Boeing completes testing of beyond line-of-sight terminals for AEHF, Milstar

Boeing has completed the successful testing of the software qualifications and systems integration for the Air Force's Family of Advanced Beyond Line-of-Sight Terminal (FAB-T) program, the company said Jan. 29.

The mission of the FAB-T program is to furnish protected wideband satellite communications among ground and airborne terminals for the command and control of U.S. nuclear forces.

The company's team also has demonstrated FAB-T's integration with the Advanced Extremely High Frequency and Milstar mission control subsystem, which commands both satellite constellations, the company said. The test validated FAB-T's ability to control strategic satellite communications payloads on orbit. The tests were completed in the company's facilities.

The AEHF and Milstar satellite constellations will relay FAB-T communications once FAB-T is operational, the company said.

During testing, FAB-T also transmitted data using both low-data-rate and extended-data-rate communications protocols. The system's advanced XDR capability offers Internet-like functionality and improved speed compared with earlier systems and software.

Boeing and the Air Force agreed on a set of additional FAB-T capabilities in April 2012, including Presidential and National Voice Conferencing, to be developed under the company's contract. The Boeing team has implemented those capabilities and expects to enter functional qualification testing early this year.
