Containers stored temporarily by the use of visual means and are manually confirmed, lead to an error rate in the storage handling, compromising the efficient turnover time of the container ships. To counteract these implications, Differential Global Positioning Systems (DGPS) are used to avoid misplacement of container/s, help with equipment routing, and optimize dispatch of WI. It operates by sending lift and set down messages to the TOPX RTG (EC) application, enabling the automatic steering of particular vehicles and cranes, hence providing greater control and accuracy of the positioning and documentation of containers within the terminal.


DGPS is part of the Internet of Things transforming the way containers are handled in a terminal.

Why wait? Revolutionize your terminal now.

  • Picking a Container

    The system can verify if the correct container has been picked.

  • Placing a Container

    The system can verify if the container has been placed in the correct planned location, if not, it can commence a dialogue with the operation for exception handling.

  • Automatic Container Location Confirmation

    Does not rely on CHE operator confirming container location (which is often incorrect).

  • Automatically Records CHE Moves

    Extremely accurate since the DGPS instantly and automatically records when CHE operator completes a move.

  • Absolute Correct Container Locations

    Real-time instructions ensure containers are always placed in their most updated and correct position in the terminal yard. Otherwise, CHE will not release container and lock onto it until it is placed in the correct location.
