Abstract
DSN earth stations typically transmit more power than that required to meet minimum specifications for uplink performance. This article presents the results of a study of energy and cost savings that could result from matching the uplink power to the amount required for specified performance. The Galileo mission was selected as a case study. Although substantial reduction in transmitted energy is possible, potential savings in source energy (oil or electricity) savings are much less. This is because of the rising inefficiency in power conversion and radio frequency power generation that accompanies reduced power output. The work described in this report is part of a continuing study intended to guide future development and management of the DSN in the changing environment of space exploration.
