Improve area coverage rates for UXO (unexploded ordnance) surveys, MCM (mine-countermeasures) and hydrographic operations

Equinox is an integrated, towed multi-aperture sidescan sonar solution offering unrivalled stability, position accuracy and high-resolution, real-time results.

Combining EIVA’s ScanFish 3D remotely operated towed vehicle (ROTV) and NaviSuite Kuda survey software with Sonardyne’s SPRINT INS, Mini-Ranger 2 USBL and Wavefront’s Solstice multi-aperture sonar (MAS), Equinox is the perfect choice for UXO and site surveys pre-installation of renewable energy sites.

This integrated total solution leverages industry-leading commercial off-the-shelf components

The stable ScanFish ROTV platform tows the Equinox payload at a fixed height from the seabed, ensuring optimal performance of the Solstice multi-aperture sonar. This sonar not only delivers imagery of the highest quality possible from sidescan sonar, but also overcomes challenges typically associated with shallow water and high currents. Never miss any details again with crystal clear data swaths that grant you unrivalled imagery for your surveys.

In NaviSuite Kuda Pro + Processing survey software, this high-quality data is processed and visualised in real-time – ensuring actionable insights are at your fingertips. NaviSuite’s mission planning capabilities can improve survey area coverage though automated horizontal runline planning. Furthermore, you can choose an optional add-on NaviPac Pro licence to unlock a ScanFish autopilot flight mode: Vessel-Aided Follow Terrain, which uses a DTM, rather than the altimeter on your ScanFish, as input for creating real-time vertical runlines – achieving earlier warnings, thereby smoother obstacle avoidance and data collection.

Equinox offers several advantages, including that it…

  • Surveys more ground in a single pass; effective area coverage rate (ACR) of up to 1.6 km2/hour
  • Has an along track resolution of 0.15°; best in class delivering maximum detection rates
  • Improves your situational awareness by co-locating sidescan and bathymetry data display
  • Provides real-time motion compensation and positioning accuracies better than 1 m DRMS
  • Automatically follows terrain and avoids obstacles

Equinox is mission-ready for vessels or unmanned surface vessels (USV) delivering unexploded ordnance (UXO), archaeological, salvage, Search, Classify and Map (SCM) and hydrographic operations. The system can be configured  further based on your operation needs.

    Easy survey planning

    … by using NaviSuite Kuda software to define your sailing route and runlines – which is as simple as selecting the area you would like to survey

    Review data while it is being gathered (so it can be used in the next stage of the survey)

    … by monitoring NaviSuite Kuda’s real-time data displays during operations – the software continuously updates the vessel and ScanFish 3D position data, as well as processing and visualising Solstice data

    Visualise and analyse data

    … with real-time geo-rectified waterfalls, mosaics and DTM maps – as well as user interface tools to mark and process objects, including automatic target recognition (ATR) using AI

    Significant payload capacity

    … with the large capacity of the ScanFish ROTV, as well as room in the fibre cable to include additional payload sensors such as gap fillers

    Controlling the ROTV's movements in ScanFish III Fligh software

    Controlling the ROTV's movements in ScanFish III Flight software

    Only a minimum of training is required to prepare the crew to operate the ROTV, which means you will be ready to set sail within a short period of time. Moreover, there is no risk of wasting time on difficulties resulting from a complicated software user interface.

    Via the intuitive interface of ScanFish Flight, you are in complete control of the position of the ROTV by defining its height compared to the seabed. At the same time, you can monitor its position in the water, and an alert panel will warn you of any irregularities.

    On-site calibration

    A pre-flight feature allows for testing and calibration of the ScanFish ROTV on-site prior to deployment, promising you the highest possible performance and data quality.

    Recording of flight data

    Acquired ROTV data can be analysed by means of a flight recording feature. It enables you to play back all flights and, for example, quickly locate the cause of any irregularities, thus enhancing the quality of your results and saving survey time.

    Automatic control of winch

    ScanFish Flight can be set up to control the winch towing the ScanFish ROTV, thereby ensuring an optimal cable length adjusted to the movements of the ROTV. This is especially relevant for the ScanFish Konia and ScanFish Rocio models.

    Robust product with a long service life

    Quality materials and easily replaced wear parts characterise the ScanFish range and contribute to a high ROI through a long service life

    The practical design of the ScanFish models makes them so robust that they can be deployed in rough weather. This saves time as the risk of downtime is vastly reduced. Two side plates with bars, which also function as handles, protect the body and facilitate handling, thus reducing the risks posed to the ROTV in the water and ensuring the safety of the crew during deployment and recovery.

    Features enabling autonomous operations

    NaviSuite Kuda enables autonomous operations with tools to automate your survey every step of the way – from survey route planning to remote controlled, autopilot operations. Dive into how…

    Automatic survey route planning tools

    Ensure efficient coverage during surveys with tools for survey route planning. These intuitive tools help ensure your survey is performed optimally – through highly customisable and automated route planning.

    Onboard automatic route planning during surveys

    Conditions such as the weather can influence your coverage during a survey. In order to adapt to such factors, you can use the Coverage Assist tool, which plans runlines in real-time during the survey. Each time it creates a runline, it considers the previous surveyed line, as well as the optimal route for turning. This saves you time as it makes decisions onboard the vessel in real-time.

    Autopilot route planning by defining a boundary

    The vehicle route can be automatically created before a survey, based on a boundary. If your vessel has an NMEA autopilot, you can export route plans from NaviSuite to the onboard piloting system.

    You can design the lawn mower type pattern depending on the desired spacing and orientation. You can also create an exclusion zone within the boundary.

    To ensure centimetre precision line-keeping and safer operations, you can equip your vessel with the NaviSuite Kuda – Autopilot. This autopilot enables extensive USV control in NaviSuite Kuda, for example precise line-keeping in sharp turns and a hold position capability, as well as allowing you to monitor your thrusters and easily switch between manual and automated steering.

    Remote control from anywhere in the world

    NaviSuite software enables you to operate control systems from anywhere in the world. For example, L3HARRIS performed a harbour survey with a USV in the UK while the data control was streamed to Brazil.

    Remote control even at low bandwidth

    One of the challenges to remote control is low data bandwidth. With NaviSuite you can overcome this in several ways…

    Live data compression

    You can compress survey data in many ways to ensure uninterrupted signal. NaviSuite compression tools work on multi-beam echosounder, sidescan, laser and forward-looking sonar data.

    The settings you can adjust include Along, which allows you to skip scans. As well as Across, which reduces the points across the scan, and analyses points with respect to depth change to then keep more points where there are areas of change.

    Pre-plan autonomous underwater vehicle (AUV) operations

    NaviSuite lets you remotely control an AUV without requiring constant connection. You can send small mission updates to your AUV, requiring only one good link moment to input your instructions – for example to go at a certain depth, pitch and heading. This capability means that no matter if the connection fails, the AUV will follow the directions you input in your latest mission update.
