Part of Sonardyne’s Coastal Acoustic Product Range, the Type 7967 OBC/LRT Deck Unit is used to command and programme Sonardyne’s range of TZ/OBC transponders and Lightweight Release Transponders (LRTs).
It comprises of a deck unit and dunking transducer supplied with 10 metres of cable.
The deck unit is used initially to program the acoustic identity of the transponder, test the transponder and, in the case of the LRT, load the release ‘bit’ prior to deployment. Once deployed, it can be used to measure ranges to the transponder and prior to sending a secure release command, relocate the transponder.
The deck unit can also be controlled via RS232 enabling raw range data to be logged to a PC for processing.
SHALLOW WATER SUBSEA TARGET TRACKING SYSTEM
Scout USBL is a complete vessel based acoustic positioning system designed for tracking divers, ROVs and towfish in waters up to 1,000 metres.
The system calculates the position of a subsea target by measuring the range (distance) and bearing (heading) from a vessel mounted transceiver to a small acoustic transponder fitted to the target; a technique known as Ultra-Short BaseLine (USBL) positioning.
USBL is widely used by the offshore survey and ocean scientific industries as it offers high accuracy performance combined with efficient subsea tracking operations.
The Type 8026 Navigation Computer forms part of a Data Fusion Engine, a ‘one-box’ solution designed to meet the complete on-board requirements of any acoustic operation.
The Navigation Computer is a powerful, purpose-built computer that is used in conjunction with the Navigation Sensor Hub (NSH).
It has been specifically designed to run Sonardyne’s family LBL and USBL software applications.
Features include a front-mounted USB key port for when access to the rear of the unit is restricted by rack mounting or portable configurations.
UNDERWATER TRACKINGAND POSITIONING
TRACK EVERYTHING,IN ANY DEPTH, FROM ANY VESSEL. TRACK A TOWFISH, POSITION AN ROV, DP YOUR VESSEL, SEARCH THE SEABED OR NAVIGATE AN AUV.
WHEN YOU NEED TO INVEST IN ULTRA-SHORT BASELINE (USBL) ACOUSTIC TECHNOLOGY TO SUPPORT YOUR UNDERWATER OPERATIONS, RANGER 2 HAS THE PERFORMANCE YOU NEED, AT THE INVESTMENT LEVEL YOU CAN AFFORD TO GET THE PROJECT COMPLETED FASTER AND MORE EFFICIENTLY THAN ANY OTHER SYSTEM ON THE MARKET.
Mini-Ranger 2 is a sixth-generation (6G) Ultra-Short BaseUne (USBL) underwater target tracking system.
It offers a standard operating range of 995 metres (extendable up to 4,000 metres) and the ability to simultaneously track up to 10 subsea targets (e.g. divers, ROVs and structures) at very fast update rates.
These features mean that Mini-Ranger 2 is ideal for nearshore operations on small, quiet vessels, vessels of opportunity, pipelay and construction barges that need survey grade positioning performance without the cost and complexity of a deep water USBL solution.
USBL/LBL Transponder and Modem
The Type 8300 Midi Compatt 6 is a shorter length transponder based on the field proven mechanics of Compatt 6.
The design offers the user a lightweight unit with the same acoustic output power as a standard sized unit.
Its size is perfectly suited to acoustic metrology campaigns where the shorter length and optional integrated inclinometer reduces the lever arm and therefore errors for offsetting transducer to end cap.
Lodestar GyroUSBL combines a Sonardyne 6th (6G®) generation high performance HPT USBL transceiver and a Lodestar Attitude and Heading Reference System (AHRS) / Inertial Navigation System (INS) in the same mechanical assembly.
With the AHRS / INS in fixed mechanical alignment to the USBL’s acoustic array, the Lodestar GyroUSBL can be quickly deployed without need for a USBL calibration to determine the alignment of the ship’s motion sensors to the acoustic transceiver.
For certain applications, this can enable significant savings in vessel time and operational costs.
