TRovNav 5 is a highly configurable, tri-band acoustic transceiver designed to support a family of remote transducers operating in the LF, MF and EHF frequency bands.
ROVNav 6 is a 6G® Wideband®2 ranging and telemetry Long BaseLine (LBL) transceiver specifically designed for installation on work class ROVs.
Its high power output and Sonardyne Wideband® 2 signal processing offers improved range and acoustic performance in challenging conditions such as on noisy vehicles or in multipath environments.
ROVNav 6 is also a fully compatible USBL responder or transponder compatible with Sonardyne Wideband® 1 and 2 USBL systems as well as HPR400 mode. The internal Lithium-ion rechargeable battery pack also enables emergency transponder mode, so if the umbilical and therefore power is cut to the ROV it can still be located by USBL.
The rugged Omni-directional remote MF transducer makes installation on an ROV easy. ROVNav 6 is designed to be rugged though relatively lightweight. It also utilises robust underwater connectors. ROVNav 6 supports a range of internal sensors including; strain gauge pressure, direct reading sound velocity, PRT temperature and MEMS based inclinometer.
ROVNav 6 is fully compatible with Sonardyne’s modem and logging equipment such as AMT and Fetch products, allowing it to be used to retrieve data or configure logging regimes. It supports all of Sonardyne’s Wideband® 2 spread spectrum acoustic communication; 100, 200, 400 and 900bps user data rates can be selected depending on the environment.
In addition, via a separate connector on the ROVNav 6, there is a power and communications interface to Sonardyne’s external Remote Sensor Pack ( Type 8311). Sensor options include a Digiquartz pressure sensor, precision inclinometer and altimeter interface. This provides a fully featured ROV manipulator deployable tool / sensor pack for a range of different applications including metrology, bathy survey and structure deployment operations, without the requirement for any additional interfacing on the ROV.
