Line 2: ==Method== A modulation depth comparison navigational aid (MDCNA), also known as an ~~''instrument~~[[Instrument_landing_system\|Instrument ~~landing~~Landing ~~system''~~System]], uses the concept of [[space modulation]] to provide guidance to aircraft when on final approach. A [[Carrier wave\|carrier]] and [[sideband]] (CSB), and [[Double-sideband suppressed-carrier transmission\|sideband only]] (SBO) signal, transmitted from [[Instrument landing system localizer\|localizer]] and [[Instrument landing system glide path\|glide path]] antennas produce a space-modulated signal resulting from the vectorial addition of two or more audio signals that vary according to position of the receiving aircraft.
