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:: 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:: 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:: New shipping routes are emerging as a result of iceberg melting in polar regions, allowing for more efficient transport of people and goods. Opening of the Northwest Passage, the maritime route connecting Pacific Ocean with Atlantic Ocean through Arctic region, is considered such a development. The increasing transport exploitation of the Northwest Passage requires the quality assessment of maritime navigation aids for compliance with the established requirements. Here we contribute to the subject with addressing the polar commercial-grade GPS positioning performance in the Northwest Passage in the extreme positioning environment conditions during the massive 2003 space weather storm, a space weather event similar to the Carrington Storm of 1859, the largest space weather event recorded. The GPS positioning environment in the Northwest Passage during the Carrington-like storm in 2003 was reconstructed through the GNSS SDR receiver-post processing of the experimental GPS observations. The raw GPS dual-frequency pseudoranges and navigation messages were collected at the International GNSS Service (IGS) reference station at Ulukhaktok, Victoria Island, Canada. Pseudorange processing and GPS position estimation were performed in three scenarios of pre-mitigation of the ionospheric effects, known as the single major contributor GPS positioning error: (i) no corrections applied, (ii) Klobuchar-based corrected GPS positioning, and (iii) dual-frequency corrected GPS positioning. Resulting GPS positioning error vectors were derived as positioning error residuals from the known reference station position. Statistical properties of the northing, easting, and vertical components of the GPS positioning error vector were analyzed with a software developed in the R environment for statistical computing to select suitable methods for the GPS positioning error prediction model development. The analysis also identified the most suitable theoretical fit for experimental statistical distributions to assist the model development. Finally, two competitive GPS positioning error prediction models were developed, based on the exponential smoothing (reference) and the generalized regression neural networks (GRNN) (alternative) methods. Their properties were assessed to recommend their use as mitigation methods for adverse massive space weather effects in polar regions.

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:: 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:: Geodetic network GNSS receivers are more commonly associated with positioning systems used in maritime hydrography. In terms of positioning accuracy when no terrain obstacles are present, they meet international hydrographic surveys standards (S‐44) fully. Those standards are defined as 1m (0.95) for Exclusive Order and 2m (0.95) for Special Order. It is equally as important to ensure access to position which error is not higher than above mentioned maximum values. This is most often determined by the density of port infrastructure. This article presents the results of analysis of availability of hydrographic system that operates based on geodetic GNSS networks. Hydrographic surveys in question were undertaken in inner basins with diverse infrastructure. Three representative types of ports were selected for this reason: fishing type (Hel), medium sized, modern commercial type (Gdynia) and highly congested, narrow canal type (Gdansk – Motlawa). A nonpublic, geodetic GNSS network was used for all surveys. It is worth mentioning that the above network is at the moment the only available network that provides both GPS and GLONASS corrections. The surveys provided evidence that geodetic GNSS networks can be successfully utilised to determine position of hydrographic vessel in low and moderately developed ports as well as in Exclusive and Special Orders. In highly congested ports however, the availability of the above mentioned method of measurement can be insufficient to realise a survey.

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:: 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.

Here we present the results of a study of the effects of a fast-developing space weather disturbance on the positioning performance of a commercial-grade GPS+GLONASS receiver. Using experimentally collected pseudoranges and the RTKLIB, an open-source software-defined GNSS radio receiver operating in the simulation mode, we assessed GNSS positioning performance degradations for various modes of GNSS SDR receiver operation, and identified the benefits of utilisation of multi-GNSS and ionospheric error correction techniques.

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.

Opis:: Small autonomous surface vehicles (ASV) will need both teleoperation support and redundant positioning technology to comply with expected future regulations. When at sea, they are limited by a satellite communication link with low throughput. We have designed and implemented a graphical user interface (GUI) for teleoperation using a communication link with low throughput, and one positioning system, independent of the Global Positioning System (GPS), supported by the teleoperation tool. We conducted a user study (N=16), using real-world data from a field trial, to validate our approach, and to compare two variants of the graphical user interface (GUI). The users experienced that the tool gives a good overview, and despite the connection with the low throughput, they managed through the GUI to significantly improve the positioning accuracy.
