In 1929, he moved to London, where he was invited to work on television guidance for defense applications, building prototypes of a camera for remotely guided aircraft for the British Air Ministry, and later adapting it for the Italian Navy. The solutions of the technology what Tihanyi depicted in his 1929 patent were so influential, that American UAV producing companies still used many of its ideas even half century later, until the mid 1980s.
Tihanyi's relocation to London in 1929 led to his involvement in television guidance systems for military purposes. He developed a camera system for remotely controlled aircraft, which was later used by the Italian Navy. His patent from that year had far-reaching consequences, influencing American UAV manufacturers for decades.
