Boeing’s family of advanced beyond line-of-sight terminals (FAB-T) system has successfully demonstrated its end-to-end communication capability with the advanced extremely high frequency (AEHF) satellite during the first on-orbit testing at Boeing’s Systems Integration Lab in Huntington Beach, US.

During the testing, conducted since late last year up to February 2012, a Block 8 FAB-T enabled the AEHF SV-1 satellite to complete both extended-data-rate (XDR) and low-data-rate (LDR) communications.

The LDR and XDR data was then exchanged with the single channel anti-jam man portable and secure mobile anti-jam reliable tactical terminal used by the US Army and US Navy’s multiband terminal and follow on terminal and the Air Force minuteman minimum essential emergency communications network programme upgrade terminal.

Boeing vice president and FAB-T programme manager, Paul Geery, said the critical tests proved the integrity of FAB-T system, marking a step forward in delivery to the US Air Force.

"We have conducted additional successful high-speed data tests as we work to complete the remaining software integration and prepare for functional qualification tests," said Geery.

"Boeing is working to provide the Air Force with a fully capable, affordable system that supports the existing Milstar satellite constellation, its ground and airborne command-and-control terminals, and the new AEHF satellite constellation."

FAB-T successfully transferred and received data at 8mbps and also demonstrated terminal rekey and rekey requests through crosslink, and air force report-back capability during the AEHF Calibration Facility-Interim Command and Control terminal testing.

The system has displayed 24mbps receive capability, Navy report-back functionality and XDR Air Force report-back functionality by using satellite simulators, since the initial tests with the on-orbit AEHF satellite.

The series of tests highlight the key interfaces and functionalities of FAB-T operations.

The FAB-T, upon entry into operational service, is expected to offer secure wideband satellite communications to USAF, to help support command and control systems of the US nuclear forces.
