COTS Terminal Transfer Secure Video, Voice and Data Over Military WGS Satcom


A recent technology demonstration conducted by the U.S. Air Force and Defense Information Systems Agency (DISA) validated the use of commercial off the shelf (COTS) aero-mobile low-profile Ka-band terminal over DOD Wideband Global Satcom (WGS) system. Test criteria included an airborne bi-directional video teleconferencing session while simultaneously running IP file transfer applications.

The system being demonstrated employed the Advanced Multiband Communications Antenna System (AMACS) terminal provided by iDirect Government Technologies (iGT). The test demonstrated the system’s capability to transmit and receive high-speed information, employing the iGT’s Evolution platform, which uses a Current-Force-Modem on multiple satellite bands, and the AMCAS low-profile antenna.

“This demonstration of the Aero- Mobility features over WGS using Commercial-Off-The-Shelf (COTS) Technology is an extremely important step towards providing viable aero-mobile communications by using a mixture of the readily available commercial solutions and DoD assets” Shaum Mittal, Chief Engineer, PEO-COMMS, DISA, explained.

iGT demonstrated its next-generation transmission standard (DVB-S2) with Adaptive Coding and Modulation outbound technology with a Multi-Frequency Time Division Multiple Access inbound IP-based platform. The demonstration also included successful evaluations of iGT’s latest AES-256 based Transmission Security software. “With proven on-the-move satcom systems, airborne capabilities can be used on both manned and unmanned airborne military platforms including intelligence, surveillance and reconnaissance missions and to boost emergency disaster response,” said John Ratigan, President of iGT.
