Global Broadcast Service (GBS)Volume VI – Model Contract – Attachment 31 <strong>SRD</strong> OVERVIEW1.1 ScopeThis document is the Global Broadcast Service (GBS) System Requirements Document (<strong>SRD</strong>). It providesguidance for the GBS Phase II System functional and performance requirements for the "Defense EnterpriseComputing Center (DECC) Architecture" to be implemented in 2008 and beyond. It will be used to establish acontractual baseline requirements document. Each requirement has been identified with a unique number that willbe used to track the requirement through the GBS Program lifecycle. As the GBS program transitions operationsfrom the IP Enhanced Architecture (EA) at the NCTAMS (located at Wahiawa, Hawaii and Norfolk, Virginia) tothe DECC there will be two relevant program <strong>SRD</strong>s, the IP EA <strong>SRD</strong> version 2.1, dated March 2005 and thisdocument for the DECC Architecture.1.2 PDM IV BackgroundOn 13 December 2006, the Deputy Secretary of Defense England approved Program Decision Memorandum(PDM) IV. This document directed the <strong>Air</strong> <strong>Force</strong> to:1) Transfer the Satellite Broadcast Manager (SBM) functions to DECC with new hardware and softwarearchitecture by FY 2010;2) Implement system transmission security (TRANSEC) via the Joint IP Modem (JIPM);3) Provide operations, maintenance, and sustainment for the GBS program throughout the life of GBS.This <strong>SRD</strong> addresses items (1) SBM transition to the DECC, (2) JIPM implementation, and Maintenance, andSustainment of the system from item (3). Operations of the DECC system will be addressed in an update of theCONOPS.1.3 CONOPS BackgroundA new version of the GBS CONOPS for the IP EA system was approved on 21 June 2007, which will supersedesthe 24 January 1996 CONOPS. The CONOPS will be updated again to reflect the DECC Architecture andoperations.1.4 System OverviewJoint tactical operations require high speed, high volume multimedia communications and information flow fordeploying, deployed and garrisoned forces. The GBS system employs emerging technologies that allow thewarfighter to satisfy these information requirements in the conduct of modern warfare. An extension of the GlobalInformation Grid (GIG), GBS provides worldwide, space based, IP over DVB-S/S2, broadcast of high speed, onewaytransmission of video, imagery and other information to support forces in garrison, in transit and in theater.GBS provides relief to overburdened communications systems already in place and provides information topreviously unsupportable users. The GBS must be accessible to end users and must therefore employ readilyavailable commercial technologies, which are inexpensive and easily integrated into existing systems andprocesses, yet not so unwieldy as to be unusable by smaller and more mobile units. To this end, GBS usesbroadcast payloads on a variety of Government owned and operated geosynchronous satellites, augmented byleased commercial satellite services, and a system of fixed and transportable injection terminals interconnectedvia high-bandwidth terrestrial communications links.The GBS system consists of three physical segments: Broadcast, Space, and Receive. The associated systemarchitecture is shown in Figure 1.30 March 2009 • Contract Number: FA8726-09-C-0006Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this proposalVolume VI-5.0-106
