Maritime operations in ports are very demanding in terms of navigation performance, that cannot be met by GNSS alone. It becomes crucial to fuse GNSS with other PNT sensors, in order to achieve the required performance levels to allow this kind of operations.
The use of GNSS alone is not enough for supporting berthing operations in ports. The influence of multipath and other factors doesn’t allow to achieve enough accuracy and reliability. In order to overcome this limitation, GSAB will integrate the fusion of several PNT sensors (GNSS receivers, IMUs, camera, radar, infrared cameras, etc.) onboard.
In addition, other system will be integrated, like AIS. In addition, additional sensors will be installed ashore (in the port), including a GNSS reference station and vision systems in the dock. Many ports cannot allow access to large ships, which number is rapidly increasing). GSAB system will support safer and faster manoeuvring and docking by allowing large ships access to these ports. This would result in a possible increase in traffic and the possibility of accepting Lines Operators that currently follow other routes, thus obtaining an increase in their commercial volume.
