Satellite Link Budget
Satellite Link Budget Q.1) An earth station antenna has a diameter of 30m has an overall efficiency of 68% and is used to receive a signal at 4150MHz. At this frequency system noise temperature is 79K when antenna points at the satellite at the elevation angle of 28 0 . What is earth station G/T under these conditions? If heavy rain causes the sky temperature to increase so that the system noise temperature rises to 88K, what is the new G/T value? Q.2) Define following terms i) Kepler’s First Law ii) Kepler’s Second Law iii) Geostationary Earth Orbit iv) Polar Orbit v) Low Earth Orbit Q...
