GBS operates as a one-way broadcast capability supporting timely delivery of video products, unclassified & classified data for mission support and theater info transfer.
Beginning in 1998, GBS broadcasts via communication payloads on two UFO Ka-Band augmented satellites and all WGS satellites (Ka- and X-Band). Initial Operational Capability (IOC) for GBS Phase 2 Block II was declared in October 2008. The GBS Satellite Broadcast Manager (SBM) architecture transitioned to Defense Information Systems Agency’s (DISA) Defense Enterprise Computing Centers (DECC) in 2014 via two sites, Oklahoma City, OK and Mechanicsburg, PA. GBS provides service to 1000+ GBS receive suites deployed world-wide at Army, Marine, Navy, Air Force ground sites, shipboard and subsurface platforms and at NORTHCOM-sponsored homeland defense organizations worldwide.
In November 2016 four new GBS receive Suites (Figure 2) were operationally accepted by AFSPC. The four new Receive Suite Versions include: Transportable - designed for ground efforts in CCMD’s AORs; Suitcase – for ease of deployment in all environments; Rucksack – AFSOC man-pack support; and Shipboard – deployed on ships and submarines.
GBS operates as a one-way, wideband transmission service capable of supporting timely delivery of classified and unclassified data and video products for mission support and theater information transfer. GBS leverages commercial satellite broadcast technology to deliver large imagery and data files that would overload typical tactical network capacity. GBS disseminates Internet Protocol (IP)-based real-time video and large data files over-the-air (up to 45 Mbps) to garrisoned and deployed combat forces using net-centric prioritized delivery based on unit mission reception priority profiles. It is the primary method used to disseminate Full Motion Video (FMV) from Unmanned Aircraft Systems (UAS), such as the Predator and Reaper, to tactically deployed warfighters. GBS is a critical piece of the DoD's Intelligence, Surveillance, and Reconnaissance (ISR) architecture. GBS operates using SBM sites, Primary and Theater Injection Points (PIP/TIP), DoD Teleport Gateways, military and commercial satellites and Transportable Ground Receive Suites (TGRS). The SBM is the primary broadcast content site through which information products are transmitted once to the satellite via PIPs and Teleport Gateways and received by multiple simultaneous receivers saving valuable bandwidth. Through use of the TIP, GBS is capable of injecting information directly from within a theater of operations under the Theater Commander's control.
Initial Operational Capability (IOC) for GBS Phase 2 Block II was declared in October 2008. In early FY14, GBS transitioned the current SBM's to a Defense Enterprise Computing Center (DECC) hosted capability with data available via DoD Teleports and across the Global Information Grid (GIG). As of December 2016, GBS is transitioning from DVB-S1 to DVB-S2. The transition will be accomplished by April 2017.
Primary Function: High-capacity product dissemination (Imagery, UAS full-motion video, large data files) for mission-essential situational awareness
Primary Contractor: Broadcast: (DECC) Lockheed Martin and (legacy) Raytheon; Receive Suites Raytheon, General Dynamics and Windmill International; legacy sustainment/O&M Raytheon
Payload: Transponded Ka/Ku-band and transponded, cross-banded-X and Ka-band communications suites; UHF, WGS, GBS
Satellite Antennas: Fixed receive antenna for primary uplinks, steerable receive antenna for theater uplinks
Capability: Typically, 180 Mb/s per WGS satellite based on current allocation of 4 transponders per satellite for GBS content
