Implications of power flux density constraints of satellite systems
Abstract
A set of interrelated technical constraints that have been suggested as a possible means of promoting efficient orbit utilization is discussed. An initial analysis of this proposal is provided and its implications on system design and orbit utilization are discussed. It is noted that values of ABCD that may be considered orbit efficient could preclude the implementation of small earth-station networks. The basic difficulty is seen in the spot beam satellite antennas which are more sensitive to up-path interference and yet permit the use of small earth antennas by delivering high EIRP. It is not implied that small earth station antennas coupled with narrow-beam satellite antennas are necessarily orbit and spectrum inefficient, since the latter tend to permit greater frequency re-use. It is noted, however, that this dimension of the problem is not truly reflected in the ABCD approach.
