Gain to noise temperature ratio software for S-band antenna.

Rancabungur S-band antenna is used to LAPAN satellite data acquisition, therefore a good performance is needed to get good data quality. One of the parameter to determine the performance of data reception is to know the G/T value (gain-to-noise temperature) of the receiving antenna. As a receiver, the noise in the antenna must be smaller than the gain value of the antenna. In this paper, the software is made to determine the G/T of a receiving antenna. This software is made so that the value of G/T can be known without making direct measurements and as a method of anticipation if the antenna component used for measurement is damaged. This software also saves the antenna power and the time needed to find out the value of G/T. In this study also performed a comparison of the G/T value in clear sky, cloudy and, rainy environmental conditions to determine the value of G/T in each condition. Then, a comparison is made between the G/T value of the software results with direct measurement. G/T values have a difference of 0.25 - 0.37 dB/K from measurements under normal conditions.
