    Opis:
    Spatial configuration of DGPS permanent reference station elements has an effect on performance of the entire system. Arrangement of station elements, such as broadcast antenna and reference masts, requires allowance and further linking together number of technical, operational and terrain factors. Some technical and operational factors as a rule are determined by equipment manufacturer, however terrain factors are conditioned by terrain character of the future reference station site. Terrain character is a composition of its surface shape and all geographical features situated within the reference station surroundings. These factors often can cause certain difficulties during recommended elements' arrangement of the planned reference station. This elaboration presents applications of visibility analysis in planning spatial location of reference station GPS antennas. Visibility, or viewshed, analysis is usually available in various computer programs of Geographic Information System environment. It can be performed from any point situated in three-dimensional space of elaboration range. In the case of such elements as permanent GPS antennas, application of visibility analyses solves a problem of their location with allowance of surroundings and geographical features, which can cause limitation of visibility of satellites and occurrence of multipath. By performing this kind of analyses can be determined threedimensional position of GPS antennas, which meets such requirements as recommended horizon visibility.

    Opis:
    Both definition and realization of vertical reference systems require gravity. Relation between height changes and gravity changes is well known in geodynamics on local, regional, and global scale. Consideration of time as additional dimension is needed in the modern vertical and gravity reference systems as well as in processing both levelling and gravity data. Classical vertical and gravity reference systems are briefly presented followed by the discussion of the need of advanced modification of both systems. Geodynamic aspects in creating modern vertical and gravity reference systems were discussed. The role of geodynamics in the realization of vertical and gravity reference systems was presented with emphasizing the key role of metrology.

    Opis:
    The new solution for the Polish geodetic primary GNSS network was created to verify the currently used reference frame (PL-ETRF2000). The new solution is based on more GNSS data (more daily observation sessions included, a longer data timespan, GLONASS observations added) which were processed in a newer reference frame (IGb08) according to up-to-date methodology and using the latest version of Bernese GNSS Software. The new long-term solution (spanning 3.7 years) was aligned to the IGb08 reference frame using a minimum constraints approach. We categorized Polish reference stations into two categories according to their data length. We obtained good agreement of the new solution with the PL-ETRF2000: for most stations position differences did not exceed 5 mm in horizontal, and 10 mm in vertical components. However, for 30 stations we observed discontinuities in position time series, mostly due to GNSS equipment changes, which occured after the introduction of PL-ETRF2000. Position changes due to the discontinuities reached 9.1 mm in horizontal components, and 26.9 mm in vertical components. The new solution takes into account position discontinuities, and in addition also includes six new stations which were installed after the introduction of the PL-ETRF2000. Therefore, we propose to update the currently-used reference frame for the Polish geodetic primary network (PL-ETRF2000) with the new solution. The new solution was also accepted by the EUREF Technical Working Group as a class A solution (highest accuracy) according to EUREF standards.

    Opis:
    ASG-EUPOS is Polish GNSS (Global Navigation Satellite System) Ground Based Augmentation System. The name stands for Active Geodetic Network European Position Determination System. It is multifunctional system of precise positioning consisting of more than 100 GNSS reference stations, which constitutes densification of global IGS (International GNSS Service) and regional EPN (European Permanent Network) GNSS (Global Navigation Satellite System) networks. Data collected on those stations are reference for many surveys (real time or postprocessing corrections - differential technology). ASGEUPOS will fulfill a role of main national geodetic frame and will enable conservation of ETRF (European Terrestrial Reference Frame) in Poland. That is one of the reasons why the system activity has to be monitored and controlled.

    In studies of movement essential element of the correctness of the obtained results is correct identification of the reference base. One method for such identification, referred to as “all-pairs method”, is to examine the insignificance of the mutual displacement of potential reference points in all combinations of pairs. It is a well known exact method of identification, but its use in practice is limited to the study of vertical displacements. In this work we present the possibility of application of this method in the study of horizontal displacements. Numerical example illustrates the calculation procedure of the proposed method.

