Archibald Low was known as the "father of radio guidance systems" for his pioneering work on guided rockets and planes during the First World War. In 1917, he demonstrated a remote-controlled aircraft to the Royal Flying Corps and in the same year built the first wire-guided rocket. As head of the secret RFC experimental works at Feltham, A. M. Low was the first person to use radio control successfully on an aircraft, an "Aerial Target". It was "piloted" from the ground by future world aerial speed record holder Henry Segrave. Low's systems encoded the command transmissions as a countermeasure to prevent enemy intervention."The Dawn of the Drone" Steve Mills 2019 Casemate Publishers. Page 189 "In order further to safeguard against outside interference I may have a number of inertia wheels of variable speed, only one being correctly adjusted to pick up the timed signals and actuate the mechanism." By 1918 the secret D.C.B. Section of the Royal Navy's Signals School, Portsmouth under the command of Eric Robinson V.C. used a variant of the Aerial Target's radio control system to control from ‘mother’ aircraft different types of naval vessels including a submarine.UK National Archives ADM 1/8539/253 Capabilities of distantly controlled boats.
