Global Broadcast Service (GBS).

摘要

The Global Broadcast Service (GBS) is an extension of the Global Information Grid that provides worldwide, high capacity, one-way transmission of video (especially from Unmanned Aerial Vehicles), imagery and geospatial intelligence products, and other high-bandwidth information supporting the nation's command centers and joint combat forces in garrison, in transit, and deployed within global combat zones. It employs readily available satellite-based commercial technologies that are relatively inexpensive and easily integrated into existing systems and processes, yet are not so unwieldy as to be unusable by smaller and more mobile units. To this end, GBS currently uses broadcast payloads on two Ultra-High Frequency Follow-On (UFO) satellites, leased commercial satellite transponders, and the Wideband Global SATCOM constellation. Theater Injection Point terminals provide a deployable Ka-band uplink capability that can operate directly from a Combatant Commander's (CCDR's) Area of Responsibility. Information sources deliver products for daily broadcast via Defense Enterprise Computing Centers (DECCs) operated by the Defense Information Systems Agency (DISA). Content is based on defined mission profiles approved by the CCDR's Theater Information Managers (TIMs). The GBS Operations Center provides broadcast planning and coordinates beam movement as well as 24/7/365 support to users worldwide.
