The permanent GPS stations are particulary important for studying various phenomena because they provide uninterrupted measurements allowing to form the time series of station coordinates. Analysis of GPS solutions time series (GPSSTS) for short meridian baselines were explored in the paper (Kryński and Zanimonskiy, 2000). In our article we intend to extend the analysis of the GPSSTS for baselines of different lengths and azimuths. GPS observation data from the ASG-PL network have been used in the research. The GPSSTS in time and frequecy domain have been analyzed. The spectrums of the GPSSTS with the using coherence function were compared. Moreover, a practical approach to correct any unmodeled effects in GPS baseline solutions that cannot be computed using classical GPS adjustment was presented., Władysław Góral and Daniel Jasiurkowski., and Obsahuje bibliografii
In this work, the set of procedures to prepare the GPS vector solutions time series (VSTSGPS) to spectrum analyses is presented. This preparation is shared on two stages. In the first stage, the breaks filling was processed. This stage was achieved in two steps. Firstly, the breaks filling was computed on the base of time series of other vectors. Secondly, the breaks filling was computed using the interpolation or extrapolation methods. The next stage of VSTSGPS preparing implicated the time series smoothing to remove the impulse noises. After breaks filling and smoothing the VSTSGPS were tested for admission to further analyses., Daniel Jasiurkowski., and Obsahuje bibliografické odkazy
