BCQ is a VORTAC, a combined VOR and TACAN transmitter. VOR, short for VHF Omni-directional Radio Range, is a type of radio navigation system for aircraft. VORs broadcast a VHF radio composite signal including the station's morse code identifier (and sometimes a voice identifier), and data that allows the airborne receiving equipment to derive a magnetic bearing from the station to the aircraft (direction from the VOR station in relation to the Earth's magnetic North at the time of installation).

TACtical Air Navigation, or TACAN, is a navigation system used by military aircraft. It provides the user with a distance and bearing from a ground station. It is a more accurate version of the VHF omnidirectional range / Distance Measuring Equipment (VOR/DME) system that provides range and bearing information for civil aviation. At VORTAC facilities, the DME portion of the TACAN system is available for civil use.
