor.

The cabled Nano features an industry standard Subconn connector allowing the Nano to be permanently powered, and can also be used in Responder mode.

When purchasing a Micro-Ranger 2 USBL system, we include two Nanos as standard. You’re able to choose between the NFC or connector version at no additional cost.

For vehicle programs and integrators, the Nano OEM when paired with an OEM transducer provides all the functionality of the housed transponders, in a form factor that can be mounted in any system.

Nano has an inbuilt depth sensor and is a 500 m depth rated unit.
