Limits on GPS Carrier Phase Time Transfer

Author(s)
Marc A. Weiss
The stability of differential delays between Global Navigation Satellite receivers is critical for time and frequency transfer. We study the limit of this

Phase-lock Loops in Vibration Environments

Author(s)
Archita Hati, Craig W. Nelson, David A. Howe
A popular scheme for achieving low phase noise across a large range of offset frequencies is to employ an oscillator at an output frequency with low far-from

Two-Way Satellite Time and Frequency Transfer Using 1 MChip/S codes

Author(s)
Victor S. Zhang, Thomas E. Parker, Demetrios Matsakis, Joseph Achkar, Daniele Rovera, Dirk Piester, Andreas Bauch, Luca Lorini
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

Novel, All-Digital Phase Measurement System for Time Scales

Author(s)
Stefania Romisch, Thomas E. Parker, Steven R. Jefferts
A novel, all-digital phase measurement system, to be utilized as part of the NIST Time Scale at NIST in Boulder, CO is presented. The system is used to compare

The feasibility of developing a network of telescopes to monitor the composition of the nighttime atmosphere using stellar spectrophotometry is explored

A Novel Wafer-plane Dosimeter for EUV Lithography

Author(s)
Steven E. Grantham, Charles S. Tarrio
Extreme Ultraviolet Lithography (EUVL) incorporates 13.5 nm light for patterning wafers and requires in-situ wafer-plane dosimetry that can be tailored to the

Uncooled, Millimeter-Scale Atomic Magnetometers with Femtotesla Sensitivity

Author(s)
John E. Kitching, Svenja A. Knappe, William C. Griffith, Jan Preusser, V Gerginov, Peter D. Schwindt, Vishal Shah, Ricardo Jimenez Martinez
We summarize recent results at NIST to develop high-performance yet highly miniaturized magnetic sensors based on atomic vapors confined in microfabricated

Creating a web-scale video collection for research

Author(s)
Paul D. Over, George M. Awad, Alan Smeaton, Colum Foley, James Lanagan
This paper begins by considering a number of important design questions for a web-scale, widely available, multimedia test collection intended to support long
