Opis:
The outbreak of the Covid 19 pandemic and the actions that all countries took in its aftermath all over the world in the first quarter of 2020 and later, i.e., during lockdowns and other restrictive measures, introducing a short and medium-term freezing of economic activity, had a strong impact on their economies and, consequently, also on the global economy. They hit seriously its particularly sensitive sectors, such as industry, trade and transport. The aim of undertaken research is to evaluate the impact of the pandemic on the functioning of maritime transport sector as well as to indicate its consequences for the global supply chains between 2020 and 2021 (first quarter). The research is mainly focused on assessing the impact of the Covid 19 pandemic on the global shipping and especially container one that is contemporarily the most vital link of the global intermodal land-sea supply chains. The analyses take into account the adaptive measures taken by ship operators and other individual parties being an integral link of the global supply chains with an aim to mitigate the effects of radical slowdown in industrial and global trade activity. The research was based on the analyses, reports and several business information carried out by specialized international organizations as well as ship carriers and logistics providers. The obtained research results indicate the need to reconfigure global logistics supply chains and increase their resilience by introducing new digital solutions. It is high time to introduce new smart, green digital supply chains and subsequently to reconfigure them much more towards the regional trade and economic relations and ties among countries (reshoring). Such activities aiming at rebuilding the logistic supply chains may at the same time change the presently existing business environment in global maritime shipping, enforcing not only changes in ship owners’ business models but also serious structural alterations on the shipping freight markets.

Opis:
International transport is a subject to many regulatory measures worked out by governments, international organisations (e.g. IMO, ILO, EU), regional institutions and public entities. As a result, such regulatory mechanism, which is getting throughout international, strongly affects the real sphere of maritime transport as well as its productivity and efficiency. Maritime transport operators have to apply to many new standards and rules set by international public regulators aimed mainly at improving and enhancing safety and security at sea. It is sometimes very painful process in terms of costs and time but inevitable to survive in the highly competitive environment. The author analyses the nowadays existing regulatory mechanism in maritime transport and tries to evaluate it in terms of its impact on effectiveness of maritime transport processes.

Opis:
Over the last decade the Global Positioning System has become a global, multifunctional tool which provides services that are an integral part of U.S. national security as well as the security of other highly developed countries. Economic development, transport security as well as homeland security are important elements of the global economic infrastructure. In 2000 the United States acknowledged the growing significance of GPS for civilian users and stopped intentionally degrading accuracy for non-military signals that are known as “Selective Availability”. Since then, commercial applications of satellite systems have been proliferating even more rapidly, and therefore, their importance in everyday life has greatly increased. Currently, services that depend on information obtained from the Global Positioning System are the driving force behind economic growth, economic development and the improvement in life safety. This economic development would not be possible without the financial and political support of the US government to maintain the operation of the GPS system. Therefore it is important to have knowledge about the intentions of the US government how system GPS will be developed in the future. Decisions taken in the last 3 months are the subject of this article.

Opis:
The rapid development of satellite navigation and timing technologies and the broad availability of user equipment and applications has dramatically changed the world over the last 20 years. It took 38 years from the launch of the world’s first artificial satellite, Sputnik 1, (October 4, 1957) to the day NAVSTAR GPS became fully operational (July 17, 1995). In the next 20 years user equipment became widely available at the consumer level, and 10 global and regional satellite systems were partially or fully deployed. These highly precise signals provided free to the user have been incorporated by clever engineers into virtually every technology. At the same time interference with these signals (spoofing and jamming) have become a significant day to day problem in many societies and pose a significant threat to critical infrastructure. This paper provides information on the current status and development of navigation satellite systems based on data provided by the systems' administrators. It also provides information on Loran/eLoran, a system which many nations have selected as a complement and backup for satellite navigation systems.

Opis:
The main subject of research involves the global freight market in the sector of container shipping, and in particular the mechanism for setting up freight rates. The aim of research is to identify and analyse the features and characteristics typical of this market, resulting from the character of market mechanism, as well as to indicate factors which determine market fluctuations and evaluate its impact for the carriers and shippers. Moreover, the causes and effects of fluctuations in effective demand and potential supply in the sector of freight market were identified in terms of their impact on freight rates. The analysis includes three main types of container markets, existing today on a global scale, and characterizes the strategies and modes of behaviour of global container operators undertaking activity on these markets. By applying the theory of mass random service and queueing theory to examine the container freight market mechanisms the method of freight rates short-term forecasting was presented which can be used as an instrument for taking decisions in the sector of global maritime logistics.

Opis:
Spatial segment is one of three segments of each satellite navigation systems (SNS). Nowadays two SNSs, GPS and GLONASS, are fully operational, two next SNSs, BeiDou in China and Galileo in Europe, are in final phase of the construction. In the case of China system this segment will consist of 35 satellites with three types of orbits ? medium (MEO), geostationary (GEO) and inclined geosynchronous (IGSO). As GEO and IGSO satellites can be used in China and Asia-Pacific region only, BeiDou MEO constellation with 27 fully operational satellites will be taken into account in this paper. The orbital planes of the Galileo constellation will be divided in “slots” that contains at least one operational satellite. The Galileo reference constellation has 24 nominal orbital positions or operational slots in MEO homogeneously distributed in 3 orbital planes; i.e. 8 slots equally spaced per plane. As the error of user’s position obtained from both systems depends on geometry factor DOP (Dilution Of Precision) among other things the knowledge of the number of satellites visible by the user above given masking elevation angle Hmin and the distributions of DOP coefficient values, GDOP in particular, is very important. The lowest and the greatest number of satellites visible in open area by the observer at different latitudes for different Hmin, the percentage of satellites visible above angle H, distributions (in per cent) of satellites azimuths and GDOP coefficient values for different Hmin for BeiDou and Galileo systems at different latitudes are presented in the paper.

