Tropospheric effects on satellite-earth links
Abstract
In ionospheric research, satellite-earth links are used to study the structure of the ionosphere. However, effects caused by the troposphere have been recorded on these links, along with the effects due to the ionosphere. In the present study, the effects caused by the troposphere in VHF and UHF satellite-earth links are analyzed. It is shown that very long periodic fadings (5 to 30 min) observed at 130 MHz and 400 MHz transmissions of stationary satellites are caused by cold fronts, ground inversions, and elevated inversion. These tropospheric structures also influence wave attenuation at frequencies greater than UHF.
