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
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 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.
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 Technologies was established in October 2019 in Finland with the aim of becoming the leading provider of state of the art situational awareness systems and related autonomous navigation solutions and helping our customers to move to the forefront of maritime digitalization.
