| Popis: | This paper presents the reasons for the establishment, activities prior to and after the construction as well as the first results of coordinate time-series of points of the Slovenian combined geodetic network. The so-called zero-order geodetic network is of the highest quality, and since it connects the horizontal and vertical components of the coordinate system, it represents a framework for the realization of a unified national geodetic spatial system. From the establishment on, daily GNSS processing is performed for the analysis of time-series of coordinates of the network points. Currently, the time-series of coordinates confirm the satisfactory quality of equipment, observations and stabilization of stations. The repeatability of the coordinates is at a few-millimetre level for horizontal coordinates and at a five-millimetre level for the heights. However, the current time-series of coordinates allow only the first insight into the stability of the network points. For more definitive conclusions, it will take a few more years to acquire longer time-series of coordinates for identification of the disturbing effects for the particular station. The future activities are related to the inclusion of all satellite GNSS systems and the integration of combined geodetic network’s GNSS stations into the EUREF permanent station network, EPN, which will enable quality and continuous connection of the Slovenian coordinate system with all the ITRS and/or ETRS realizations. |
