**Serdjo Kos**

Prof. Dr. Serdjo Kos is a Full Professor (tenured). For two terms, he was the Dean of the Faculty of Maritime Studies, University of Rijeka, and for four terms he was the Head of the Department of Nautical Science. Some of his scientific research interests include: the theories of loxodromic and orthodromic navigation; terrestrial, astronomical, and electronic navigation; satellite navigation, satellite and inertial navigation systems (ionospheric/tropospheric delay errors in GNSS systems, positional dispersion of accuracy in GNSS systems, satellite positioning errors due to extreme ionospheric and geomagnetic disturbances, GeoRSS systems and technologies, errors of inertial navigation systems, etc.); multimodal transport networks; intermodal/multimodal transport systems; optimization and simulation in maritime traffic; and risk assessment on the use of electronic navigation devices. Due to his significant scientific contribution to the theory of loxodromic navigation at the Royal Geographical Society in London, he received an international award from the British Royal Institute of Navigation; it should be emphasized that he is the only member of the Council of the Royal Institute of Navigation in London who is not a citizen of the crown countries of the Commonwealth.
