Application of the Dynamic Allan Variance for the Characterization of Space Clock Behavior
TL;DR: The dynamic Allan variance (DAVAR) is extended to the case of a time series with missing data, and the presence of periodic behaviors, two common phenomena in space clocks are analyzed.
Journal ArticleDOI
The In-Orbit performances of GIOVE clocks
TL;DR: The behavior and performances of the clock technologies on board both spacecrafts has been investigated and analyzed in terms of operation, frequency stability, and clock prediction error after more than 3 years of operation for GIOVE-A and almost one year for GioVE-B.
Journal ArticleDOI
Estimating the Allan variance in the presence of long periods of missing data and outliers
Ilaria Sesia,Patrizia Tavella +1 more
TL;DR: This work proposes an estimation algorithm and its implementation in a robust software code (in MATLAB® language) able to estimate the AVAR in the case of missing data, unequally spaced data, outliers, and with long periods of missing observation so that the Allan variance estimates turn out unbiased and with the maximum use of all the available data.

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.

TL;DR: In this paper, the first recalibration of TWSTFT links during a campaign involving six European time institutes was reported, where a portable ground station assembled and operated by TUG/Joanneum Research, Graz, that visited the sites of INRIM, NPL, OP, PTB, SP, and VSL, travelling a total distance over 7000 km during a three-week period in October/November 2005.
