Civil users of the NAVSTAR Global Positioning System (GPS) in Hungary are experiencing occasinal severe interference at the GPS signal frequency of 1575,42 MHz. As the application of the GPS technique spread rapidly in our country , radio frequency interference (RFI) should be considered a serious threat to widespread applications. The new geodetic control network (OGPSH) in Hungary is based on GPS measurements by which more than 1100 sites have been established. The paper reports the experiences gained during this work. Interference sources could be tracked to ground based telecom digital data transmissions which are operating mostly in Western part of Hungary. telecomminication regulations exceptionally allow such transmissions in specified countries. In order to warn potential GPS users mapping of the interference sources are being carried out.
