Nano USBL transponder (Second generation)

USBL transponder (Second generation)

Nano from our Technology Partner Sonardyne is designed to track where divers, man-portable AUVs, towed platforms, underwater drones and ROVs are throughout their mission. Visit Website Contact

Nano is Sonardyne’s smallest ever Ultra-Short Baseline (USBL) transponder designed to track divers, man-portable AUVs, towed platforms, underwater drones and ROVs throughout their mission.

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

Measuring around 160 mm in length, 55 mm in diameter and weighing under 200 grams in water – depending on the exact version you’re using – Nano can fit on the smallest of vehicles or can be carried by a diver.

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

Nano features a 90-day quiescent battery ideal for long term deployments and recovering lost assets. When being actively tracked it gives more than 12 hours of battery life at a position update rate of once a second.

When purchasing Sonardyne’s Micro-Ranger 2 USBL system, two Nanos are included as standard. Users can choose between the NFC or connector version at no additional cost.

Key features:

  • 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
  • Depth rated to 500 m
  • Easy to fit to divers, ROVs, equipment and AUVs
