A more precise location of position can be attained through DGPS (Differential GPS). A reference station in Frankfurt/Main sends out a correction signal in real time over a long wave transmittor in RDS-Format. This correction signal is calculated and sent out every 3 seconds. This signal is, with the help of a DGPS receiver, only to be received in federal territory. Likewise, such facilities exist in Sweden and England. Through the operation of additional DGPS receivers, a GPS receiver can determine its position to 5 m. The long wave’s frequency range is high and experiences few topographical interference problems.
