GBS next generation architecture

Abstract

The global broadcast service (GBS) provides a worldwide, high-capacity, one-way transmission of classified and unclassified video, imagery, and other information as required to support joint military forces in garrison, in transit, and in theater. GBS enables real-time information product delivery to the warfighter by providing satellite resources that are shared based on CINC/JTF commanders' priorities, operational locations, and the platform capabilities of the deployed users. The rapid technological evolution of the commercial satellite Internet service provider (ISP) market over the past decade has enabled the GBS JPO and the Defense Information Systems Agency (DISA) to re-evaluate the suitability of commercial technology and equipment for an enhanced GBS architecture. Led by the GBS JPO systems engineering team, the DoD is subsequently planning to perform a technology refresh of the GBS architecture, focusing on DVB open standards, IP data transport, and commercial communications technology. This technical re-design of the GBS architecture will significantly enhance the capabilities and real-time services that GBS provides to the deployed warfighter. This paper explores the design principles, engineering strategies, and key technologies that will enable the transition of GBS to a next generation military SATCOM system.
