An instrument landing system (ILS) is described. The ILS comprises a plurality of antennas and a plurality of antenna radio units (ARUs). Each ARU of the plurality of ARUs operates to generate a modulated RF signal provided to a different one of the plurality of antennas for transmission. The ILS further comprises a central processing unit that operates to control the ARUs to adjust synchronization between the modulated RF signal provided by the ARUs to the plurality of antennas for transmission.
