Kordil EPS – Excavator Positioning System
Kordil EPS is an excavator and dredger positioning system developed by Kordil. It provides real-time guidance to machine operators using GNSS sensors and onboard software with 2D, 3D, Difference View and profile displays. The system helps operators excavate, dredge, fill and grade to design levels without constant surveyor support. It supports productivity, reduces over-digging and helps save fuel and time while improving awareness near pipelines, structures and restricted areas.
Kordil EPS is used on excavators, dredgers, cranes and heavy construction machinery for marine, offshore and land projects.

Software screenshots and operator views
The Plan View offers three selectable display modes: the standard CAD model with colour marking, a 3D model view and the Difference Matrix. Operators can switch between these windows with a mouse click. The Profile View shows up to six design profiles together with one live survey profile.

The Difference Matrix indicates cut and fill performance against design levels. White represents the target result, red indicates high areas and the blue spectrum indicates low areas. The colours are adjustable by the user. The CAD display, marking, difference information, design model and survey model update dynamically during work.

Calibration and one-time setup
Sensor calibration and shape definitions can be carried out automatically through the system interface with one click, with manual calculations and adjustments available when required. A simplified 3D model of the vessel or machine is generated from basic shapes, avoiding the need for advanced 3D modelling. Remote recalibration support is available after machinery configuration changes.
