Opis:
In this paper, there are presented the main reasons and results of changes in maritime navigation. The following issues are discussed: substance of maritime navigation; the main reasons of changes in maritime naigation; integration of the ship`s navigation process and its results; the growing necessity of supervising all the human activities performed at sea and the main results from the channges in maritime navigation. This paper should be considered as further precising and developing the authors` considerations and conclusions presented in their earlier works.

Opis:
Position coordinate measurements are an intrinsic feature of navigation. These measurements include points on vessel's trajectory and trajectory derivatives: speed vector and acceleration vector. Due to the fact that systematic and random errors occur in both mathematical model of the navigation process and in specific measuring models, there is no full congruity of the results of measurements performed by various navigational instruments and systems. This work attempts at comparing trajectories, speeds and accelerations obtained by these' navigational devices and systems. The results may be used in examining the measurement reliability and the performance correctness of navigational equipment and system. The comparison of various sources of information also enables detection and identification of systematic errors. Consequently, mathematical models of particular phenomena and processes can be verified.

Opis:
Dead reckoning is one of the oldest methods of ship's position deternrination in sea navigation. Its advantages ara autonomy and possible integration with other position determination methods, in particular with the statistical model for working out measurements of navigational paranieters. Dead reckoning makes use of basic navigational instruments that every ship is equipped with, i.e. the compass and the log. Basieally, the method pertains to calculating ship's coordinates for a defined moment of time by means of the integration of ship's speed and acceleration in the case of analogue measurements, or by calculating the increment of the coordinates from differenlial equations in the case of discrete measurements of speed or acceleration. The present position is determined as a sum of the coordinates increments.

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.

Opis:
In this paper, an attempt has been made to present the most important issues regarding the maritime navigation affairs in the European Union. The authors' main objective is to show the place and relations of maritime navigation to the basie maritime affairs and activities, especially maritime navigation activities and affairs. Authors have tried to show the main institutions and services of the European Union dealing with the maritime navigation affairs as well as characterize the activities of these Directorates'-General of the EU whose activities are very closely connected with the maritime navigation affairs.

Opis:
Electronic Chart Display and Information System became nowadays the main equipment for presentation of marine ship's position and perform of basic navigational tasks. There are new information systems under development like Marine Decision Support System. All systems require constant information about position of own ship and other objects in the vicinity. Information is gathered from onboard navigational systems. Integrity of that information is crucial for taking its full advantage and presentation in onboard information systems.

Opis:
The sequential method of integrating navigartional parameters obtained from non-simultaneous navigational measurements is presented. The proposed algorithm of position coordinates estimation is general and includes two modes of data processing - from simultaneous and non-simultaneous measurements. It can be used in hybrid receivers of radionavigation systems integrating non-homogeneous position lines or in integrated navigation systems, particulary in receivers combining the measurements of various satellite navigation systems.

Opis:
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.
