General conclusion of various sources from the non-Soviet literature and some practical data obtained as a result of observation of the operation of a 'LORAN-C' during the time period 1963-1965 are presented. In operation the pulse-phased system, by comparison with other systems, utilizes a more complicated method of transmission of long radio waves and more complicated shipboard equipment is necessary for obtaining a similar reading of the navigational data. This definitely makes it difficult to study the operation of the pulse-phased system. Therefore, the present work may help master the basic operating principles of the pulse-phased system and correctly evaluate the technical and navigational possibilities of the LORAN-C radio navigation system. (Author).

This book systematically presents the operating principles and technical characteristics of the main radio navigating systems (RNSs) that make it possible to adequately evaluate the corresponding scratch indexes and levels of air safety for air vehicles, the chief concern of the International Civil Aviation Organization (ICAO). The book discusses how RNS systems substantially determine navigation accuracy and reliability, and therefore air safety; in addition, it presents practical solutions to problems arising in the operation and development of RNS systems.
