The rain attenuation in Ku-band satellite signal at Bangkok

Abstract

This paper presents the experiment and result of rain attenuation of satellite signal on Ku-band, downlink of Thaicom 3 at King Mongkut's Institute of Technology Ladkrabang (KMITL) in Bangkok (Longitude: 100.7 °E, Latitude: 13.7 °N). The relation of rainfall and the rain attenuation on ground station are presented. Correlation between 1-second, 1-minute and 30-minute integration time of the rainfall rate is also presented. We compare the data recorded at Bangkok with ITU-R model. This experiment has been held for 1 year from June 2004 to May 2005. © 2005 IEEE.
