DGNSS – Differential Global Navigation Satellite System
Via pre-installed components, LIPOS® enables the direct integration of machine control systems from Trimble
or Leica in the process data recording PDE® and reporting of Liebherr deep foundation machines. Thesesystems are based on modern DGNSS technology (Differential Global Navigation Satellite System) and soachieve the best possible conditions for a precise and efficient positioning of Liebherr machines and their
attachment tools.

Further info

• Intelligent mounting bracket design for the antennae on the leader for optimum signal quality• Pinpoint precision of the drilling and piling work in accordance with a digital drilling plan
• Recording of the drilling points and work processes through the process data recording system PDE®
• Automatic transmission of the data to MyJobsite for visualisation and analysis• Generation of comprehensive and understandable jobsite reports
The positioning system LIPOS® is fully integrated in the existing IT solutions from Liebherr and compatible witha wide variety of deep foundation machines. The preparation for Trimble or Leica, as well as the machinebased complete system* from Trimble is obtainable from Liebherr.
