In this lecture, I'll cover some satellite communication basics like pros and cons of different orbits, the characteristics of a satellite communications link and the difficulties regarding noise and attenuation when handling high frequency satellite communication systems. After a brief introduction to the history and development of satellites in general, we'll talk about different orbits and their characteristics regarding space conditions. After that, we'll have a look at a typical satellite communications link including channel characteristics, communications equipment and frequency considerations, before moving on to access techniques. If there's still time, there might be a short part about satellite navigation, too. And yes, to meet our need for pretty pictures, thematically related postage stamps (partly from a private collection) will be used to illustrate the topic.
