摘要：The electromagnetic signal from the satellite while travelling down to the earth should pass through various layers of the atmosphere like troposphere, stratosphere, ionosphere etc. These layers won�t act as a transparent layer but instead they provide some obstacles in the path of the signal travel and changes the characteristics of the signal. With the advancements in technology the users are not at all compromising in using the applications like data applications, web applications, simultaneous audio video transfers, etc. which results in excess usage of the conventional frequency bands. So, the modern applications are likely to be designed at higher frequency spectrum i.e. Ku, Ka & V bands. The influence of the layers mainly depends upon the frequency of the signal. As we are dealing with the frequencies above 10 GHz the ionosphere acts as a transparent layer but the troposphere influence the signal characteristics. In this paper, we are going to analyze and compute the tropospheric impairments like attenuation due to rain and tropospheric scintillations for the geographical area of K L University, Vaddeswaram located at 16.44oE latitude and 80.62oN longitude.
