  Hydrographic surveys, in accordance with the International Hydrographic Organization (IHO) S-44 standard, can be carried out in the following five orders: Exclusive, Special, 1a, 1b and 2, for which minimum accuracy requirements for the applied positioning system have been set out. They are as follows, respectively: 1, 2, 5, 5 and 20 m, with a confidence level of 95% in twodimensional space. The Global Navigation Satellite System...

  This article describes the design of the unmanned surface vessel (USV) and the algorithms for planning the trajectories to be followed on measurement missions. The algorithms take account of the dynamically varying impacts of external forces (wind and surface current) on the vessel's motion. Feedback loops enable the counteraction of external factors that cause disturbance to the desired trajectory. The sensors installed on the...

  Nowy model echosondy zaprojektowanej specjalnie dla instytucji administrującymi śródlądowymi drogami wodnymi, sztucznymi i naturalnymi zbiornikami oraz morskimi wodami przybrzeżnymi jest opisany. Podstawowym wymogiem wynikającym z sondażu wód płytkich jest pomiar możliwie najmniejszych głębokości. Przez zastosowanie oddzielnych przetworników (nadawczego i odbiorczego) i ich wytłumienie oraz przez wprowadzenie układu TVG o dużej...

  - Year 2017

  The article presented problems of fragmentation of hydrographic big data into smaller subsets during reduction process. Data reduction is a processing of reduce the value of the data set, in order to make them easier and more effective for the goals of the analysis. The main aim of authors is to create new reduction method. The article presented the first stage of this method – fragmentation of bathymetric data into subsets. It...
