The performance of bathymetric measurements by traditional methods (using manned vessels) in ultra-shallow waters, i.e., lakes, rivers, and sea beaches with a depth less than 1 m, is often difficult or, many cases, impossible due to problems related safe vessel maneuvering. For this reason, the use shallow draft hydrographic Unmanned Surface Vessels (USV) appears provide promising alternative method for performing such measurements. This article describes modernisation USV switch from manual...

Abstract A possibility of utilising the GPS system for navigation and transport are fundamentally dependent on accuracy in positioning. Two fundamental factors decisive its value values User Range Error (URE) Dilution Precision (DOP), strictly related to number satellites forming constellation. The nominal constellation consists 24 units which gives a identification coordinates all over globe. In last few years, however, was much higher, URE has been constantly increasing. authors paper try...

A tombolo is a narrow belt connecting mainland with an island lying near to the shore, formed as result of sand and gravel being deposited by sea currents, most often created natural phenomena. However, it can also be caused human activity, case Sopot pier—a town located on southern coast Baltic Sea in northern Poland (φ = 54°26’N, λ 018°33’E). As result, seafloor rises constantly shoreline moves towards sea. Moreover, there additional disturbing phenomenon consisting rising covering over...

The human impact on the ecosystem has been particularly evident in last century; it transforms Earth’s surface an unprecedented scale and brings about irreversible changes. One example is oceanographic phenomenon known as a tombolo, i.e., narrow belt connecting mainland with island lying near shore formed result of sand gravel being deposited by sea currents. contributes to increase biogenic substance content littoral zone, which leads increased cyanobacteria blooming summer period....

The analysis based on geospatial data from different measurement systems now constitutes a complex numerical and practical enterprise. dynamic development of modern technologies enables rapid precise acquisition such data.

This issue visible during implementation hydrographic geodetic surveys...

In navigation, the Twice Distance Root Mean Square (2DRMS) is commonly used as a position accuracy measure. Its determination, based on statistical methods, assumes that errors are normally distributed and often not reflected in actual measurements. As result of widespread adoption this measure, positioning navigation systems overestimated by 10–15%. paper, new method presented for determining system reliability model where system’s operation failure statistics referred to life times. Based...
