Defense information system network satellite service

Abstract

Services and agencies continue to deploy IP SATCOM systems while awaiting migration to the joint IP modem (JIPM). As the JIPM nears production, challenges such as establishing responsibility for development of a common end user terminal, satellite and hub resource allocation and management, and long term sustainment for the end-to-end SATCOM infrastructure must be addressed. Currently, the DoD gateway hosts numerous IP SATCOM systems including Linkway, iDirect, and DVB-RCS. All of the SATCOM systems are responsible for providing defense information systems network (DISN) connectivity and services to the warfighter. The Defense Information Systems Agency (DISA) aims to establish commonality and interoperability among the current capabilities. To achieve this end state, DISA is evaluating the establishment of a DISN satellite service (DSS) provided as an extension of existing IP SATCOM systems, DISN transport, and RF services embedded at the DOD gateways. As part of the DISN satellite service, DISA is designing a ubiquitous IP SATCOM suite capable of providing DISN connectivity and access to all of the DISN services including VTC, VoIP, NIPR, and SIPR. This paper will further elaborate the proposed DSS end user terminal components and capabilities and the advantages it provides to the deployed warfighter.
