RTK-GNSS-based pile driving barge positioning guidance system
1. Guidance for Pile Driving Barges using RTK-GNSS ▻ Install GNSS antennas at two locations on the pile driving barge to measure the position and orientation of the barge in real-time. ▻ Display necessary guidance information on the screen of the guidance PC installed in the control room, using both numerical data and diagrams. ▻ Can be retrofitted to any type of barge. 2. Guidance for Pile Driving ▻ Display the guiding position of the barge, the current position of the barge, and the designed pile installation position in the site coordinate system. ▻ Enable guidance for the center position of the crane on the barge, the leader position, and the pile keeper position. ▻ As an option, add a crane inclinometer and a rotation meter to enable guidance for the tip position of the crane.

Applications/Examples of results
Typically, it is necessary to conduct surveys for pile driving from a different location, but by using this system, it becomes possible for the barge to independently guide itself to the target position, speeding up the construction process. Not only can the position for pile driving be confirmed, but the orientation of the vessel can also be checked, allowing for accurate construction.
