…with TACAN) installation allows both military and civil aircraft access to 2D positioning. Low-power DME transponders are also associated with some instrument landing system (ILS), ILS localizer and microwave landing system (MLS) installations. In those situations, the DME transponder frequency/pulse spacing is also paired…
View of the primary component of the ILS, the localizer, which provides lateral guidance. The transmitter and antenna are on the centerline at the opposite end of the runway from the approach threshold.
