Opis:
This paper draws attention to the lack of information as to how early North Sea sailors navigated, particularly during the one thousand year period that followed Roman times. The lead and line was the only navigational aid available for most of this period, but there is little recorded as to whether it was used simply for ensuring a ship or boat had enough water to proceed or whether, together with the knowledge it provided of the nature of the sea bed, it was used as a more positive position fixing device. The author would appreciate any information relating to navigation techniques used during this period.

Opis:
Seafaring is one of the oldest documented human activities, with a rich heritage created by generations of seamen. The first boats were developed several thousand years ago, based on primitive principles, and they were probably not suitable for other than simple purposes. Analyzing the history of boat building shows a gradual change in designs. These design changes were most likely due to improvements, related to different aspects of experiences undergone; the changing activity purposes of the boats; and the continual resolution of a conflict between what is possible and what is desired. Nevertheless, design changes and different improvements were developed in a relationship between experiences gained by sailors and shipbuilders. Therefore, the development of seafaring was probably, both directly and indirectly, based on the experiences of sailors who had gained knowledge of the sea. The first written documentation to support the relationship between sailors and knowledge of the sea is in the Old Testament of the Christian Bible, approximately 950 years before Christ. King Solomon of Israel formed an alliance with the Phoenician king of Tyre, Hiram 1, because he needed the Phoenicians’ ships and naval expertise. “And Hiram sent his servants with the fleet, sailors that have knowledge of the sea, along with the servants of Solomon” (1. King IX – 27). The phrase “sailors with knowledge of the sea” correlates with a partial core of seamanship science. The science of seamanship is a multi-dimensional expression, which concerns seamen’s complete competence in sailing and operating a ship. The purpose of this article is to discuss the origin and development of the ship-operating aspects of seamanship and shed light on aspects of the development and challenges regarding exercise of seamanship competence-related maritime education and training (MET).

Opis:
The authors of the article consider the stone labyrinths as solar calendars. In the center of these structures there are usually already installed gnomons – vertical objects that give shade. Midday shadow points to north, and the change of its length during a year is correlated with the diameter of the arcs of the labyrinth. Points of sunrise / sunset at the equinoxes and solstices are very often fixed in the pattern of the labyrinth, as well as the beginning of the annual cycle. In general, patterns of labyrinths are of the same type, the differences reflect the regional characteristics of illumination, the differences in latitude and topography (shape of the horizon). The uniformity of the technology and the location on the waterways give an opportunity to consider stone labyrinths as ancient elements of local and regional navigation networks.

Opis:
W artykule przedstawiono historyczny zarys znaczenia transportu śródlądowego w systemie transportowym Polski. Wykazano, że od lat osiemdziesiątych ubiegłego wieku obserwuje się stały regres znaczenia tej gałęzi transportu w Polsce. Zasadniczy wpływ na taki stan, prócz zmian w strukturze podaży ładunków, ma degradacja dróg wodnych, a szczególnie Odrzańskiej Drogi Wodnej (ODW). Droga ta, która w przeszłości spełniała wymogi klasy III, obecnie na wielu odcinkach ma tylko parametry klasy II. Znaczącym elementem rozwoju śródlądowego transportu wodnego jest dostosowanie się tej gałęzi do nowych istniejących i rozwijanych technologii transportu, a zwłaszcza do transportu kontenerów. Transport ten jest możliwy nawet w obecnie występujących warunkach nawigacyjnych przy wykorzystaniu istniejącej floty.
The article presents a historical outline of the importance of inland waterway transport in the Polish transport system. It has been shown that since the 80s of the last century steady regression in that sector of transport in Poland has been noticed. A major impact on the state, except for changes in the structure of the goods supply, has the degradation of waterways, especially the Oder Waterway. The waterway, which in the past met the requirements for Class III, now in many places meets only Class II. A significant element in the development of inland waterway transport, is to adapt the system to existing and new transportation technologies developed on a global scale, particularly the transport of containers. Containers transport is possible even with the currently existing navigation conditions, using the existing fleet.

