a. Overall Mission Area. Joint operations require high-speed, multimedia communications and information flow for deployed, on the move (in-transit), or garrisoned forces. Current and future joint operations require taking advantage of new technology and information transfer systems to support modern warfare. The Global Broadcast Service (GBS) will augment and interface with other communications systems and provide a continuous, high-speed, one-way flow of high volume information to deployed, on the move, or garrisoned forces. GBS will support routine operations, training and military exercises, special activities, crisis, situational awareness, weapons targeting, intelligence, and the transition to and conduct of opposed operations short of nuclear war. GBS will provide the capability to quickly disseminate large information products to various joint and small user platforms. Coverage will be worldwide.
b. Type of System Proposed. The Global Broadcast Service (GBS) system is proposed as a satellite-based broadcast capability.
The broadcast signals would be transmitted to a large inventory of user receive units within the CINCs' AOR. The basic capability, previously unavailable, would provide a high data rate bit stream of video, data, imagery, and other information from high powered broadcast satellites to a large section of the force structure and numerous warfighting platforms. The satellites will eventually be required to provide continuous and simultaneous coverage to broad regions of the earth's surface in support of widely dispersed forces. The high data rate bit stream would be transmitted from a limited number of fixed and deployable injection terminals and controlled by the CINCs, and managed by the broadcast management segment in each satellite field of view. The information being transmitted is envisioned to have been received from a myriad of sources and packaged for the high data rate bit stream by the Satellite Broadcast Manager (SBM) at the direction of the CINCs.
The CINCs theater information manager is concerned with establishing CINC priorities, authorizing user access, coordinating broadcast schedules, and allocating resources. The system will take maximum advantage of commercial products, technologies, and non-developmental items. Decisions previously made: The Global Broadcast Service was designated as a joint program on 27 March 1996, by direction of the Under Secretary of Defense for Acquisition and Technology (USD(A&T)). A number of decisions were embedded in the formal program designation and have also been approved by the Congress.
These include the current phased approach for providing satellite broadcast payload assets over time. A major decision was made to place a limited capability GBS payload onboard the last three UHF Follow-On (UFO) spacecraft (UFO 8, 9, and 10). The major performance features of the UFO GBS payload were briefed to and endorsed by the Joint Requirements Oversight Council (JROC) and the Expanded Defense Resources Board (EDRB). Due to the decision regarding the UHF Follow-On spacecraft GBS capability, the space segment assets will have at least three distinct phases of fielded capability. The three phases are described below:Phase 1 (FY96 - FY98): Limited leased commercial satellite services operating at Ku-band for concept of operations development, demonstrations, and limited operational support.Phase 2 (FY98 - FY06+): Payload packages hosted on UHF Follow-On satellites 8, 9, and 10 with the downlink broadcast operating at 20.2-21.2 GHz (Ka-band). As only three UHF Follow-On satellites will be equipped with the GBS Ka-band payloads, the continued lease of commercial satellite services at Ku-band will be required to augment UFO GBS where coverage gaps exist and may be required to complement the UFO GBS limited number and size of downlink beams.Phase 3 (FY06+):
The objective GBS on-orbit capability will provide increased capacity, worldwide coverage, and the capability to broadcast near continuous or time critical information to broadly dispersed users. The specific solution for the GBS long-term capability will be developed in accordance with the DOD MILSATCOM Architecture as maintained by the DOD Space Architect.This GBS ORD accommodates the decisions that have been made regarding the phased approach for providing GBS on-orbit satellite payload capabilities, the requirements for the fixed and transportable injection terminals along with their associated broadcast management functions that will support the use of the UHF Follow-On GBS payloads, and those that will support the use of the Phase 3 space segment assets.
This ORD also describes the requirements of the user receive units that will receive information from the UHF Follow-On satellite GBS payloads and that will receive information from the Phase 3 space segment assets. Additionally, this ORD describes the requirements for the Phase 3 GBS space segment capability, as known today.
(1) Space Segment. The GBS space segment will be implemented in three phases. Ground based Telemetry, Tracking and Control (TT&C) resources will be required to manage the space segment to ensure payload objectives are achieved. The TT&C resources will be responsible for the space segment's "health" and will resolve any space segment anomalies.
