Smart Data Node in the Sky

Abstract

A document discusses the physical and engineering principles affecting the design of the Smart Data Node in the Sky (SDNITS) -- a proposed Earth-orbiting satellite for relaying scientific data from other Earth-orbiting satellites to one or more ground station(s). The document characterizes the problem of designing the telecommunication architecture of the SDNITS as consisting of two main parts: (1) finding the most advantageous orbit for the SDNITS to gather data from the scientific satellites and relay the data to the ground, taking account of such factors as visibility and range; and (2) choosing a telecommunication architecture appropriate for the intended relay function.
