Current developments in Loran-C

Abstract

A survey is provided of the many new developments in the Loran-C radio navigation system in recent years; in system coverage, capabilities, and applications. These have come about as a result of new station installations and modern electronics. System techniques are reviewed and uqpdated, information on radio propagation is summarized, and micropcocessor-based receiver developments and solid-state ground transmitters are described. This has resulted in new applications of Loran-C to harbor navigation, civil aviation, and terrestrial uses, as well as extension of long-range capabilities, Extensive references are provided.
