Sat Trans Theory/Lab

An overview of the basic concepts and techniques used in satellite communications is introduced. The three major segments of a satellite system, the space segment, the earth segment and the link between these segments, are described. A short introduction to satellite launching, followed by a discussion of the methods of determining antenna look angles. The antenna gain and beam-width equations are examined, with emphasis on the parabolic antenna. Uplink and downlink budgets are examined. Carrier-to-noise ratio, bit energy to-noise density ratio and gain to-noise temperature ratio are studied. Frequency modulation and multiphase modulation methods are investigated. The laboratory uses several software simulation tools to analyze the different segments of the satellite communication networks. The link budget analysis, launching phase analysis and others are performed to improve understanding of the theoretical concepts. Dish antenna, transmitter/ receiver, waveguides and spectrum analyzer are utilized to enhance experiments.
