Plita L. Models and methods for improving navigation safety based on a local radio navigation system with a flexible structure

The Maritime Doctrine of Ukraine for the period up to 2035 identifies priority areas for the development of river and maritime transport, its role in the state's economy and emphasizes that "the formation and implementation of effective state maritime policy will further strengthen Ukraine's position as a maritime state. goals and solutions for the development of maritime activities. " The research performed in her dissertation shows that the indicators of the quality of passenger and cargo transportation, the level of accident-free navigation continue to improve. Particular attention is paid to measures to ensure a given level of safety. A significant role in this direction is the effective solution of navigation tasks. This further emphasizes the relevance of research to improve the efficiency of sea and river vehicles through the use of operational and reliable navigational information. At present, advanced technological solutions based on satellite navigation are used to ensure a guaranteed level of reliability, accuracy and efficiency of navigation. Analysis of foreign and domestic experience in the development and implementation of navigation systems that use GNSS indicates the possibility of significantly increasing their efficiency through the development of mathematical software and the use of so-called local radio navigation systems. The most relevant in this direction is the use of local (pseudo-satellite) radio navigation systems that operate in the format of GNSS-signals with a variable or flexible structure. In such systems, radio navigation points are mobile, which allows you to quickly ensure the specified accuracy of navigation in a particular area of navigation.
