Space Platform concepts

Abstract

Preliminary conceptual approaches for both low earth orbit and geostationary Space Platforms have been developed in response to user requirements. These requirements include payload needs for: operational autonomy, power, size, environmental control (including dynamic, electromagnetic, gaseous, and particulates), on-orbit accessibility, communication and pointing. The concepts developed include both multipurpose and discipline dedicated platforms. In this paper these concepts, their evolution, and their relationship to the needs of the user are presented and discussed.
