Keywords: kinematic reference coordinate system, additive forecast model of GNSS and DORIS time series

Abstract

This paper is devoted to our studies of the current kinematic terrestrial reference system in Uzbekistan. The additive model is used to obtain the parameters of the stations’ coordinate time series predicted and to investigate ways to construct these time series forecast models in future. The KIT3 (GNSS), KIUB and KIVC (DORIS) Kitab station coordinate time series have been decomposed (in their trend, seasonal and stochastic components), and their forecast models are constructed. The forecast model of the KIT3 and KIUB station coordinate time series explains 99 % of the time series total variation for the horizontal coordinates and about 40 % for the vertical coordinates. The forecast model for the height component of the new DORIS KIVC station has shown a model confidence level of about 70 % which allows us to conclude that it is possible to continue our studies of this station’s data in combination with hydrological (for example, GRACE), seismic and gravimetric measurements in order to build a detailed geophysical station model.

terrestrial reference system in Uzbekistan. The additive model is
used to obtain the parameters of the stations’ coordinate time series
predicted and to investigate ways to construct these time series
forecast models in future. The KIT3 (GNSS), KIUB and KIVC (DORIS)
Kitab station coordinate time series have been decomposed (in their
trend, seasonal and stochastic components), and their forecast models
are constructed. The forecast model of the KIT3 and KIUB station
coordinate time series explains 99 % of the time series total
variation for the horizontal coordinates and about 40 % for the
vertical coordinates. The forecast model for the height component of
the new DORIS KIVC station has shown a model confidence level of
about 70 % which allows us to conclude that it is possible to
continue our studies of this station’s data in combination with
hydrological (for example, GRACE), seismic and gravimetric
measurements in order to build a detailed geophysical station model.
