Depointing influence of antenna on the link budget at the reception

摘要

In this article, we will carry out the calculation for the power budget for a connection between a station of reception and a geostationary satellite, while stressing a phenomenon which influences the power budget which is the "phenomenon of antenna depointing" and that for both segments: ground and space. The application enables us to consider the losses caused by this phenomenon on the power budget and its impact on our connection while passing by the two cases: depointing of the antenna on the ground, and the depointing of the antenna on board. Finally, we will try to draw up a comparative study to see which of the two antennas can be most affected.
