In this scheme, the missile would guide itself using onboard electronics and navigational signals received from the ground.

On the ground, radio transmitters would send navigational signals to missile interceptors heading for battle.

Also, in some installations local weather conditions were periodically broadcast in voice over the range frequency, preempting the navigational signals, but eventually this was done on the central fifth tower.