    Opis:
    This paper presents a concept for the identification of stable reference points used in horizontal control networks, which is based on the lengths of apparent displacement vectors and their mean errors. These vectors and their mean errors are obtained during the process of calculating displacements with free adjustment conditions. It will be shown that the influence of the apparent displacement vectors has a significant effect on the calculation of results. The identification of stable points, using the proposed method, is an integral part of the adjustment process and allows for the interrogation the influence of individual point inclusion or deletion from the reference database, on the values of displacements of controlled points. A detailed process of stable reference points identification is presented using the example of a linear-angular network for a barrage.

    Opis:
    The main purpose of this work is to confirm the possibility of making large-scale orthophotomaps applying unmanned aerial vehicle (UAV) Trimble-UX5. A planned altitude reference of the studying territory was carried out before to the aerial surveying. The studying territory has been marked with distinctive checkpoints in the form of triangles (0.5 × 0.5 × 0.2 m). The checkpoints used to precise the accuracy of orthophotomap have been marked with similar triangles. To determine marked reference point coordinates and check-points method of GNSS in real-time kinematics (RTK) measuring has been applied. Projecting of aerial surveying has been done with the help of installed Trimble Access Aerial Imaging, having been used to run out the UX5. Aerial survey out of the Trimble UX5 UAV has been done with the help of the digital camera SONY NEX-5R from 200m and 300 m altitude. These aerial surveying data have been calculated applying special photogrammetric software Pix 4D. The orthophotomap of the surveying objects has been made with its help. To determine the precise accuracy of the got results of aerial surveying the checkpoint coordinates according to the orthophotomap have been set. The average square error has been calculated according to the set coordinates applying GNSS measurements. A-priori accuracy estimation of spatial coordinates of the studying territory using the aerial surveying data have been calculated: mx=0.11 m, my=0.15 m, mz=0.23 m in the village of Remeniv and mx=0.26 m, my=0.38 m, mz=0.43 m in the town of Vynnyky. The accuracy of determining checkpoint coordinates has been investigated using images obtained out of UAV and the average square error of the reference points. Based on comparative analysis of the got results of the accuracy estimation of the made orthophotomap it can be concluded that the value the average square error does not exceed a-priori accuracy estimation. The possibility of applying Trimble UX5 UAV for making large-scale orthophotomaps has been investigated. The aerial surveying output data using UAV can be applied for monitoring potentially dangerous for people objects, the state border controlling, checking out the plots of settlements. Thus, it is important to control the accuracy the got results. Having based on the done analysis and experimental researches it can be concluded that applying UAV gives the possibility to find data more efficiently in comparison with the land surveying methods. As the result, the Trimble UX5 UAV gives the possibility to survey built-up territories with the required accuracy for making orthophotomaps with the following scales 1: 2000, 1: 1000, 1: 500.

    Opis:
    Rivne Nuclear Power Plant (NPP) is located in western Ukraine. Construction of the station began in 1976. Totally four power generating units are operating on the station. Complicated geological conditions and display of man-made karst led to the need for monitoring of sediments and deformations on Rivne NPP. Since 1984 on the Rivne NPP there were conducted geodetic observations on the conditions of height reference network consisting of nine deep fixed reference points, which are installed in basaltic rocks. Totally 110 cycles of observations were conducted. The heights of fixed reference points were determined by leveling of I-st class. It is necessary to assess the kinematics of the reference height network and implement zoning of station territory according to a speed of inclination of the earth's surface. An average annual rates of displacement which appear as a linear trend weredetermined on the results of measurements for each fixed reference point by the least squares method. Excluding these values the vertical displacements of fixed reference points were derived and only the periodic component that is changing according to the periodic law remained present there. For each fixed reference point it was determined amplitude and optimum oscillation period and the coefficients of regression equations. Using the annual velocity of displacement of fixed reference points it was done the zoning of the Rivne NPP. There were allocated areas, which were characterized by different rates of inclinations and frequency of oscillations.
