IXSEA has won a contract from the French based submarine cable installation company, LD TravOcean for a GAPS USBL. The portable and calibration free Global Acoustic Positioning System (GAPS) combines USBL, INS and GPS technologies. It works both in deep or extremely shallow water. After a number of trials in extreme environments, such as very shallow water, GAPS remained fully operational.   (read more)

TrackLink USBL Systems

LinkQuest Inc. has received an order from Nekton Research LLC of Durham, North Carolina for a TrackLink 1500MA system with integrated two-way acoustic communication capability. This system will be used to track the AUV (manufactured by Nekton) while the operator performs command and control of the vehicle. The tracking system is required to work reliably in a 150 x 100m quarry, where the acoustic signal is highly reverberated due to rock walls and bottom. The order followed on successful specification tests. MacArtney A/S of Denmark has also ordered a LinkQuest system to be installed on a client's Seaeye Falcon ROV.... (read more)

Guidelines for Vessel USBL

The publication Guidance on Vessel USBL Systems for Use in Offshore Survey and Positioning Operations (IMCA S 017) is intended for use by offshore construction, survey and inspection companies when chartering third-party vessels with USBL system(s) already installed, when commissioning new USBL installations on new-build or existing vessels, or when maintaining existing systems.       Advances in system design and sensor performance, together with high-accuracy GNSS surface positioning, have led to a significant increase in the capability, performance and accuracy of modern ultra-short baseline (USBL) acoustic positioning solutions. This has made it possible for such solutions to be used... (read more)

Subsonus USBL Released

Advanced Navigation has released the Subsonus USBL underwater acoustic positioning system. This is a next-generation USBL underwater acoustic positioning system that, according to the manufacturer, provides high-accuracy position, velocity and heading at depths of up to 1,000 metres. The system features a hydrophone array combined with an internal tightly coupled INS, all packed into a miniature titanium enclosure small enough to fit in the palm of the hand. Subsonus is currently undergoing final in-field testing and will start shipping to customers in Q2 2015. Subsonus features an eight channel calibrated hydrophone array, offering angular and ranging accuracy. Subsonus's hydrophones are... (read more)

USBL for Noisy Waters

iXBlue (France) has sold two GAPS pre-calibrated USBL systems and a PHINS 6000 inertial navigation system to Ashtead Technology (UK). GAPS (Global Acoustic Positioning System) is designed for high-accuracy tracking of ROVs, AUVs, divers and sonar or other towed systems. It can be used in a wide range of water depths, but performs particularly well in shallow, acoustically noisy waters.    The units have their own internal inertial navigation system, which is pre-calibrated with the USBL before delivery to clients. This removes the need for a USBL calibration every time the system is mobilised.   PHINS 6000 is a subsea... (read more)

USBL System for Mexican Market

C&C Technologies, headquartered in the USA, has purchased the iXBlue fourth-generation GAPS USBL acoustic positioning system for the company‚Äôs Mexico division. This will be the first time the system is directly available to customers in Mexico. The system will be used to track subsea systems in shallow and deep waters in the Gulf of Mexico and to support a range of other subsea applications such as ROVs, subsea equipment placement and diver operations.   As part of the formal qualification programme, C&C staff put the new GAPS system through a number of challenging test scenarios, enabling C&C Technologies to track and...

USBL for Tidal Energy Positioning

One of the latest renewable energy sources currently being investigated for future large scale commercial deployment is tidal energy that exploits the natural ebb and flow of coastal tidal waters. As with other energy sources offshore, innovations to harness tidal forces often throw up additional operational difficulties particularly to do with positioning of the devices on the ocean floor and their connections to shore. Triscom have recently added the latest USBL positioning system, the Applied Acoustics' Easytrak Nexus, to its equipment pool to meet the increasing requirement for accurate underwater positioning tasks. Triscom is experienced in hydrographic/seabed survey and is... (read more)
