Claim 2:
3. A method for marking a ground surface according to a predefined marking pattern using a system comprising a robot unit and a local base station comprising acts of:
using a system reference point being an established system reference point according to the method of claim 1;
providing two flag points configured as physical points and/or as positioning data;
receiving global positioning data of the robot unit using a robot GNSS receiver;
receiving global positioning data of the local base station using a base GNSS receiver;
establishing flag point position for each flag point;
moving the robot unit according to a driving route for the robot unit comprising the predefined marking pattern;
calculating a current position of the robot unit using the received global positioning data of the robot unit, and
correcting moving direction of the robot unit according to the driving route using the calculated current position of the robot unit,, wherein
the predefined marking pattern is arranged relative to the two flag point positions;
the current position of the robot unit is calculated using the received global positioning data of the robot unit and position correction data from the local base station, and
the local base station communicates with the robot unit using a radio signal or a cellular data signal.
