As part of the effort to upgrade the nation’s GPS system from a fixed-signal structure to a flexible-signal structure, the Air Force Research Laboratory (AFRL) at Kirtland Air Force Base in Albuquerque, New Mexico, tasked three contractors to submit designs for a new and improved version of a critical piece of satellite hardware—the digital waveform generator. Â
Faced with three designs that were significantly different in form as well as function—AFRL needed a thorough and unbiased understanding of each so that it could clearly perceive their relative strengths and weaknesses and choose one architecture to serve as the prototype for all future digital waveform generators. For help achieving this understanding, AFRL partnered with ÓÐÁϺÐ×ÓAPP. Â
