Abstract: A self-propelled construction machine includes a DGNSS rover unit including a computing and evaluation unit, configured such that, on the basis of satellite signals and correction signals of a reference station, construction machine position data describing the position of a construction machine reference point are determined. The computing and evaluation unit generates at least one machine-readable data set, in particular a QR code, which is shown on a display for a reference station position data set stored in a reference station position data memory device. The QR code can be scanned with a smartphone on which a map service with a navigation function is installed, so that the setup point on which a reference station is to be set up can be easily found on the site. In an alternative embodiment, the data can also be scanned using an NFC receiving unit (NFC reader) based upon RFID technology.

Abstract: A method for determining a reference station setup point for setting up a reference station includes moving a construction machine to a waypoint. At this waypoint, position data describing the position of a construction machine reference point on the construction machine are determined on the basis of the satellite signals of a global navigation satellite system and the correction signals of a reference station already set up on site in the vicinity of the earthmoving machine. The position data describing the position of the reference station setup point are determined based on the position data describing the position of the construction machine reference point on the construction machine at this waypoint and on the basis of a specified spatial relationship between the construction machine reference point and the point specified as the reference station setup point on the ground surface.
