Satellite communication networks can be an integral part of the newly emerging national and global information infrastructures (NII and GII). Satellite communication offers a number of advantages over traditional terrestrial point-to-point networks. Satellite networks can cover wide geographic areas and can interconnect remote terrestrial networks ("islands")...
