Computer-Aided Communication Satellite System Analysis and Optimization.
Stagl, Thomas W.; And Others
Various published computer programs for fixed/broadcast communication satellite system synthesis and optimization are discussed. The rationale for selecting General Dynamics/Convair's Satellite Telecommunication Analysis and Modeling Program (STAMP) in modified form to aid in the system costing and sensitivity analysis work in the Program on Application of Communication Satellites to Educational Development is given. Modifications of STAMP implemented on Washington University's IBM 360/65 computer include: 1) extension of the six beam capability to eight; 2) an option for generation of multiple beams from a single reflector system with an array of feeds; 3) improved system costing to reflect the time-value of money, growth in earth-terminal population with time, and to account for measures of system reliability; 4) inclusion of model for scintillation at microwave frequencies in the communication link loss model; and 5) an updated technological environment. Results of a sensitivity analysis of the modified STAMP are discussed to indicate the program's capabilities. Also described are computer programs for plotting footprints of narrowbeam antennae onboard on earth-synchronous satellite, full field of view for a prescribed subsatellite point, and contours of earth station antennae elevation angles.
