Time : from Earth rotation to atomic physics by Dennis D McCarthy( Book )

13 editions published in 2009 in English and held by 180 WorldCat member libraries worldwide

"Filling the need for a book that presents the current technology as well as the underlying historical and physical background, this publication informs scientists, engineers, and those interested in the foundations of modern timekeeping how precise time and frequency are made available for modem-day use. The authors draw on their longstanding research experience with timekeeping and high-precision measurements to describe the discovery of the irregular motions of the Earth, the development of mechanical and atomic clocks, the introduction of dynamical timescales, and the development of the study of the Earth's orientation in space. Also discussed are astronomical and satellite observations used to improve solar system dynamics and Earth kinematics along with the applications of the theory of relativity to the topics of timekeeping and time transfer."--Jacket
Polar motion : historical and scientific problems by IAU Colloquium( Book )

4 editions published in 2000 in English and held by 93 WorldCat member libraries worldwide

Annotation The nonprofit Astronomical Society of the Pacific (ASP) publishes the Conference Series Proceedings as part of its century-old mission to provide resources for astronomers and advance the science of astronomy. Since 1988, the ASP has published the proceedings of astronomical workshops, meetings, colloquia, and symposia to meet the community's demand for affordable, high-quality volumes on current topics in the rapidly expanding fields of astronomy and astrophysics. Since 1998, the Society has also served as publisher for the International Astronomical Union (IAU), adding their Symposia, Highlights, and Transactions to our growing list of publications. For most rapid delivery of each volume, we encourage libraries and astronomy departments to place a Standing Order for the ASP Conference Series and/or the IAU Publications. Standing Orders are shipped directly from the printer and customers receive volumes at the same discounted rates as ASP members (approximately 25-35 ASP volumes each year and/or 5 IAU Symposia). Please refer to the order form to take advantage of this time-saving offer. We encourage all professionals who are sponsoring conferences, workshops, or colloquia to inquire about publishing these proceedings with the ASP. We provide quality volumes at less than half the price of comparable titles from other major publishers, ensuring that the publication will be available to a wider audience of budget-conscious scientists. From a meeting held at Cagliari, Italy, 27-30 September 1999
What time is it? by Judith Grey( Visual )

2 editions published in 2009 in English and held by 67 WorldCat member libraries worldwide

Do we really know what time it is? CERN physicist Professor Brian Cox (and author of E=mc2) unlocks the secrets of time in this entertaining and informative program. His journey starts with the Sun, our historical dictator of time, but Brian discovers that the world doesn't always spin like clockwork -- in fact, it flutters, like an irregular heartbeat. In his search for a more reliable way to tell the time, he experiences the physical definition of a second with a cesium atomic clock, then jets across the Atlantic to discover that time can speed up or slow down depending on how near an object is to a strong gravitational field. Still looking for answers, he consults modern ideas like string theory and quantum mechanics that are pointing the way to future breakthroughs. Includes public performance rights

IERS conventions (2003) by International Earth Rotation and Reference Systems Service( Book )

3 editions published in 2004 in English and held by 6 WorldCat member libraries worldwide

This document is intended to define the standard reference systems realized by the International Earth Rotation Service (IERS) and the models and procedures used for this purpose. It is a continuation of the series of documents begun with the Project MERIT Standards (Melbourne et al., 1983) and continued with the IERS Standards (McCarthy, 1989; McCarthy, 1992) and IERS Conventions (McCarthy, 1996). The current issue of the IERS Conventions is called the IERS Conventions (2003). When referenced in recommendations and articles published in past years, this document may have been referred to as the IERS Conventions (2000). All of the products of the IERS may be considered to be consistent with the description in this document. If contributors to the IERS do not fully comply with these guidelines, they will carefully identify the exceptions. In these cases, the contributor provides an assessment of the elects of the departures from the conventions so that its results can be referred to the IERS Reference Systems. Contributors may use models equivalent to those specified herein. Products obtained with different observing methods have varying sensitivity to the adopted standards and reference systems, but no attempt has been made in this document to assess this sensitivity. The reference systems and procedures of the IERS are based on the resolutions of international scientific unions. The celestial system is based on IAU (International Astronomical Union) Resolution A4 (1991). It was officially initiated and named by IAU Resolution B2 (1997) and its definition was further refined by IAU Resolution B1 (2000). The terrestrial system is based on IUGG Resolution 2 (1991). The transformation between celestial and terrestrial systems is based on IAU Resolution B1 (2000)

