Nano - small ROV, Drone, AUV & Diver Tracking

Sonardyne International

Description

The Wideband Nano Transponder is specially designed for short duration acoustic positioning of divers or small underwater vehicles. The small lightweight wireless rechargeable transponder design allows for easy, unobtrusive attachment to a diver or vehicle. The Nano Transponder connector-less design is recharged and programmed via the Nano Docking Station. It takes around 12 hours to fully recharge the high capacity battery. The standard instrument is depth rated to 500 m and has an acoustic source level and beam-shape that is designed to operate over a 750 m slant range under normal conditions. The Nano Transponder operates in the Medium Frequency (MF) band so it is compatible with Sonardyne’s Mini-Ranger 2 6G® Wideband USBL system. The Nano transponder is available with and without a pressure sensor depending on the operating requirements. The pressure information can be used by the Mini-Ranger 2 system to depth aid the USBL position. The wireless connection enables several operating parameters to be changed, like the acoustic address, navigation power and turn-around time using the programmer. In addition, using wireless energy harvesting, the instrument can also be put into and brought out of a storage mode where the battery is disconnected. Test functions via the wireless connection include: configuration, battery status, initiate power-down or wake up, acoustic test signal transmission and firmware update.
