Unrivalled stability, accuracy and results

Delivering unrivalled stability, position accuracy and results in real-time, Equinox is your integrated, towed multi aperture sonar with improved area coverage rates for mine countermeasures (MCM) and hydrographic operations.
At its core, is Solstice multiple aperture sonar (MAS) delivering imagery of the highest quality possible from side-scan sonar enabling detection and classification of seafloor objects across the whole swath.

Combined excellence

Overview

Equinox is a true example of how Covelya Group technologies combine to provide ground-breaking products. Designed around the Solstice MAS from Wavefront Systems, it is commercialised by Sonardyne and features our state-of-the-art SPRINT INS and Mini-Ranger 2 USBL for state-of-the-art navigation and positioning.

The Sonardyne and Wavefront Systems payloads are all mounted on EIVA’s renowned ScanFish 3D, a steerable remotely operated towed vehicle (ROTV). EIVA’s NaviSuite Kuda user interface is used to plan, autopilot and display the gathered data in real-time.

Producing stunningly accurate pictures, it’s ideal for vessels of opportunity or unmanned surface vessels delivering hydrographic, archaeological, search, salvage, unexploded ordnance, and mine countermeasure missions.

Why Equinox is perfect for your operations

The ScanFish 3D is a trusted ROTV and, thanks to its inherent stability, the ideal platform to operate Solstice from. At a total weight of 220 kg in air, Equinox can be easily mobilised.

Unlike towed Synthetic Aperture Sonar (SAS) systems, Equinox offers you an affordable, lower-logistics alternative still capable of providing high area coverage rates. By combining leading navigation and positioning from Mini-Ranger 2 USBL and SPRINT INS, imaging data is geo-referenced with an accuracy that’s unrivalled for these types of applications at this price.

Planning a mission is easy. Using NaviSuite Kuda software, you can define your sailing route and run-lines by simply selecting the area you would like to cover. During the mission, NaviSuite Kuda continuously updates the vessel and ScanFish 3D position in real-time.

Equinox also provides real-time geo-rectified waterfall, mosaics and DTM maps and the user interface tools that enable an operator to mark and process objects, including automatic target recognition using AI.

That’s not all; ScanFish 3D can carry heavier payloads and there is room in the fibre cable to include additional payload sensors such as gap fillers. Equinox users can count on improved probability of detection and decreased probability of false alarms, improving the efficiency of your mine countermeasures, archaeological, search and salvage missions.

The system provides high-performance coverage with large 200m swaths on each side, enabling efficient site characterisation without sacrificing detail. Its class-leading imagery allows you to make confident classification decisions more quickly, with the added versatility of deployment on both autonomous underwater vehicles (AUVs) and towfish platforms. By improving probability of detection and decreasing false alarms, Solstice significantly increases the overall efficiency and reliability of underwater exploration and survey missions. It is suitable for:

 

  • Autonomous underwater vehicles (AUV)
  • Site survey and characterisation
  • Mine countermeasures (MCM)
  • Remotely operated vehicles (ROV)
  • Delivering pixel perfect imaging

Exceptional high-contrast seafloor imagery across diverse water depths

How it works

Solstice, designed by Wavefront Systems and commercialised by Sonardyne, is a world-leading side scan sonar for autonomous underwater vehicles (AUVs) and towed bodies. Its advanced technology delivers exceptional seafloor imagery through multiple aperture arrays with 32 multibeam elements, enabling superior signal-to-noise ratio performance and stunning imagery at extended ranges. The sonar’s unique back-projection beam-forming technique ensures focused imaging for every pixel, eliminating distortions caused by platform motion and guaranteeing 100% ground coverage across diverse water depths.

Designed for a wide range of marine missions including hydrographic, archaeological, search, salvage, and mine countermeasure operations, Solstice stands out through its innovative features. Its real-time array calibration dynamically recalibrates hydrophone elements multiple times per second, compensating for dynamic strains and maintaining linear element alignment. The system produces high-contrast imagery in environments ranging from 600-metre depths to very shallow littoral waters, utilising a specialised array technology that provides wide swath coverage with exceptional shadow contrast.

