The Aerial Wetted Path of Geostationary Transmission

The aerial effective wetted path of geostationary satellite transmission focused to the Earth´s surface was both defined taking into account the warm sector of rainy cloud and estimated as a function of signal strength. A standard path of 4.88 km was obtained for Caracas with a 60 cm dish parabolic receptor pointing with a 55° elevation angle to an associated direct TV satellite in Ku band. Such function helps to estimate rainfall intensity with ±3 mm/h bulk error for stormy weather. Myriad of users of direct TV and other satellite applications with theirs receptors providing signal strength may apply the present issue to estimate paths and rain rates but doing verifications and adjusts by new coordinates and new dish sizes.
