Abstract
A position determination system and a method are provided for determining the position of a reference point on a self-propelled construction machine in a coordinate system independent of the machine, and a method for initializing a reference station set up in the periphery of a self-propelled construction machine for sending correction signals. The position determination system comprises a DGPS rover unit for receiving satellite signals from a global navigation satellite system and correction signals from a reference station. For initializing the reference station, a position dataset describing the predetermined positions of a reference station is read out from a memory unit, wherein the actual reference station position is determined on the basis of a comparison of the predetermined positions of the reference station with the reference station position determined by the reference station.
