Abstract: A satellite communication system, infrastructure, and method of providing same, involves inventorying certain types of pre-selected communication satellite payload modules and communication satellite bus modules based on analysis of anticipated communication satellite needs and providing each payload and bus module with a pre-configured standard interface coupling. When communication satellite parameters for a customer are received, a selection is made of one or more of the inventoried payload modules and also of the inventoried communication satellite bus module that is sized and configured to accommodate the selected payload module or modules. The selected payload module or modules are coupled to the selected bus module via the standard interface coupling, and the selected bus module is, in turn, coupled to a launch vehicle.
