TL;DR: In this paper, very long baseline interferometry (VLBI) is used to compare two optical clocks located in Japan and Italy through the observation of extragalactic radio sources.
Journal ArticleDOI
Further Characterization of the Time Transfer Capabilities of Precise Point Positioning (PPP): The Sliding Batch Procedure
TL;DR: A processing procedure is developed that takes advantage of the improved stability of the phase-connected multiday PPP solutions while allowing the generation of continuous clock time series, more applicable to continuous operation/ monitoring of timing equipment.
Journal ArticleDOI
GNSS interoperability: offset between reference time scales and timing biases*
R. Piriz,Alvaro Mozo García,G. Tobías,V. Fernandez,Patrizia Tavella,Ilaria Sesia,Giancarlo Cerretto,J. Hahn +7 more
TL;DR: The different issues involved in GPS/GIOVE interoperability for positioning and timing, including GGTO (the GPS to Galileo time offset) and timing biases, are analyzed and practical experience and results related to EGGTO are presented.
Journal ArticleDOI
Calibration of galileo signals for time metrology
TL;DR: This paper proposes a procedure to determine the hardware delays of a GNSS receiving station for Galileo signals, once the delays of the GPS signals are known, and shows that the results obtained with this approach or with the ionospheric method are equivalent.
In-orbit performance assessment of GIOVE clocks
P. Waller,F. Gonzalez,J. Hahn,S. Binda,R. Piriz,I. Hidalgo,G. Tobías,Ilaria Sesia,Patrizia Tavella,Giancarlo Cerretto +9 more
TL;DR: In this paper, the authors present the performance assessment of the GIOVE-A and GioVE-B clocks, based on the analysis of the clock behavior as restituted by the Orbit Determination and Time Synchronization (OD&TS) algorithms.
