Opis:: Introduction to using EGNOS system made possible determining of position in navigation and measurement applications. High accuracy of determined position, at precision of system DGPS level, allowed for taking advantage of that system in hydrographic measurements. In article are presented observations from signals transmitted by EGNOS system satelIites in 2005, in the middle of operation activating, to protecting of hydrographic measurements at sea and inland areas.

hydrographic survey
Opis:: Depth measurement, as an element of hydrographic surveys, is realised in local reference system connected with a hydrographic vessel. Taking echosounder transducer's draught into consideration enables determination of the distance between water surface and the bottom. Sea level is changeable, especially in tide areas, even during hydrographic surveys. This fact created the necessity to work out many vertical reference systems. In tideless areas MSL - Mean Sea Level is generally used. Alternative for many vertical reference systems can be determination of the depth on reference ellipsoid using geopotential model of the Earth. This solution enable use of positioning systems for depth measurements and reduction of heaving.

Tytuł:: Dteremnination of spatial orientation of sounding vessel using floating core fluxgate
Autorzy:: Makar, A.
Powiązania:: https://bibliotekanauki.pl/articles/224685.pdf
Data publikacji:: 2009
Wydawca:: Politechnika Warszawska. Wydział Geodezji i Kartografii
Tematy:: nawigacja morska

bathymetric survey
Opis:: Determination of spatial orientation of sounding vessel is an essential problem from determination of acoustic wave reflection points in geodesic bathymetric surveys radiated by an echosounder point of view. Pitching, rolling and yawing as a result of wind, wavy motion and vessel movement determine the outlet angle of acoustic wave, trajectory of acoustic ray as a result of refraction, location of reflection point and determined depth on the basis of the distance between the transducer and reflection point measured by the echosounder. In the paper possibilities analyse of floating core fluxgate's application for determination of spatial orientation of sounding vessel have been presented. Compensation of pitching and rolling have only been presented because of sensor limitation.

Słupsk Bank
Opis:: The Słupsk Bank, formerly knows as the Stolpe Bank (after the former German name Stolp of the now Polish city of Slupsk) is a bank situated 16 miles northward of Ustka, is about 24 miles long east and west and 10 miles broad. It has on the greater partof it general depths of 10 to 18 m, sand; the shoalest part is the northwestern, where there are several patches with from 8 to 9 m water, and at the western end, where there is a depth of 10 m. On the southeastern edge of the bank the water deepens suddenly to 29 and 33 m and on the other edges gradually. Because of long distance to the coast and large area, hydrographic surveys are carried out by large hydrographic vessels in 24H system. Results of hydrographic surveys of the part of Slupsk Bank have been presented.

Opis:: Thermovision is known physical phenomenon based on emission of electromagnetic fields by each body with temperature above than absolute zero. This emission is called, for the sake of the wave, infrared emission and for the sake of its property - thermoemission. Intensity of thermoemission is proportional to the temperature of the body. So, during measurement of infrared emission of the body there is possible to indirect measure its temperature. Characteristic application of the thermovision can be usage of thermoemission radiated by moving object for its localization. In this paper the concept of passive navigational system working on the basis of thermovision cameras placed on the land are used for detection and tracking objects emitting infrared waves.

Wisłoujście Fortress
Opis:: In the close vicinity of the Westerplatte peninsula lies a unique fortification monument - the Wisłoujscie Fortress. The name Wisłoujście (the mouth of the Vistula) dates back to the time when the Vistula had its estuary north of the Wisłoujście Fortress. The site was an area of strategic importance as it gave control of ships moving into and out of Gdańsk. The Fortress is surrounded by shallow water. Hydrographic surveys are important because of navigation safety of small ships and yachts and they are difficult because of limited maneuverability of sounding vessel and limitations in positioning. Results of hydrographic surveys of Wisłoujście Fortress have been presented.
