Case Study: RealTrac GNSS Positioning System on a Mining Vessel

Task

In offshore crushed stone extraction, the main problems were:

The vessel operates in waters without stable communication networks.
The crew could not accurately determine the vessel's position during extraction.
There was no tool to record in which grid square and in what volume extraction had already been carried out.

This created a risk of mining the same area twice and reduced extraction efficiency.

RealTrac implemented a positioning system based on vehicle tags and a local server:

A RealTrac vehicle tag with GNSS technology was installed on the vessel.
A RealTrac system server was also installed on board; it receives and processes data without connecting to external networks.
In the system interface, the crew sees:
- the current position of the vessel on the map;
- extraction coordinates linked to the grid squares of the water area;
- the movement history and the areas already worked.

The crew controls extraction in real time and avoids passing over already worked areas again.
Productivity increased thanks to optimized routes and accurate area records.
The system is fully autonomous and does not depend on external communication infrastructure.

Repeated work in already mined grid squares has been eliminated.

Data is recorded in the system and available for analysis.

The whole system runs on board without external communication channels.
