The founders of Groke have a long background in maritime industry. Over the years they were able to recognize the challenges crews face while keeping look 24/7: poor visibility, stressful environment and inadequate situational overview of the surroundings. This can result as a fatigued crew, close-call-situations and collisions. Groke Pro was developed to provide a solution.
Groke Pro is a digital watchkeeper. It reduces crew stress and frees crew from watchkeeping to spend more time on important tasks. The day and night cameras combined with machine vision technology oversee the vessel surroundings 24/7 even in the most demanding conditions.
Not designed to replace existing systems like radars and AIS but to complement them, Groke Pro combines data from its two cameras and all existing systems on the vessel, and provides a real-time risk analysis to further support crew’s decision-making. All information is presented on the best User Interface in the market enabling easier and more efficient decision-making and communication among crew.
Groke Pro is a situation awareness solution that utilises different sensor inputs and fuses the information from them together.
As outcome the user gets analyzed situation overview on what is happening around the vessel.
Through our intelligent Groke Pro solution we aim to provide peace of mind , even in the most challenging conditions.
Groke Pro - Because We Care
Due to the overwhelming amount of information, decision-making in difficult conditions can be stressful. The intelligent risk analysis takes all the information collected, parses it and presents the crew with the most crucial information for better decision-making. Risk analysis consists of three elements: CPA Points & Alarms, Risk Compass and Relative Velocity Tracking.

Groke Pros intuitive tablet-based user interface provides the best User Experience in the market. You can easily inspect the detected vessels shown in the Augmented Reality (AR) view. Other features, such as the blending function and real-time risk analysis, are easily available in on display.
Learn MoreWachkeeping at night can put a lot of stress on the crew causing fatigue. Groke Pro features two cameras: a day camera and a thermal night camera. Grokes unique blending functionality enables combining views from each camera. As a result, at night-time, you get a view with lights from the day camera and the objects detected with the thermal camera. Users can easily adjust the level of blending emphasizing either the day or night camera.

The main component in Groke Pro is the sensor unit. It's specifically engineered for maritime environment by Groke Technologies. The unit integrates sensors such as double GNSS, IMU and AIS receiver. The unit also houses the two cameras of Groke Pro: a regular camera and a thermal night camera.
Central Unit is the heart of the system. It has the needed computing power for sensor fusion, object detection and classification models. It is built according to maritime engineering standards and uses marine type approved components where possible.
Groke Pro's user interace offers the best user experience in the market. As a standard option, Groke Pro is delivered with a tablet based user interaface utilizing iPad Pro tablet. 27" fixed display is available as an option. Groke Pro supports up to three displays.
The main component in our system is the sensor unit. The unit is specifically engineered and made for maritime situation awareness use by Groke Technologies. Unit includes integrated sensors such as double GNSS, inertial measurement unit, AIS receiver and most important are the two camera entities, one with 225 degrees field of view with day camera and the other with 180 degrees field of view with thermal camera.
Central Unit is the heart of the system, it hosts the computing power of sensor fusion and our object detection and classification models. It is built according to maritime engineering standards and uses marine type approved components where possible.
User interface is the pinnacle element of Groke Pro system for the user. As standard with Groke Pro solution we deliver tablet based user interface utilizing iPad Pro tablet. Customer can also choose to use our 27" fixed display which we offer as additional option to our system.
In one Groke Pro system we can supporting utilisation of up to three user interface devices.
Groke Technologies awareness system collects information from multiple sources. The difference of the developed system towards as systems today are presented in the diagram below. For visual confirmation, the system uses a wide field of view cameras with day and night vision. Object detection happens by utilizing machine vision for day and thermal camera images. Additional information about other objects is received from radar (optional add-on integration) and AIS. To identify your own vessel position and movements GNSS and Inertial Measurement Units (IMU) are used. Sea charts identify the vessel’s geolocation position.
Sensor fusion is the probabilistic mix of data from multiple sources such as described above.
Groke’s forte lies in combining all the above-mentioned via sensor fusion and track fusion offering. This offers both onshore and offshore users the most accurate and reliable understanding of their surroundings via a single view user interface. This results in reduced navigation stress and peace of mind during the operation in all kinds of conditions, regardless of vessel type.
Groke’s awareness system, Groke Pro, puts all the information in one single UI, giving an accurate and reliable picture of nearby vessels’ location, speed, and trajectories and other objects that can be taught for the system utilizing AI.
As mentioned above, the users of the system enjoy a unique user interface, providing only relevant information to help navigation and watchkeeping.
Groke Pro installation onboard is straight forward and due to the stand alone nature of the standard solution it is ideal as retrofit to existing vessels and also to new buildings.
Preferred installation location for sensor unit on tug boats is either mast or on compass deck above bridge. The central unit shall be installed in close vicinity to bridge into an air conditioned or well ventilated space.
Preferred installation location for sensor unit on tankers is in non-EX/ATEX locations meaning either mast or on compass deck above bridge. The central unit shall be installed in close vicinity to bridge into an air conditioned or well ventilated space.
Preferred installation location for sensor unit on cargo vessels is either mast or on compass deck above bridge. The central unit shall be installed in close vicinity to bridge into an air conditioned or well ventilated space.
Preferred installation location for sensor unit on large and ultra large vessels is either mast or on compass deck above birdge. On larger vessels there is also the possibility of installing the sensor unit to fore mast but this needs to reviewed case by case. The central unit shall be installed in close vicinity to bridge into an air conditioned or well ventilated space.
