Vigilant FLS
for Crewed Surface

Vigilant FLS – Explore with confidence.

See Vigilant in action

Are you navigating your vessel in poorly charted waters or regions prone to debris or ice flows? Or perhaps you’re exploring regions within the habitats of large marine mammals?

Our Vigilant Forward Looking Sonar (FLS) will transform your underwater situational awareness.

You will be alerted automatically to underwater collision threats like containers or mega-fauna as well as to grounding obstructions such as uncharted reefs or sand banks – giving you that precious time to take necessary evasive action.

Benefits of Vigilant for your operations

Integration

Unrivalled resolution and detail that’s compatible with your existing bridge system, with the added benefit can be retrofitted to any vessel.

Technology

Unique patented technology capable of depth finding at ranges ahead of your vessel in excess of 20 times the prevailing water depth.

Safety

Pushing the boundaries can take you to uncharted waters. Navigate and keep your vessel safe even in harsh polar regions.

Vigilant FLS Overview

Vigilant provides real-time 3D images of the seabed and water column ahead of your vessel. It maintains a history of the entire seabed environment around you. Not only will you know what is ahead of you but Vigilant will also provide automated warnings and cautions to prevent collisions. Hazards are no longer hidden from sight.

Vigilant is our family of long-range, Forward Looking Sonars (FLS). They are compact navigation and obstacle avoidance sonars providing automated alarms warning of objects in the water column out to 1.5 km. They create – with unrivalled resolution and detail – a real-time, easy to interpret 3D terrain map of the seabed and water column ahead, out to 600 m, and down to 100 m water depth.

Fit them to your vessel and you’ll be prepared for anything. Seek out a secluded bay, navigate busy shipping lanes or voyage into the Arctic Circle to watch the Northern Lights with confidence.

The Vigilant 1000 and 1500 models consist of a separate sonar projector and receiver array mounted in the vessel bow, either in the bulb, alongside in a tube or on a retractable deployment pole. Vigilant 600 features a combined projector/receiver design for applications where space is limited. In addition, we provide both processing software and hardware and optional bridge display and control hardware.

Vigilant systems are designed for installation in a wide range of vessels, from exploration cruises, private yachts and naval ships to harbour patrol vessels, offshore support vessels and research ships. Engineering support is available from our dedicated team and our experienced travelling engineers can commission and set up the systems onboard as required.

Vigilant has two principal operating modes: 3D and SONAR mode, both of which offer a class leading 120 degrees field of view on all range scales. Vigilant’s unique patented technology allows our 3D mode to provide stunning 3D depth imagery further ahead of the platform than any competing system, at ranges in excess of 20 times the prevailing water depth up to a maximum 600 m range and down to 100 m depth. Sonar mode processes the intensity of the acoustic data to extract long-range positional data of objects up to ranges of 1500 m. Data from both modes are used to automatically generate alerts for the operator or supervising system to warn of the presence of a navigationally relevant obstacle. With its history mapping capability, a comprehensive picture of the underwater environment surrounding the vessel is built up. This provides crews and autonomous systems with maximum situational awareness for collision or ground avoidance, tight manoeuvres or backing out of confined areas.

The Vigilant FLS family are designed to be retrofitted to existing vessels and new builds. Comprehensive engineering support and advice is available from Wavefront to support installation and commissioning.
