Summary
TACAN (Tactical Air Navigation) is an ultra-high frequency (UHF) radio navigation system
Description
TACAN (Tactical Air Navigation) is an ultra-high frequency (UHF) radio navigation system used primarily by military aircraft to determine their bearing (azimuth) and slant-range distance relative to a ground-based or ship-borne station. It serves as a more compact, rugged, and accurate military counterpart to the civilian VOR/DME navigation framework.
