PRELIMINARY REMARKS

The  software  MARPO_Dredger  is  part  of  the  MARPO_DGPS_K  extraction  monitoring
system.  It  is  able  to  display  and  save  positions  and  extraction  depths  of  the  excavation
tool of a dredger during the dredging process in a mining area.

This instruction manual describes the operation and function of MARPO_Dredger.
The different display options are explained by the help of screenshots.

The use of this software does not prevent wrong excavation processes…
