CODE FIEC03194 NUMBER OF CREDITS : 4 Theoretical: 4 1 Practical: O

2. COURSE DESCRIPTION

The course provides the mathematical elements that describe the geographic and geometric aspects of space and their orbits, supported by Kepler's laws. From previous knowledge of signal propagaban, qualitatively and quantitatively analyzes the effects of the space environment and atmospheric about the electromagnetic signal. Details the items and blocks that make up the space segment and the ground segment. It analyzes the digital signal processing and sets the parameters of spectral efficiency. We review the forms of access to satellite signals, and finally, we discuss applications for telephony, data and television services, provided by different satellite service companies. The course is an application of the body of knowledge that the student has acquired, to structure a telecommunications system.
