Computer Programs for Plotting Spot-Beam Coverages from an Earth-Synchronous Satellite and Earth-Station Antenna Elevation Angle Contours. Memorandum Number 72/4.
Stagl, Thomas W.; Singh, Jai P.
Computer programs prepared in connection with a project on Application of Communication Satellites to Educational Development (see EM 010 449) are described and listed in this memorandum. First, the data tape containing a digitized map of the world which was used for the programs is described. Then the first program, WORLDMAP, which plots the tape as a map with axes and grid lines, is discussed. MINMAP, the second program, which plots a specified part of the total map so that larger scale plots of a small area of interest can be obtained, is described next. A third program using the data tape, PERSPECT, intended to facilitate determination of the area coverage by satellite-borne shaped beam antennas, is covered, and finally, a modified antenna coverage program to be used to plot the footprints produced by the two off-axis S-band feeds on Applications Technology Satellite-F is described.
