1. 1. Satellite signal attenuation due to atmospheric influences in northern Sweden

   University essay from Umeå universitet/Institutionen för fysik

   Author : Adrian Stigsson; [2024]
   Keywords : ;

   Abstract : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. READ MORE

3. 2. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Akila Wajirakumara; [2021]
   Keywords : ;

   Abstract : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.
