The GBS Secure Media Router

AERONIX GBS PRODUCT OVERVIEW

Aeronix has developed a Global Broadcast Service (GBS) satellite receiver which receives conditional access transmissions from source locations in US. The product receives, descrambles, and provides the data as IP.

The Irdeto Conditional Access (CA) descrambler runs on the device, supporting stream definitions entitled on the Smartcard. The MPEG data stream is then converted into IP packets which are exported onto a network to authorized clients. Ground-based (vehicle) operation is currently supported, and miniaturization to a half-size man-portable version is viable using a PCMCIA Type III form factor already developed and demonstrated as a prototype.

GBS SYSTEM BACKGROUND
The GBS system is a space to ground, high-data-rate communications link. It provides a worldwide high data rate broadcast capability that "pushes" a high volume of information to widely-dispersed, low-cost receive terminals. GBS provides efficient high-data-rate connectivity
to many distributed information sinks and users who receive the broadcast directly on small, inexpensive user terminals. Examples of data to be distributed include digitized imagery, logistics data, weather data, maps, operational orders (Air Tasking Orders, for example), and video.

GBS is an extension of the Defense Information Systems Network (DISN) and a part of the overall DoD MILSATCOM Architecture. As such, it employs an open architecture which can accept a variety of input formats. It exploits commercial off-the-shelf (COTS) technology. It interfaces with, and augments other major DoD information systems, such as the Global Command and Control System (GCCS), as well as other theater information management systems.
