To demonstrate a dynamic hardware-in-the-loop testing concept for development of the EKV interceptor, GDC manufactured, tested and delivered to BOEING North American Space Division, a full three degree-of-freedom air bearing test bed, consisting of a cold gas attitude control system, a GDC flight computer, an AMRAAM Inertial Measurement Unit (IMU), a CCD camera, and a GDC custom telemetry link. As part of this effort GDC developed custom target centroiding software, which was integrated with GDC's standard flight control software. The project required an intensive effort by GDC personnel resulting in the delivery of the working system within eight weeks from receipt of contract. |
