Abstract: To develop an improved new prediction model form measurement of tropospheric scintillations for Indian Climate of satellite ka band signals which is used in adaptive link control in the design of satellite communication system. Because in Indian climate will be tropical and changing seasonally. Due to small variations occurred in refractive index and rapid signal fluctuations occurred in the signal amplitude and angle of the signal in turbulent layer when the received signals passing through it, then .This is called scintillation. The scintillations more significant in ka band signals. Propagation experiment carried out at The SAC of ISRO on Ka-band over India. To this purpose, the GSAT-4 satellite will board two antennas at 30.5GHz and 20.2GHz in linear polarization.
Keywords: Refractive Index, Monthly Averaged Pressure, Monthly Averaged Temperature, Relative Humidity and Height, Ka band, Tropospheric Scintillations.
Scope of the Article: Regression and Prediction
