(b) is used in connection with the determination of position, bearing or distance, or for the gaining of information as to the presence, absence, position or motion of any object or of any objects of any class,
and reference to stations for wireless telegraphy and apparatus for wireless telegraphy shall be construed as references to stations and apparatus for the emitting or receiving as aforesaid of such electro-magnetic energy as aforesaid:
Provided that where-
(i) a station or apparatus for wireless telegraphy cannot lawfully be used without a licence or could not lawfully be used without a licence but for regulations under this Act; and
(ii) any such electro-magnetic energy as aforesaid which is received by that station or apparatus serves for the conveying of messages, sound or visual images; and