Opis:
The main research issue refers to the identification and analysis of the key features and trends revealed on the global maritime container transport market in the years 2020-2022, as well as its general assessment in terms of the effects that such a highly concentrated market's supply side can cause for shippers and container shipping operators. The research is aimed at determining the main premises and factors stimulating the consolidation processes of the container shipping operators and ongoing market vertical and horizontal integration, as well as assessing the risks and effects resulting from maintaining the current system of regulation of this oligopolistic market. While conducting this research, the following methods were applied: factor analysis (FA), market analysis (MA) based on statistical data concerning the supply side, as well as desk research (DR), i.e. in-depth analysis of many reports, opinions, bulletins and data issued by international maritime organisations as well as research institutes. The obtained research results indicate that:1. the very advanced consolidation processes among the leading container shipping operators and, consequently, further integration of the container market, radically changes the balance of power in favour of shipping operators and creates the potential to generate serious disruptions in this market and other links in the global supply chains, 2/ regulatory antitrust authorities need to take appropriate regulatory action to limit their market power via legal measures regarding competition.

This paper discusses the current and new satellite transponders for global tracking and detecting of oceangoing ships, assets, crew, passengers and any moving objects at sea for enhanced vessels traffic control and management. These transponders are able to monitor all maritime assets and to improve safety, security of movements and collision avoidance, especially during very bad weather conditions and visibility. By deployment of the Global Navigation Satellite System (GNSS) in integration with Inmarsat, Iridium and other satellite systems in one unit with antenna, it is possible to provide reliable positioning and tracking solutions for civilian maritime, other mobiles and personnel at different Radio Frequency (RF) bands. The existing and forthcoming space and ground segment for positioning and tracking solutions as a modern Satellite Asset Tracking (SAT) onboard ships, and other relating systems are discussed and benefits of these new technologies and solution for improved positioning and tracking are explored.

Opis:
This paper presents a few general comments on the effective global ocean governance (GOG). The Convention on the Law of the Sea (UNCLOS) establishes fundamental legal principles for the governance of the marine environment and its resources. Furthermore, in the context of GOG the international community is conscious that improving of global and regional cooperation ought to be in the mainstream of socio-economic and political discourse. Nowadays, the UNCLOS is not able to give an answer for all new questions arising in the law of the sea. Therefore, it would seem that there is a great need to provide more pragmatic approaches to global ocean governance by international community as well as national governments, using the holistic paradigm of sustainable development. At the regional level, the European Union promotes an integrated maritime policy. Each EU marine Member State is obliged to prepare national integrated maritime policy as a part of the integrated maritime policy of EU. The Maritime Policy of Poland was approved by the Council of Ministers on 17 March 2015.

This article considers a new method of decomposing the ship route into global and local planning using MATLAB and Simulink developed by the authors. The authors propose to create a program code in MATLAB and operate it into Simulink. Wherein, the corrective coefficients were written in MATLAB. Such trajectories are constructed as a set of points, collected into the special matrix. In determining of the angle value of the rudder was used the ship’s turning ability such as: high (HG), middle (MD) or low (LW) with regard to passage area. Moreover, in the article were analyzed and calculated the ship rudder effectiveness for Proportional-Integral-Derivative (PID) control. The paper is devoted to the problem of safety navigation. First of all is the task of planning the path: the trajectory of the vessel’s movement in the local water area. The purpose of planning the vessel trajectory in the local water area is to ensure navigation safety due to marine traffic and environmental conditions. One of the tasks of the present work is controlling following a desired trajectory. The article notes affect of the vessel motion deviation into control process.

Opis:
Korean WA‐DGNSS is a large scale research project funded by Ministry of Land, Transport and Maritime Affairs Korea. It aims to augment the Global Navigation Satellite System by broadcasting additional signals from geostationary satellites and providing differential correction messages and integrity data for the GNSS satellites. The project is being carried out by a consortium of universities and research institutes. The research team at Electronics and Telecommunications Research Institute is involved in design and development of data processing softwares for wide area reference station and user segment. This paper focuses on user segment software design. Korean WA‐DGNSS user segment software is designed to perform several functions such as calculation of pseudorange, ionosphere and troposphere delays, application of fast and slow correction messages, and data verification. It is based on a layered architecture that provides a model to develop flexible and reusable software and is divided into several independent, interchangeable and reusable components to reduce complexity and maintenance cost. The current version is designed to collect and process GPS and WADGNSS data however it is flexible to accommodate future GNSS systems such as GLONASS and Galileo.

Opis:
A number of public codes exist for GPS positioning and baseline determination in off-line mode. However, no software code exists for DGPS exploiting correction factors at base stations, without relying on double difference information. In order to accomplish it, a methodology is introduced in MATLAB environment for DGPS using C/A pseudoranges on single frequency L1 only to make it feasible for low-cost GPS receivers. Our base station is at accurately surveyed reference point. Pseudoranges and geometric ranges are compared at base station to compute the correction factors. These correction factors are then handed over to rover for all valid satellites observed during an epoch. The rover takes it into account for its own true position determination for corresponding epoch. In order to validate the proposed algorithm, our rover is also placed at a pre-determined location. The proposed code is an appropriate and simple to use tool for post-processing of GPS raw data for accurate position determination of a rover e.g. Unmanned Aerial Vehicle during post-mission analysis.
