Practical methods of the interpolation of TWSTFT data and computation of the stability

Abstract

Two-way satellite time and frequency transfer (TWSTFT) data are typically recorded on Tuesday and Friday in Asia Pacific TWSTFT network. This produces an irregularly spaced time series that affect the system analysis. Based on the investigation of the effect of uneven data spacing on the computation of stability, the method of interpolation of TWSTFT data as well as the computation method of stability of TWSTFT system are designed in this paper. This paper' purpose is to suggest methods and corrections which may be applied to data in order to obtain a more accurate assessment of the underlying time stability.
