|Abstract:||The Advanced Space Positioning, Navigation and Timing Branch at the U.S. Naval Research Laboratory (NRL) has conducted research and technology development activities in time and frequency for many decades. These activities have included basic and applied research and development in the areas of advanced navigation satellite technology and precise time and time interval theory and techniques, as well as timing critical communication systems, supporting both the U.S. and international time and frequency communities. NRL has been instrumental in the development of space-borne atomic clocks used in the Global Positioning System (GPS), which has become a vital resource of time and frequency. An overview of the current NRL programs will include GPS space clock life testing and on-orbit analysis, NRL contributions to the GPS next generation time scale, a world-wide nanosecond level time distribution system, and Two-Way Satellite Time Transfer demonstration on a moving platform.|
