Navigation Technology Satellite - 3: A Vanguard for Space-based Position, Navigation, and Timing

摘要

Navigation Technology Satellite - 3 (NTS-3) is an advanced satellite navigation flight experiment of the Air Force Research Laboratory that will mature next generation technologies across space, ground control, and user equipment segments. In August 2019, NTS-3 was designated an U.S. Air Force Vanguard program highlighting the importance of rapid advancement of space-based Position, Navigation, and Timing (PNT) and transition to the U.S. Air Force. As a unique testbed in geosynchronous orbit, NTS-3 will enable experimentation with multiple integrated advanced technologies and development of new operational concepts. These technologies include a reprogrammable signal generator, an electronically scanned array, flexible and secure signals, increased automation, and use of commercial command and control assets. Technologies matured and knowledge gained from NTS-3 are expected to transition to future generations of GPS constellations.
