Abstract:The size of commercial GEO satellites has steadily grown as a result of the telecommunications market demanding more satellites with higher power and more transponders. Many analysts within the satellite manufacturing and launch industries see this trend continuing. In 1996, the Commercial Space Transportation Advisory Committee (COMSTAC) was split among two possible scenarios for the growth in satellite mass over the next decade: either satellite mass growth would plateau or it would continue to rise. By 1997, COMSTAC concluded that commercial GEO satellites would likely continue to grow in size and mass and that heavy commercial GEO satellites would comprise a larger proportion of the market than had initially been predicted. Satellites heavier than 9,000 pounds to GTO are expected to increase from about 10 percent of the market today to approximately 50 percent by 2010. This trend, according to COMSTAC, will result in a corresponding
percentage reduction in the intermediate market segment (satellites weighing 4,000 to 9,000 pounds).
