14:00 - 18:30,
The lecture concentrates on communication aspects of modern satellite communications systems which play an important role in today's world of wireless communi-cations. A profound understanding of modulation and multiple access techniques and channel models is required.
The lecture starts with a brief sketch of the advent of satellite communications. Then, a detailed treatment of the various satellite orbits and orbit geometries is given followed by the description how to position a satellite in orbit and how to communicate during this procedure (TT&C).
Furthermore, satellite and earth station structures, the suitability of various modulation and multiple access schemes for satellite communication and the satellite channel are described. All relevant parameters affecting the communication link are summarized in a link budget which enables proper design of a satellite communications system.
Finally, as one of the main topics of the lecture, examples of today's operating and of future satellite communications systems are presented. GEO systems as well as the recently introduced LEO mobile satellite systems are described (Iridium, Globalstar and Teledesic). Moreover, satellite navigation systems (GPS) are treated.
