(U) Global Broadcast Service (GBS) Phase II

(The effects of any budget/program decisions made since the information was collected during 1997-98 are NOT reflected in the National Security Space Road Map (NSSRM).)

Overview: (U)
(U) The Global Broadcast Service (GBS) addresses long term DoD needs in information transmission, reception, and handling.  GBS Phase II will utilize modified Navy UHF Follow-On (UFO) satellites with military band (Ka) transponders.  This phase shifts from using commercial satellites (Phase I) equipped with Ku band transponders.  It will be followed by Phase III a worldwide fully capable GBS system will be hosted on the Advanced Wideband Satellites.

Description: (U)
(U) Phase II of the GBS program provides for an interim GBS capability by modifying Navy UHF Follow-On (UFO) satellites with military band (Ka) transponders.  GBS transponders provide the UFO satellites with three broadcast beams which provide 24 Mbps channel capabilities.  With the success of Phase I of the GBS program, a technology demonstration program which uses leased commercial Ku-band satellites, GBS Phase II shifts to utilizing the military UFO satellites.  

(U) The GBS program also develops a Broadcast Management capability and procures receive elements as part of the program.  Key efforts involved in the development of ground infrastructure include adaptation of receive terminals for quantity procurement, purchase of satellite uplink systems, development and purchase of broadcast manager capabilities, and development of high-bandwidth cryptographic techniques.

(U) The GBS Joint Program Office will fund the procurement of FY97 Primary Injection Points (PIPs) and a basic quantity of 50 Ground Receive Terminals (GRTs) for each Service (Total 150).  The Army will procure an additional 42 GRTs and Broadcast Management (BM) suites.  The Navy will procure a total of 318 ship and 74 submarine terminals, 70 fixed site terminals, and 74 portable shore terminals.

User Impact: (U)
(U) The Global Broadcast Service (GBS) addresses long term DoD needs in information transmission, reception, and handling by developing a wideband, high capacity communications system and the required fixed and deployable terminals.
