Global Broadcast Service (GBS): The GBS Program is a United States Air Force initiative managed by the GBS Military Satellite Communications (SATCOM) Logistics with Headquarters Air Force Space Command oversight. The mission of the GBS system is to provide worldwide continuous, one-way, high-speed information flow over military and commercial satellites to quickly disseminate information products to deployed and in-garrison forces. GBS delivers the following products to deployed, at the halt, and garrisoned users: imagery, intelligence, training, 24-hour commercial news, tactical Full Motion Video (FMV), weather services, and other large volume, rapid delivery content as necessary. GBS is capable of broadcasting over Ka, Ku, and X-bands utilizing both Department of Defense military (e.g. Ultra-High Frequency Follow-On and Wideband Global SATCOM) and commercial satellites (e.g. Horizons-1). GBS is comprised of three segments: terminal segment, broadcast management segment, and space segment. The Marine Corps is retrofitting the Legacy AN/ TSR-9 Transportable Ground Receive Suite and adding the Suitcase Portable Receive Suite system to become the AN/TSR-11 and AN/PRS-11 systems respectively. The AN/TSR-11 is a ground station that receives Ku-band and Ka-band satellite broadcasted products from both military and leased satellites. The AN/TSR-11 will have the same footprint as the existing AN/TSR-9 configuration. It can operate both classified and unclassified enclaves, simultaneously allowing both types of data to be received, processed, and viewed, in accordance with cybersecurity requirements, using the included equipment. The AN/PRS-11 has a significantly smaller footprint than the AN/TSR-11 and is intended to support the Special Operations Forces with a basic GBS capability (single enclave, classified or unclassified, Ka band only) in austere and remote locations.

Operational Impact

The goal of GBS is to provide the warfighter with information that allows him to act inside the decision cycle-time of his adversaries. The Defense Information Systems Agency-Defense Enterprise Computing Centers architecture provides a centralized location for supporting worldwide, continuous operations, management, and control assets assigned to GBS. GBS primary functions are high capacity product dissemination (Imagery, Unmanned Aerial Vehicle FMV, large data files) for mission essential situational awareness. The essential functions of GBS include broadcast planning, broadcast management, content delivery, and content reception. The GBS architecture is a content priority based broadcast. This ensures the most critical information is delivered first. GBS supports training and military exercises, special activities, crisis operations, battlefield awareness, weapons targeting, and Intelligence, Surveillance, and Reconnaissance requirements.

Program Status

Post Milestone C. Current program office efforts include the fielding of AN/PRS-11 to Marine Special Operations Command units. The program office will begin procurement of the AN/TSR-11 in 4th Quarter Fiscal Year 2018, and begin fielding in 2nd Quarter Fiscal Year 2019.
