Opis:
The main purpose of the paper is to recognize and characterize the substantial trends and ongoing phenomena as well as processes on the supply and demand side of the global ocean container market and then evaluate their impact on global supply chains and the whole mega logistics system. The author has analysed the dynamics of potential supply and effective demand growth on this market in the recent years and assessed changes observed on both market sides with respect to global logistics area. On this basis, the influence of global container market development on global logistics supply chains has been estimated. There were also presented and analysed the main effects of speeding-up implementation of disruptive innovations such as blockchain technology and digital trade platforms development in maritime container transport and trade sectors on the efficiency and effectiveness of global logistics chains and the whole logistics area. The issues related to the security of smooth digital development of container maritime transport and the mega logistics area were taken into consideration as well.

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:
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:
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 modern agglomerations development remains under the influence of current global trends: economic, environmental/climate, social, technological, geopolitical ones. At least six forces are expected to further disrupt the urban mobility landscape, especially coastal one. From self-driving vehicles and the sharing economy, to vehicle electrification, mobile computing, the Internet of Things and Block-chain technologies, each of these trends is quite significant on its own. The actions undertaken by city authorities aim at focusing citizens' attention on the need to improve air quality, decrease congestion in city’s main streets, invest in one’s health and physical condition, which increases the level of quality of life, and in turn provides the city with considerable economic benefits. The purpose of the paper is to explore global trends shaping life quality in coastal agglomerations with a special regard to sustainable mobility and to present the ISO 37120 - a tool allowing measurement, based on the indicators, of the cities resilience and performance.

Opis:
Nowadays shipping industry has problems such as reduction of mariners, aging of mariners, and labor expenses. To solve the problems, One Person Bridge Operation was developed as navigation supporting system. However, One Person Bridge Operation remained technological problems and one man error. Therefore, in this study, telexistence on a ship was proposed by using satellite communication. Telexistence on a ship is a concept of maneuvering between land and ship with at least two mariners such as navigation officer and helmsman. Navigation officer works on ship as usual and helmsman supports ship from land. In this paper, remote maneuvering system was developed as the first step of telexistence on a ship. For evaluating the effectiveness, ship experiment was carried out. From the result, navigation officer and helmsman could alter ship’s course to 20 degrees within 60 seconds and less than 5% overshoot in the proposed remote maneuvering system.

21st century challenges
Opis:
For nearly the entire post-World War II period, naval and air navigation relied primarily on ground-based radionavigation systems. However, the spontaneous development of satellite systems gradually led to their disappearance. They are currently used partly in air operations and marginally in maritime navigation in some areas around Asia, in Russia and in the Middle East. However, at the beginning of the 21st century, the threat of effective interference with satellite systems began to be raised, which led to an increased interest in restoring or upgrading ground-based systems as backup systems in the Western world. In this context, the approach of Russia is interesting, as it is associated with the vast majority of deliberate GPS interference. There are reports in the world literature that various ground-based radionavigation systems operating in Russia are still observed. The article analyses, on the basis of the few available sources, information on the ALFA system, about which the least is known, and there are many indications that it is ready for use.

Opis:
Bridge passing and passing waterway locks are two of the most challenging phases for inland vessel navigation. In order to be able to automate these critical phases very precise and reliable position, navigation and timing (PNT) information are required. Here, the application of code-based positioning using signals of Global Navigation Satellite Systems (GNSS) is not sufficient anymore and phase-based positioning needs to be applied. Due to the larger coverage area and the reduction of the amount of correction data Precise Point Positioning (PPP) has significant advantages compared to the established Real Time Kinematic (RTK) positioning. PPP is seen as the key enabler for highly automatic driving for both road and inland waterway transport. This paper gives an overview of the current status of the developments of the PPP algorithm, which should finally be applied in advanced driver assistant functions. For the final application State Space Representation (SSR) correction data from SAPOS (Satellitenpositionierungsdienst der deutschen Landesvermessung) will be used, which will be transmitted over VDES (VHF Data Exchange System), the next generation AIS.
