Introduction
A shift towards a new generation of advanced Command Post Terminals (CPT) is happening gradually on several frontiers. This new generation, known as the Family of Advanced Beyond-Line-of-Sight Terminals (FAB-T) is expanding upon existing foundations by adding new software and hardware. The Inertial Labs Antenna Reference Unit (ARU) is used on FAB-T and currently belongs to the Air Force Command Post Terminal (AFCPT) program. The upgrades are to enhance the performance of satellite control functions. The United States Air Force purchased the Inertial Labs AHRS for antenna modification kits, in order to keep the AFCPT systems at a state of Initial Operating Capability (IOC).