(2) Broadcast Management Segment (BMS). The broadcast management segment will accept, coordinate, and package (if required), information (general broadcast products, smart push products, user pull products) from national and theater sources to be broadcast based on the direction and priorities of the supported CINCs, commanders, and their functional users. The BMS will also include the functions necessary to support the efficient use of GBS. These functions include, but are not limited to, providing interface protocols and standards to allow information producers to submit information in a form acceptable by the GBS broadcast, coordinate with Theater Information Managers (TIMs) to apply CINC dissemination priorities to information destined for broadcast in their respective AOR, coordinate with TIMs and information producers to attempt to satisfy users requests forwarded by the TIM and unable to be satisfied by other means. The broadcast management segment will include both transmit management and receive management functions. The transmit function will manage the information flow to the appropriate injection point for transmission to the satellite. The receive function will support the filtering of user determined relevant information from the broadcast streams and the dissemination of the receiver information from receive suites to end users' servers or application. The broadcast management segment will maximize on-orbit capabilities to include uplink and downlink beam steerage and transponder configurations. The broadcast management segment will require manning to meet operational requirements.
(3) Primary Injection Point (PIP): The PIP will uplink information received from the broadcast management segment to the space segment. The PIPs will be fixed facilities. For Phase 2 there will be a PIP located within the footprint of each GBS equipped UFO satellite.
(4) Theater Injection Points (TIP): The TIP includes transmit broadcast management and transmit uplink capabilities necessary to accept, coordinate, package, and to transmit vital CINC/CJTF/component directed in-theater information to the space segment. The TIP will be a transportable system located ashore or afloat. Afloat operations will require modifications to the TIP.
(5) Receive Suites: The receive suite includes the receive terminal, cryptographic equipment, (when required) and the receive broadcast management equipment. The receive terminal will consist of a small satellite antenna and receiver equipment that will receive and convert downlink GBS radio frequency (RF) signal into a bit stream. The receive broadcast management equipment will provide the functions necessary to convert the broadcast into a video and DII and COE compatible format. The receive suite will be owned, operated, and fielded to lower echelons. The user is responsible for all peripheral devices (i.e., TV, computer hardware, monitor, special encryption devices, etc.) needed to make information useable.
This architecture will compensate for differences in security (classification) levels and classes of users, and the ways in which users receive information products. It is the user's responsibility to process user addressed information in the manner that best suits their needs. Depending on the user's needs, receive suite equipment will support a variety of configurations, from stand alone to networks
Many products today require transmission of imagery and data files with sizes in the megabyte range that require excessive time to transmit via existing low data rate channels. Additionally, many of these products require the use of multiple low speed channels to transmit to multiple users. The implementation of GBS will provide a worldwide, high capacity, one-way transmission means for a variety of data, imagery, and other information required to support joint forces.
a. Threat to be Countered. In a strategic environment threats are diverse and multi-national.
Threats include regional instability caused by ethnic, religious, historical, and economic disputes; proliferation of weapons of mass destruction; and trans-national dangers such as global terrorist groups and drug traffickers. From a tactical perspective, theater commanders are challenged by regional factions seeking to expand their influence by coercion or force. These potential opponents range from nations with modern conventional military forces, organized terrorists and insurgent organizations to small bands of individuals armed with any weapon available. b. Projected Threat Environment.
The threats to GBS include warfare directed against the GBS broadcast and GBS information systems, electronic warfare directed against the satellite links, and physical destruction of the GBS segments.
The general threat environment for all information systems is described in the Defense Intelligence Agency (DIA) publication DST-2660F-210-94, Command, Control, Communications, Computers, and Intelligence Systems and Networks; Telecommunications Networks; and Automated Information Systems Threat Environment Description (TED), dated 15 January 1994. The general threats to GBS satellite links are described in the DIA publication DST-26110S-111-94, Electronic Warfare Threat to Satellite Communication Links - Foreign, dated 31 March 1994. The general threat environment for the GBS space segment is described in the National Air Intelligence Center (NAIC) publication NAIC-1571-727-95, Space Systems TED, dated 11 September 1995. A MILSATCOM System Threat Assessment Report (STAR), to include threats to the GBS, is being developed by the 497th Intelligence Group and National Air Intelligence Center.
