<abstract xmlns="http://www.w3.org/1999/xhtml"> An essential aspect of the safety of navigation is avoiding collisions with other vessels and natural or man made navigational obstructions. To solve this kind of problem the navigator relies on automatic anti-collision ARPA systems, or uses a geometric method and makes radar plots. In both cases radar measurements are made: bearing (or relative bearing) on the target position and distance, both naturally expressed in the polar coordinates system originating at the radar antenna. We first convert original measurements to an ortho-Cartesian coordinate system. Then we solve collision avoiding problems in rectangular planar coordinates, and the results are transformed to the polar coordinate system. This article presents a method for an analysis of a collision situation at sea performed directly in the polar coordinate system. This approach enables a simpler geometric interpretation of a collision situation </abstract>

Diversity of Photogrammetric Approaches for Multi-Purpose Applications

<abstract xmlns="http://www.w3.org/1999/xhtml"> In the area of carbonate or karst Dinarides, besides the dominant carbonate rocks and subordinate clastics, in more places more significant mass of chemical sediments can be found, represented by gypsum and anhydrite. As chemical sediments are specifically lighter than overlying rocks, they have been, during the long geological history, trying to achieve isostatic equilibrium, or get out on the ground surface. In recent times, in areas with chemical sediments, a larger tectonic activity is noted than in the wider environment. This is certainly reflected in increased vertical and tangential displacements along major faults in relation to the surrounding area, which are built mainly of carbonate deposits. Determining the amount of movement of diapiric bodies, as absolute and relative, using the most modern surveying methods, precisely would assist the understanding of the tectonic movements and recent structural relations in a wider area</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> The air transport requires certificate of ground and deck devices, systems and adequate procedures. However applied geodetic techniques and measuring technologies depend on taken undertakings. If one should precisely put standard ground systems and the navigational assistance are overbalancing static geodetic techniques and measuring technologies. However operational activity, depending on the phase of the flight a real requires applying geodetic techniques and measuring Jechnologies time”. As part of conducted air tests they made the validation of four fundamental parameters (accuracy, credibility, availability, continuity) of satellite EGNOS, GNSS signals, made as part of European projects: “Support to the EGNOS APV Operational Implementation - APV MIELEC”, air tests enabled to draw right procedures up and to apply satellite signals in the air transport. Details will be presented in the following article. </abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> This paper presents results of two experimental cycles of measurements performed with the use of the terrestrial laser scanner Z+F IMAGER 5006h and the reflectorless tacheometer Leica TPS 1202. These tests aimed at determination of metric properties of surveying instruments, which are used for reflectorless distance measurements and which are often applied to project the geometry of objects. In the course of research works issues influencing the reflection of a laser beam by the measured surface, as well as their influence on the data quality. In order to analyse metric properties of applied instruments, levelling rods were used as test fields of geometrically specified division. It was stated basing on the performed analyses, that the influence of the incidental angle of a laser beam on the accuracy of reflectorless measurements is included within the limits of the error of distance measurements of a given instrument. However, the uniform trend of increasing differences between measured values and the nominal value may be noticed, together with the increase of the incidental angle of the axis of collimation on the measured surface of the test field. </abstract>

The Attempt to Use Levelling Rods for Testing Metric Properties of Surveying Instruments, Which are Used for Reflectorless Distance Measurements

<abstract xmlns="http://www.w3.org/1999/xhtml"> 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 </abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> This paper presents developed method of a posteriori optimization of measurement results of active geodesic monitoring networks with taking into account the parameters of accuracy and reliability. Filtering the measurement results of active geodetic monitoring networks is in out of order exclusion vectors with maximum corrections, which is determined from successive iterations of network adjustment. After each iteration it’s determined the mean square error of unit weight and the parameter of network reliability. Sifting vectors with maximal errors leads to accuracy improving and reliability deterioration of network. Using entropy approach is defined group of vectors in which the value of accuracy and reliability is optimal. Using the developed method performed a posteriori optimization of active precision geodesic monitoring network of the Dnieper, Dniester and Kanev HPP. The represented method can also be used for the optimization of any active geodesic monitoring networks with large quantity of redundant measurements</abstract>
