AN APPROACH TO THE DEVELOPMENT OF VIRTUAL DGPS NETWORKS

This paper represents an approach for developing of a virtual reference systems network (Virtual DGPS Network) for the needs of the maritime navigation. The current status of DGPS coverage over the Mediterranean – Black Sea region is analyzed. The use of the data generated by the suggested model increases considerably the accuracy of GPS measurements, thus satisfying the requirements of the International Maritime Organization (IMO) and the requirements of the US Department of Defense and US Department of Transportation “2001 Federal Radionavigation Systems” (FRS).
