Reference station setup point

A method of establishing a reference station setup point for setting up, in a vicinity of a self-propelled construction machine moving on a site, a reference station that transmits correction signals to a DGNSS rover unit associated with the self-propelled construction machine, the DGNSS rover unit determining, on the basis of satellite signals of a global navigation satellite system and correction signals of a previous reference station already set up on the site at another setup point in the vicinity of the construction machine, position data describing the position of a construction machine reference point on the construction machine in a coordinate system independent of the construction machine, the method comprising:

• moving the construction machine to a waypoint on site, in the vicinity of which the reference station is to be set up, and determining position data describing the position of the construction machine reference point on the construction machine in the coordinate system independent of the construction machine using the DGNSS rover unit at the waypoint, on the basis of the satellite signals of the global navigation satellite system and the correction signals of the reference station already set up on site in the vicinity of the construction machine;
• establishing a point on a ground surface that is in a specified spatial relationship to the construction machine reference point on the construction machine as the reference station setup point at which the reference station is to be set up;
• determining position data describing the position of the reference station setup point in the coordinate system independent of the construction machine on the basis of the position data describing the position of the construction machine reference point on the construction machine at the waypoint and on the basis of the specified spatial relationship between the construction machine reference point on the construction machine and the point established as the reference station setup point on the ground surface;
• and
• storing the position data describing the position of the reference station setup point in a storage unit.

A position determination system for determining a position of a construction machine reference point on a self-propelled construction machine in a coordinate system independent of the construction machine, comprising:

• a reference station configured to transmit correction signals calculated on a basis of an actual reference station position and a reference station position determined by the reference station;
• a DGNSS rover unit configured to receive satellite signals of a global navigation satellite system and the correction signals from the reference station, the DGNSS rover unit being configured such that, on the basis of the satellite signals and the correction signals, position data describing a position of a construction machine reference point on the construction machine are determined in the coordinate system independent of the construction machine;
• and
• a reference station setup point establishing device configured such that a point on a ground surface which is in a specified spatial relationship to the construction machine reference point on the construction machine can be established as a reference station setup point.
