Development of automatic G/T measurement program for THAICHOTE ground station

A figure of merit for operating earth stations can be evaluated by G/T measurement. The performance of receiver must be retained quality for handling a weak power. Currently, the development of new S-band antenna system for THAICHOTE satellite series is being performed by GISTDA so that G/T measurement program is also required to be one of that parts. Particularly, this program attempts to be automatic function by starting from the sun tracking to G/T solution. This paper will describe the methodology and assessment of accuracy by referring to the original system.
