MILSATCOM Architecture

Abstract

The Military Satellite Communications Systems Office (MSO) of the Defense Communications Agency has recently prepared an architectural framework for the evolution of military satellite communications systems through the end of this century. The realization of the goals of the architecture should provide significantly enhanced military utility to three functional classes of users. The strategic forces would be directed and managed through a two-way, highly survivable, jam-resistant Strategic Satellite System (SSS). The Tactical Satellite System (TACSATCOM II) offers a jam-resistant, low probability of detection, communications system for employment of ground mobile forces as well as tactical Naval and Air Forces. The future Defense Satellite Communications System (DSCS III U/IV) will provide the high data-rate users with increased jam resistance to perform their missions. These satellite systems will use higher frequency bands (EHF), on-board processing, and improved antenna techniques. To implement the EHF technology in a coherent fashion, the MSO has also prepared a Technology Development Program Plan which identifies and plans for the needed R&D efforts.
