52. The global positioning system, relativity, and extraterrestrial navigation
Topic: Time and Frequency
Published: 4/27/2009
Author: Neil Ashby
Abstract: Relativistic effects play an important role in the performance of the Global Positioning System (GPS) and in world-wide time comparisons. The GPS has provided a model for algorithms that take relativistic effects into account. In the future explorati ...

53. Time Measurement
Topic: Time and Frequency
Published: 2/3/2014
Author: Michael A Lombardi
Abstract: An overview of time metrology, with emphasis on time interval measurements, and time synchronization. It covers the evolution of clocks and timekeeping, time scales, the fundamentals of time measurement, and the various time transfer technique used ...

54. Time-domain stabilization of carrier-envelope phase in femtosecond light pulses
Topic: Time and Frequency
Published: 5/7/2014
Authors: Young-Jin Kim, Ian R Coddington, William C Swann, Nathan Reynolds Newbury, Joohyung Lee, Seungchul Kim, Seung-Woo Kim
Abstract: We report a time-domain method of stabilizing the carrier-envelope phase (CEP) of femtosecond pulses. Temporal variations of the pulse envelope and the carrier electric-field phase were separately detected with the aid of intensity cross-correlat ...

55. Towards Timely Intelligence in the Power Grid
Topic: Time and Frequency
Published: 2/25/2013
Authors: YaShian Li-Baboud, Julien Marc Amelot, Dhananjay Anand, Gerard Nordeen Stenbakken, Thomas L Nelson, James Moyne
Abstract: One of the key lessons learned from the 2003 Northeast Blackout in the United States was the need for improved timing. The problem began as an isolated issue, but cascaded through the Northeastern grid. Timely situational awareness would likely have ...

56. Two-Way Satellite Time and Frequency Transfer Using 1 MChip/S codes
Topic: Time and Frequency
Published: 11/16/2009
Authors: Victor Shufang Zhang, Thomas Edward Parker, Demetrios Matsakis, Joseph Achkar, Daniele Rovera, Dirk Piester, Andreas Bauch, Luca Lorini
Abstract: The Ku-band transatlantic and Europe to Europe two-way satellite time and frequency transfer (TWSTFT) operations used the 2.5 MChip/s pseudo-random codes with 3.5 MHz bandwidth until the end of July, 2009. The cost of TWSTFT operation is associated w ...

57. WWVB Radio Controlled Clocks: Recommended Practices for Manufacturers and Consumers (2009 edition)
Series: Special Publication (NIST SP)
Report Number: 960-14-09
Topic: Time and Frequency
Published: 9/8/2009
Authors: Michael A Lombardi, Andrew N Novick, John P Lowe, Matthew J Deutch, Glenn K Nelson, Douglas D Sutton, William C Yates, D. Wayne Hanson
Abstract: Radio controlled clocks represent a true revolution in timekeeping. Clocks that synchronize to NIST radio station WWVB now number in the millions in the United States, and new sales records are being established every year. As a result, many of us a ...

59. yocto-Newton force detection sensitivity using trapped ions
Topic: Time and Frequency
Published: 8/22/2010
Authors: Michael J. Biercuk, Joseph Wright Britton, Hermann Uys, Aaron Vandevender, John J Bollinger
Abstract: Recent experimental advances have shown that it is possible to detect forces arising from electric fields at a level of aN/ {square root}Hz (atto {math equal} 10^u-18^ through coupling of micro or nanofabricated mechanical resonators to a variety of ...
