With the goal of supporting the preliminary inspection work at the relay site, TBS Television developed "ΩFINDER 'OMEGA FINDER'", the android application that operated at the mobile terminal. It was highly evaluated in Japan and abroad. In this lecture, while incorporating the concrete examples being used, I will explain the development of the "OMEGA FINDER" and what constituted the foundation of its development, the "FPU ANTENNA NAVIGATOR". I will also explain the development of the related equipment and the system that were implemented at the time of the renewal of the 4FSK system of radio communication for the use of broadcasting. Introducing these improvements of adjusting FPU antenna direction, carried out recently by TBS television, we also explain the back side of "OMEGA FINDER" development.
