CSP - VI INTERNATIONAL TIME SCALE ALGORITHMS SYMPOSIUM
Abstract
As the data rates in military systems increases and as the need for synchronization of data sources becomes more critical, accurate clocks and timescales are becoming increasingly important. This conference will focus on algorithms for timescales, which are optimized averages of atomic clock time and frequency data. Timescales are essential to every application of atomic clocks, ranging from telecommunications to GPS. The symposium objective is to establish the mathematical tools necessary to optimize the extraction of information from time and frequency data so as to facilitate new scientific discoveries and new physical realities. The field is being transformed by new time transfer techniques, new levels of precision, portability, and robustness in frequency standards, and new wide-scale applications of clocks and time scales. Current research topics include measurement data processing, noise and bias identification, prediction, mathematical modeling principals, optimal time scales, applications of highly portable (chip-scale) clocks, the combination of high-precision frequency transfer such as via optical cables or carrier phase two-way satellite time transfer with established time transfer modes, and security. The development of timescales for some of these applications, such as those involving chip-scale clocks and optical fibers,would be of particular interest to ONR since it has provided and is providing considerable support to the development of these very promising devices. Impact on military applications and US Navy:Time scales are an essential element for navigation, particularly in GNSS (GPS, GLONASS, Beidou, Galilee, QZSS) because these systems rely on accurate time references and they develop their internal system times based on time scale algorithms. In the conference an important number of presentations will be dedicated to these topics.A session of the conference will be dedicated to the state of the art of the different GNSS systems and invited talks are foreseen both for the Tutorials and for the Symposium to present the new time scale algorithms used for navigation. Particular attention will be put on the mathematical tools used to improve the time scale performance.