Overview

Efficient, secure, safe

Underwater mine clearance operations put your people, assets and missions at risk. Our Initiation Transponder 6 (IT 6) helps mitigate this risk; enabling mine neutralisers to be efficiently, securely and wirelessly activated from a safe distance. Suitable for a range of scenarios, from military diving, explosive ordnance disposal (EOD), ROVs, MCM and site survey and characterisation

Secure and reliable

When safety is paramount in your survey and clearance operations, IT 6 offers a solution to ensure your success.

For energy: With any offshore energy development, there’s the potential to encounter unexploded ordnance (UXO). IT 6 improves the safety and efficiency of clearance operations, keeping your personnel away from risk and your project on track.

For defence: An important new addition to the MCM and underwater ordnance playbook, IT 6 helps your clearance divers and robotic platforms dispose of modern day and historical ordnance, quickly and effectively.

IT 6 is based on our field-proven Wideband 2 digital signal technology, which offers a reliable and long-range underwater wireless communications link. With IT 6, your personnel no longer need to hard wire mine neutralisers up to signal relay buoys on the surface and can set up an initiation operation in bad weather and outside of daylight hours.

Initiation Transponder 6 (IT 6) is designed to be connected directly to a remotely deployed, non-electric (NONEL) mine neutralisation device, such as a Viper from ECS Special Projects. This allows commercial and naval EOD teams to send a wireless, acoustic command from their vessel to initiate a shock tube.

It can be placed directly by a clearance diver or remotely operated vehicles (ROV). Divers and ROVs are constrained by the equipment and payload they can carry so we’ve designed IT 6 to be small and lightweight yet tough enough to withstand everyday operational situations.

With use cases from offshore renewable energy to government and defence, IT 6 transponders are suitable for high order detonation and low order deflagration scenarios.

At a glance:

  • Efficient, secure, safe
  • 357 mm tall by 55 mm in diameter; 0.10 kg weight in water; designed to be carried by clearance divers or small ROVs
  • Controlled using IP67-rated Deck Topside and cabled acoustic dunker
  • Safe: automatic time-outs, hydrostatic switch, independent circuits for acoustics and firing
  • Built using 6G hardware and Wideband 2 digital signal architecture: track with our Ranger 2 family of USBL tracking systems

The complete solution

Built for your UXO, MCM and EOD missions

Wireless

Underwater acoustic command and control is in our DNA, so IT 6 can be considered as reliable and as secure as traditional methods involving shock tubes and a lot safer than electrical detonation lines.

Safe

Safety and simplicity are key with the IT 6 and it features several fixed and user-configurable safety features.

Firstly, the IT 6 comes complete with a hydrostatic switch, which means the unit cannot be put into an armed state when shallower than the fixed hydrostatic switch depth. If recovered back to deck, the IT 6 will also render itself impossible to arm when it goes below the minimum allowed depth.

Configurable off-deck delays and seabed timeouts mean fixed arming and firing windows can be set. The internal circuitry of the IT 6 also means that no power is applied to the independent detonation circuitry until the operator chooses to fire/initiate the NONEL output from the IT 6.

The clear housing on the IT 6 contains three status LEDs which allow the operator to quickly assess the state of the transponder and its safety. A magnetic ‘remove before use’ pin also means the IT 6 has a long operational battery life and can be powered down completely when not in use.

IT 6 is controlled using our field-proven Deck Topside system. Environmentally rated to IP67, the topside features a daylight readable 7-inch resistive touch screen, physical initiate/arm buttons and rechargeable battery – perfect for operating from small craft with no external power.

A further operational benefit of IT 6 is that its location can be tracked using any our Ranger 2 USBL systems which are installed on hundreds of energy, defence and science vessels globally.
