The subject of study in the article are the processes in oscillatory systems based on microstrip and symmetric strip transmission lines. The aim of the article is to develop effective means of eliminating interference generated by satellite radio navigation systems, which will ensure the possibility of functioning of the equipment of the EGNOS RIMS system in Ukraine. The problem to be solved is substantiation of technical solutions and analysis of the radio frequency environment as a key criterion for choosing the location of the EGNOS RIMS system in Ukraine and the impact of the radio frequency environ ment on the system performance. The article considers: there are interference sources in the deployment zone of the system, which negatively affect the characteristics of the EGNOS RIMS receiver, as their power exceeds the required level in the used GPS frequency bands L1 and L2. Features of resonator synthesis on closed and open segments of microstrip and symmetric strip transmission lines, to eliminate interference generated by satellite radio navigation systems. Promising ways of application of the offered resonators in the used frequency ranges of GPS L1 and L2. Conclusions: the proposed technical solutions should be used to eliminate obstacles that are formed in satellite radio navigation systems, providing the possibility of operation of the equipment of the EGNOS RIMS system in UkraineDownloads
