Glossary » TACAN


TACAN is a tactical air navigation system used by military aircraft. It provides the user with bearing and distance (slant-range) to a ground or ship-borne station. It is a more accurate version of the VOR/DME system that provides bearing and range information for civil aviation.

Theoretically a TACAN should provide a ninefold increase in accuracy compared to a VOR. TACAN stations can provide distance up to 390NM.
