Abstract

A method of automatically determining the position of vehicles by means of the DGPS (Differential Global Positioning System) is proposed, whereby at least one vehicle in the local public passenger traffic and one fixed station receive GPS data which characterize the distance to GPS satellites, where the data of the fixed station are transmitted as correction data 8 via service radio telegrams 5 to the mobile station 6 in the vehicles 1, and where the transmission of the correction data 8 takes place through expansion of the service radio telegrams 5 by at least one information byte 9.
