Na przestrzeni ostatnich lat nastąpił bardzo dynamiczny rozwój bezzałogowych jednostek, które są wykorzystywane niemal w każdej dziedzinie życia. W artykule przedstawiono możliwości wykorzystania UAV w szeroko pojętej nawigacji, jak możemy korzystać z dronów w środowisku morskim, obserwować porty, prowadzić misje na morzu, jak robić mapy dna morskiego i jakie korzyści z dronów ma środowisko wojskowe.

Over the past years, there has been a very dynamic development of unmanned aerial vehicles that are used in almost every area of life. The article presents the possibilities of using UAVs in the broadly understood navigation, how to use drones in the sea environment, observe ports, conduct missions at sea, how to make seabed maps and how drones are used in the army.

In this article the authors propose a change in approach when providing information included in maneuvering documents on the squat effect of a ship. The development of ships which is aimed at increasing the loading capacity contributes to the increase of their draft and construction dimensions. This fact renders it necessary to develop ports and to interfere in the bathymetric layer of the basin, i.e. its deepening. However, the under keel clearance along the ship’s route and during the port towing maneuvers is often significantly limited. This makes it crucial to adapt the speed to the sailing conditions. Knowledge of the draft change with a low water level under the keel is important for the safety of navigation. Hence, the authors proposed expanding the maneuvering information contained in the ship's documentation with the additional curve of squat effect presented in the form of polynomial functions.

According to the definition in the resolution International Maritime Organization no A.860 (IMO 1997) navigation is the process of planning, recording, and controlling the movement of a craft from one place to another. When navigating in special conditions, for example, when approaching a port or in restricted areas, it is immensely important to know the vessel's maneuverability. Therefore, identifiable information must be available on each vessel. Each watch officer is required to have the necessary knowledge of both the equipment and maneuverability of his own vessel. The description and scope of the documentation containing this data are provided in IMO Resolution A.601 (IMO, 1987). The maneuver documents that must be available on the navigation bridge are Pilot Card and Wheelhouse Poster also Maneuvering Booklet. The timeliness of the data contained in the maneuver documentation significantly influences the safety of navigation. At present, the maneuver documentation is not created in an automated manner. Automation of registration and data processing process will increase the knowledge of the behavior of the own vessel. In addition, it allows to obtain maneuvering data that exceeds the parameters necessary to prepare ship documentation. Especially research carried out in various hydro-meteorological conditions, enabling the assessment of the movement of the ship on the waves. These data can be used to carry out research projects related to the subject of vessel behavior analysis. That is why the authors have made an attempt to automate the registration and processing of data necessary to create documents and their continuous generation in electronic form. In this article the authors present a proprietary computer application that enables the achievement of the assumed goals along with checking the application’s functionality on a selected type of a vessel. The correct operation of the system has been verified based on real study and simulation tests.
