Measurements of ASTRA satellite signal parameters

In this work, after a basic theoretical background on the ASTRA satellite constellation and their satellite signal and channels, our model for measuring the satellite signal reception in our laboratory is presented. The satellite signal was received with a parabolic antenna, led over an LNB converter and satellite in-line amplifier to a digital satellite receiver and a television set. The strength of satellite receiver’s input signal was measured with a spectrum analyzer. The communication channel width was analyzed.