Opis:
The article discusses the concept of time in navigation, especially in marine navigation, as well as selected time measures, among others: Greenwich Mean Time (GMT), Universal Time Coordinated (UTC), International Atomic Time TAI (Temps Atomique International), GPST (Global Positioning System Time) eLoran Time and interrelation between these measures. Understanding how time is involved in navigation, and using it, is one of the navigator's most important duties. Nowadays we have satellite navigation to help us know where we are. These satellites contain several very precise and accurate clocks, because time and location are completely and totally inter-related in satellite navigation. There is growing interest internationally concerning the vulnerability Global Navigation Satellite Systems (GNSS) to natural and man-made interference, plus the jamming and spoofing of their transmissions. These vulnerabilities have led to a demand for sources of resilient PNT (Positioning, Navigation and Timing) [16], including a robust means of distributing precise time nationally and internationally.

Opis:
The goal of the study was to examine ice cover conditions that accompanied the passage of convoy of seven Polish vessels from Europe to the Far East in year 1956, which initiated an international commercial shipping transit. Several different sources of information on the state of ice cover in the Arctic were used in this study. Ice conditions (decisive for ability of a merchant vessel or icebreaker to cross the route) during the following navigational seasons in most of the NSR areas showed extremely divergent results - from the most favorable to the most difficult and vice versa. Existing in years 1940-1957 ice cover conditions and shipbuilding technologies did not guarantee a successful transit passage in one navigation season. The Soviet Union used icebreakers that were not able to lead vessels in heavy ice conditions that occurred in 1950s. The NSR Administration used passive strategy ? waiting for improvement of ice conditions - instead of forcing heavy ice. Passive strategy of navigation through the NSR included wintering and continuation of passage next year when ice conditions improved. Annual variability of ice conditions approximated by third degree polynomial line showed trends well. However, the high annual anomalies of ice conditions in relation to trend line did not allow for effective forecasts on particular sections of the NSR in next navigation season.

Opis:
The operating zone of a radio navigation system is one of its main operating features. It determines the size of a water body in which the system can be used, while guaranteeing vessels’ navigation safety. The DGPS system in the LF/MF range is now the basic positioning system in coastal waters around the world, which guarantees not only metre positioning accuracy, but it is also the only one to provide navigators with signals on positioning reliability. This paper describes and summarises over twenty years of studies dealing with the operating zone of the Polish DGPS reference station network. This paper is the fifth in a series of publications whose aim was to present in detail the process of installation, testing and long-term evaluation of the navigational parameters of the Polish DGPS system, launched in 1995. This paper includes the theoretical foundations of determination of the Dziwnów and Rozewie DGPS reference station operating zones in the years 1995-2018. Moreover, it presents the measurement results for the signal levels and the results of their analyses, which determine the station operating zones.

Opis:
The paper presents engineering interests of Isaac Newton, including some of his technical inventions. So far, this topic has not been studied in a broader manner and in more depth. This article discusses Newton’s youthful passions against the backdrop of the so-called mathematical magic literature. His two inventions, i.e. variants of the reflecting telescope and the marine octant are also discussed. Finally, an example is provided of the involvement of the author of Principia in a discussion around the steam engine and the ship powered by such engine designed by Denis Papin.
Artykuł przedstawia zainteresowania inżynierskie Isaaca Newtona, w tym niektóre z jego wynalazków technicznych. Temat ten nie doczekał się jak dotąd szerszego i pogłębionego opracowania. W artykule poruszono młodzieńcze pasje Newtona na tle literatury z zakresu tzw. magii matematycznej. Omówiono także dwa wynalazki Newtona – wariant teleskopu zwierciadłowego i oktant morski. Na koniec został przytoczony przykład zaangażowania autora Zasad w dyskusję nad projektem technicznym maszyny parowej i napędzanego przez nią statku autorstwa Denisa Papina.
