Abstract :
This paper presents the measurement results of tropospheric scintillation at frequency Ku band with different locations and elevation angles. The number of occurrence time of satellite signal fluctuations from three sites are compared. The results show that there is a good correlation between the daily temperature and the scintillation occurrence time. The occurrence time of scintillation increases when the daily temperature increases. The maximum value is taken around 14:00 where the daily maximum temperature is occurred and the minimum value during nighttime to early morning where the daily temperature is low.
