According to IALA recommendations and ITU-R approval, a new frequency plan for DGPS reference stations in The European Maritime Area was initiated on 19th of September 2001. Radio broadcasting systems of two Polish DGPS reference stations: Rozewie and Dziwnow has been returned to new assigned frequencies. In result it caused a necessity to modify their signal coverages based on former measuring campaigns followed after the transmitting antennas were modernized (Rozewie in 1998 and Dziwnow in 2001). The article presents some results of DGPS signal strength simulation and actual measurements, as well as resulted, common DGPS RS coverage of both stations. Presented calculations were done on a base of the specialization software. For signal attenuation determination, a South Baltic Sea vector chart of the conductivity data was used. In result, the new values for Effective Radiated Power and nominal ranges were established.