Evolution of time scales by Dennis D McCarthy( Book )

2 editions published in 2006 in English and held by 1 WorldCat member library worldwide

Time scales have continued to evolve to meet the developing needs of users in modern times. Fifty years ago time based on astronomical observations of the Earth's rotation was sufficient to meet the needs for time, both civil and technical. During that 50-year interval, however, not only have these scales been expanded, but the advent of practical atomic clocks has led to the development of time scales based on atomic frequency transitions. In addition, the development of modern space techniques and the improvement in observational accuracy by orders of magnitude have led to the improvement of the theoretical concepts of time and the resulting relativistic definitions of time scales. The following sections provide a brief description of the chronological development of time scales since the middle of the 20th century: Mean Solar Time, Universal Time (UT), Ephemeris Time (ET), Atomic Time, Coordinated Universal Time (UTC), Dynamical Time Scales, and the Future of Time Scales
The leap second : its history and possible future by Robert A Nelson( Book )

Evolution of timescales from astronomy to physical metrology by Dennis D McCarthy( Book )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

"Astronomy has provided a means to mark the passage of time throughout history. One of the repeating phenomena that makes this possible is the Earth's rotation. The basic variability in its rotational speed, however, makes astronomical techniques unsuitable for timekeeping with the precision required for modern applications. Physical metrology from the first mechanical clocks to the most sophisticated atomic standards of today has assumed a growing role in timekeeping. Along with this progress in technology, more sophisticated concepts of timescales have appeared to take advantage of those improvements."
The Definition of UTC( )

1 edition published in 2000 in English and held by 0 WorldCat member libraries worldwide

The current definition of Coordinated Universal Time (UTC) is related to the unpredictable, variable rotation rate of the Earth. This is accomplished by irregular insertions of leap seconds, which create unpredictable discontinuities in the UTC. With the increasing importance of a continuous, uniform time scale for users, it is appropriate to re-examine the current definition of this time scale. There are several ways to address this problem, and it is appropriate that the International Astronomical Union (IAU) establish a working group to investigate the continuing need for leap seconds and possible changes in the definition of UTC
Panel Discussion on GNSS Interoperability( )

1 edition published in 2005 in English and held by 0 WorldCat member libraries worldwide

This panel discussion on GPS SIGNALS GNSS INTEROPERABILITY CHALLENGES AND OPPORTUNITIES focuses on the following topics: A. Ensuring Radio Frequency (RF) compatibility - June 2004 US-EU agreement for GPS-Galileo + follow-on working groups; - Ongoing bilateral discussions between United States and other nations/organizations for QZSS, GLONASS, SBAS, etc.; B. Enhancing interoperability Incorporation of system time offset messages in navigation data for new civil/military signals. Are there other inter-system messages that would be useful? Increasing commonality in messages, signal structures, services. Is dissimilarity, in some cases, more beneficial?; C. Spectrum protection. As new GPS signals and Galileo come online, people need to be ensured that they will continue to enjoy all capabilities that they are enjoying today from GPS. The Europeans are investing billions in Galileo, and they would like to make sure that they are not going to be interfered with by GPS. A lengthy document attached to the US-EU agreement in June 2004, by reference, describes the methodology that should be used to ensure that the two systems are RF-compatible. Similar documents are being used by the U.S. now in bilateral discussions with Japan for QZSS, as in other bilateral discussions. As far as interoperability goes, there is a need to provide time offsets between Galileo system time and GPS time. Back in October, a document ICD-GPS-200D was approved by the GPS Joint Program Office, which is the new baseline document, not only for the new L2 civil signal, but also for the L1-L2P (Y) Code and L1-C/A code. This document describes all the messages that will be used for L2C
