The self-propelled construction
machine I according to the invention has a DGNSS rover unit 14 for receiving
satellite signals from a global navigation
satellite system and correction signals from a reference
station 15 to be set up in the vicinity of the self-propelled construction
machine. The DGNSS rover unit 14 comprises a
processing and evaluation unit 18, which is configured such that, based on the
satellite signals and the correction signals from the reference
station, construction
machine position data describing the position of a construction machine reference point R on the construction machine is determined. The
processing and evaluation unit 18 is further configured such that, for a reference
station position data
record stored in a reference station position
data memory 23, at least one machine-readable data
record, in particular a QR code, is generated, which is displayed on a display 8A.The QR code can be scanned with a smartphone 26 equipped with a map service and
navigation function, making it easy to locate the installation point for a reference station in the field. Alternatively, the data can also be read using an NFC
receiver (NFC reader) based on RFID technology.
