11. Generation of Ultrastable microwaves via optical frequency division
Topic: Time and Frequency
Published: 6/26/2011
Authors: Tara Michele Fortier, Matthew Steven Kirchner, Jennifer A. Taylor, James C Bergquist, Yanyi Jiang, Andrew D Ludlow, Christopher W Oates, Till P Rosenband, Scott A Diddams, Franklyn J Quinlan, Nathan D. Lemke
Abstract: A frequency-stabilized femtosecond laser optical frequency comb serves as a source of microwave signals having very low close-to-carrier phase noise. Comparison of two independent systems shows combined absolute phase noise of -100 dBc/Hz at an o ...

12. Searching for applications with a fine-toothed comb
Topic: Time and Frequency
Published: 4/1/2011
Author: Nathan Reynolds Newbury
Abstract: Frequency combs, like many ground-breaking technologies, are simple in concept; they results from the spectrum of any regular train of optical pulses. What is remarkable is that this simple picture can be actually realized in a number of different ex ...

13. The SIM Time Network
Topic: Time and Frequency
Published: 3/1/2011
Authors: Michael A Lombardi, Andrew N Novick, J. Mauricio Lopez-Romero, Francisco Jimenez, Eduardo de Carlos Lopez, Jean-Simon Boulanger, Raymond Pelletier, Ricardo de Carvalho, Raul Solis, Harold Sanchez, Carlos Andres Quevedo, Gregory Pascoe, Daniel Perez, Eduardo Bances, Leonardo Trigo, Victor Masil, Henry Postigo, Anthony Questelles
Abstract: The Sistema Interamericano de Metrologia (SIM) is a regional metrology organization (RMO) whose members are the national metrology institutes (NMIs) located in the 34 nations of the Organization of American States (OAS). The SIM/OAS region extends t ...

15. A NIST Disciplined Oscillator: Delivering UTC(NIST) to the Calibration Laboratory
Topic: Time and Frequency
Published: 12/1/2010
Author: Michael A Lombardi
Abstract: The National Institute of Standards and Technology (NIST) now offers a service that provides customers with an oscillator locked to UTC(NIST), the United States national standard for frequency and time. A NIST disciplined oscillator (NISTDO) works b ...

16. Evaluation of a GPS Receiver for Code and Carrier-Phase Time and frequency Transfer
Topic: Time and Frequency
Published: 11/15/2010
Authors: Victor Shufang Zhang, Michael A Lombardi
Abstract: We evaluate a dual-frequency, multi-channel GPS receiver for time and frequency transfer applications. The receiver is able to lock its internal clock to an external reference frequency and synchronize the receiver clock to an external timing signal. ...

17. On-Board GPS Clock Monitoring for Signal Integrity
Topic: Time and Frequency
Published: 11/15/2010
Authors: Marc A Weiss, Pradipta Shome, Ron Beard
Abstract: Navigation signal integrity is paramount for aviation and safety of life services. Hitherto GPS signal anomaly alerting has been provided primarily by ground based augmentations. Significantly improved navigation signal integrity and quality may be ...

18. SIM time scales
Topic: Time and Frequency
Published: 10/27/2010
Authors: Michael A Lombardi, J. Mauricio Lopez-Romero, Nelida Diaz-Munoz
Abstract: This paper presents an analysis of the performance of some of the time scales generated in the Sistema Interamericano de Metrologia (SIM) region. We emphasize the generation of the first international time scale in near real time, the SIM Time scale ...

20. On-Board Signal Integrity for GPS
Topic: Time and Frequency
Published: 9/21/2010
Authors: Marc A Weiss, Pradipta Shome, Ron Beard
Abstract: The elements of a space-based integrity approach are to monitor the signals on-board the satellite, such that signal performance can be maintained well within desired integrity limits. These elements include 1) a system for monitoring multiple atomi ...
