I was going through some FAA course material on Instument Landing Systems
and the term SPACE MODULATION was mentioned several times. What the heck

this.

I believe this was fully explained in a documentary I saw as a kid.
Something about the Q-36 Explosive Space Modulator.

Was this Marvin the Martian?

Anyway I found that there truly is no such thing as space modulation. It is
used to form a concept of how ILS beam patterns are formed and all
modulation takes place in the receiver of the aircrafts ILS receiver. A few
years ago The FAA dropped this as a way of teaching ILS concepts.
