Sensor Solutions for Autonomy

Global leader of precise positioning and situational awareness sensors

Guidance Marine has built on its knowledge and experience to provide a series of sensor capabilities for autonomous and remote operations.

Our product family includes sensors that accurately measure both local and global position, provide situational awareness, hazard detection and capabilities for autodocking. Guidance Marine is constantly driving forward to develop new sensor technologies and capabilities. We positively encourage collaboration with our customers so that we develop products that really meet the requirements of what the end users want. As an example of our commitment to furthering autonomous vessel operations, Guidance Marine is part of the Wärtsilä IntelliTug project which utilizes a number of Guidance Marine’s sensors.

Smart Sensors

Guidance Marine sensors are already integrated into some of the most complex navigation systems, however we do not believe that added complexity should be more demanding for the end user. Our systems are designed to be simple to use and are highly endorsed by ships captains and masters because of their easy to read displays and simple user interface.

Our sensor technologies can already be used as tools to assist manual operations to improve safety, accurate positioning, situational awareness and hazard detection. Additionally, all our sensors provide outputs to enable them to integrate seamlessly into the ship’s navigation systems, whether that be for automating manoeuvres, enabling remote control or for a completely autonomous system.

A Guidance Marine designed system is more than just a sensor. It is a practical, well-engineered sophisticated system offering precision, reliability and confidence to the end user, whether they are on the vessel, on a nearby shore or even on a different continent.

Product Descriptions

CyScan AS | Using low power laser technology, CyScan AS provides precise local positioning (range, bearing, heading) when paired with one or more prism reflectors located around the harbour quayside. It can be used in GPS denied areas to allow vessels to manoeuvre in tight channels with cm precision. The range of up to 2.5km also allows for long distance precise approaches.

CyScan GeoLock | As the vessel approaches a harbour or port, the global location is identified by the GPS signal. This wakes up the CyScan AS which locks on automatically to a known constellation of reflector prism targets located in and around the harbour. The system provides global positioning using the GPS signal and is combined with CyScan AS for cm precision. After the CyScan has locked on to the targets, it can mimic a GPS signal, so if the GPS signal is lost after initial lock, the system can continue to provide ultra-accurate GPS location data. Range is up to 2.5km, so can be used on long range approach to GPS denied canyons and fjords.

RS24 | An ultra-high resolution, low power short range 24GHz radar that can fill in the close-range gap that is invisible to the traditional navigation radar system. The output from the sensor can be displayed directly on existing radar screens and complete the short range requirements for situational awareness within 1.5km range. Objects, including man over board, canoes and floating obstructions, can be detected. The high resolution and sharpness of image means that even in a busy harbour, the smallest vessels can be uniquely identified.

RadaScan View | Similar to RS24, this provides situational awareness with a 9GHz spinning radar, but also provides precise local positioning (range and bearing) when paired with a powered responder which is be located on the quayside. With a range of 600m, RadaScan View can be used in all weathers, including heavy rain, snow and fog.

RangeGuard | A 24GHz fixed radar sensor that measures the distance to the nearest object in its field of view (110 x 11 degrees). One or more sensors can be used to create a 300m virtual bumper around a vessel. RangeGuard can resolve two objects that are separated by as little as 0.75m. It can raise alarms if an approaching object breeches a distance limit. It can also be used to precisely measure the distance to other vessels or the quayside.

SmartQuay | Based on camera technology, SmartQuay projects a calibrated measurement grid onto a real-time video image of the quay during the docking manoeuvre. This is displayed on the bridge and provides an indication of the gap measurement between the vessel hull and the quayside.

Guidance Marine have already made steps towards autonomy and are featured in Wärtsilä’s IntelliTug project, which combines technologies, innovations, and digital solutions to develop a tug with autonomous navigation. The concept is aimed at having a vessel capable of performing a range of routine missions designed to further improve operational safety and efficiencies for tugs.

The Wärtsilä IntelliTug Project

The first project to be co-produced at the Wärtsilä Acceleration Centre is the Wärtsilä IntelliTug. By partnering with PSA Marine and MPA, Wärtsilä has embarked on a venture to enhance the capabilities of the harbour tug.

With more than 90,000 towage jobs in each year, the PSA Marine tug operations are an important lifeline for Singapore. To meet the demands of the evolving port, the collective is collaborating to bring to life a smarter tug that will perform a range of routine missions designed to further improve tug safety and efficiencies, while reducing operator workload and pressures in one of the world’s most demanding harbour environments.
