Satellite Transmission Toggle navigation

The basic concepts and techniques used in satellite communications are introduced.
The three major segments of a satellite system: the space segment, the earth
segment and the link between these segments are explained in details. An introduction
to satellite launching is followed by a detailed discussion of different orbits and methods of
allocating geostationary orbit to communication satellites are addressed. Three main frequency
bands allocated to communication satellites are discussed in details. The atmospheric and free
space loss, the effects of rain attenuation, elevation angle, antenna’s figure of merit and other
factors affecting signal propagation are explained. Uplink and downlink transmissions and the
link budgets are examined and the carrier to noise ratio, bit energy to noise density ratio and gain
to noise temperature ratio are explained. Different modulation and multiple access methods are
covered. The laboratory part of this course utilizes several software simulation tools to analyze
the different segments of a satellite communication network. The link budget analysis,
launching phase maneuvers and impacts of different parameters affecting signal transmission and
reception are performed to improve understanding of the theoretical concepts learned in the
lecture part of the course. The impacts of other Earth and Atmospheric parameters such as sand
storm, rain attenuation, Van Allen Belts and Tropospheric Scintillation on signal propagation are
examined to enhance learning.
