    Opis:
    This paper presents an overview of the development of a terrestrial positioning system called Ranging Mode (R-Mode) in the Southern Baltic Sea region which utilizes already existing maritime radio infrastructure. Here, an R-Mode testbed is planned to be set up until 2020 that meets maritime user needs for resilient PNT. First measurements of radio beacon signals on-board a vessel sailing in the Southern Baltic Sea show the good availability of beacon signals in this region. A comparison of received signals with a coverage prediction based on the nominal range of radio beacons shows the shortcoming of this approach and emphasizes the need for more elaborated coverage predictions which consider all effects of medium frequency wave propagation at day and night. In the measurements results the skywave has a major impact on the beacon signal stability in the night. The time stability of the signal amplitude seems to be a good indicator for disturbed reception conditions.

    Opis:
    User at the Inland Sea requires high position accuracy which is 5 m (2drms) or less. Therefore the position accuracy of standalone GPS is insufficiency. Consequently it needs to use DGPS for navigator sailing the Inland Sea. We executed numerical simulation of the propagation characteristic on the extended line of bridge pier at opposite side from DGPS station, and already confirmed that bit error in DGPS correction data signal occurs, and that correction data could not form by bit error. Furthermore, we carried out numerical simulation of the propagation characteristic of DGPS correction data signal received at sailing through center of the bridge, and solved receiving condition of DGPS correction data signal before and after passing through the bridge. In this paper, we executed to inspect mutually results of electric field intensity simulation for oversea and overland propagation on some sea area of the Inland Sea and measuring results of electric field intensity for DGPS correction data signal, and evaluated the possibility of abnormal propagation comprehensively.

    Opis:
    At the turn of the 20th and 21st centuries, Global Navigation Satellite Systems (GNSSs) dominated navigation in air, sea, and land. Then, medium-range and long-range terrestrial navigation systems (TNSs) ceased to be developed. However, with the development of GNSS jamming and spoofing techniques, the TNSs are being re-developed, such as the Enhanced Loran. The Polish Ministry of Defense plans to develop and implement a medium-range backup navigation system for the Polish Navy which will operate in the Baltic coastal zone. This plan is a part of the global trend. This paper presents the concept of a reserve TNS (RNS) that is based on the signal Doppler frequency (SDF) location method. In 2016, the concept of the RNS, which is based on stationary radio beacons located on coastal lighthouses, has been presented. From the military viewpoint, the use of the mobile radio beacons, which may change their location, is more justified. Therefore, the paper presents an idea of using the mobile beacons for this purpose. In this paper, effectiveness of the mobile RNS is shown based on simulation studies.

    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:
    This research features an overview of the available PLB technologies, their advantages, shortcomings and areas of their optimum application. A test of the locator transmitter emitting both 406 MHz AIS and 121.5 MHz signals was performed with a focus on tracking the homing 121.5 MHz signal. The efficiency of the homing signal was examined by using two separate radio locating systems. One of them comprised multi-purpose and widely available components and programs, while the other was a specialised radio beacon system with dedicated components. In addition to the results, their analysis and evaluation of efficiency, the paper discusses the applicability of the available PLB technologies and provides guidelines for adequate selection of the PLB devices and position indicating radio equipment.

    Opis:
    A Yagi plasma antenna model was established by HFSS according to the relationship between plasma dielectric constant and electron density. The patterns were simulated by changing plasma parameters and the number of director dipoles. Results show that when the passive vibrators were switched off, the antenna is omnidirectional antenna. The directionality increases with the increase of the number of passive dipole and the main lobe of which narrows down. Then the plasma Yagi antenna model is established by plasma tube, the gain changed by changing the number of passive dipoles, so the plasma Yagi antenna has a very good reconfigurability. Results prove that the feasibility of the plasma Yagi antenna can be used on AIS base station of Ships’ Routeing waters. It can promote the communication and capability of maritime supervision in Ships’ Routeing waters.

    Opis:
    Today, a significant number of quite advanced technology applications support safety at sea. To the dismay of the maritime industry, the manifestation of passengers during an evacuation scenario/case has not followed a similar path of improvement, when compared to the counterpart Life Saving Appliances (LSA) Code. Embarkation and muster proceedings are still following the similar approaches that were established during the early 1900s. There have been relatively few advances in these procedures; most often, they include manually checking-in the passengers on electronic systems, along with “on the spot” completion of check-off lists and passenger counts, allowing for an influx of potential error by the concerned personnel. Furthermore, the rely and transmission of the manifest to a Maritime Rescue Coordination Centre (MRCC) is often associated with a considerable amount of time, or even involving secondary passenger counts, after the disembarkation event has been concluded. It is understandable that a vessel with limited people on-board (tankers, bulk carriers, container vessels, etc.) can effectively be abandoned in a matter of minutes, but what happens with vessels carrying a large number of passengers and more specifically those heavily engaged with cruising activities? This paper examines the creation of an electronic manifestation system that will be able to automatically record the passengers during lifeboat embarkation. This proposed system will employ the use of Near-Field Communication (NFC) and/or (Radio-frequency identification) RFID bracelets, that are already utilized within the cruise industry. It will record relevant passenger and crew data, upon their boarding on the designated lifeboat, through readers installed on the parallel sides of the entryway. The data will be displayed in electronic tablet devices to the lifeboat leaders, as well as to the Master of the vessel in real-time. This will allow for an accurate representation of the evacuation process in any given moment. Furthermore, a complete “snapshot” of that information can also be directly transmitted to the MRCC via an automated message and without any further human intervention, or even stored locally aboard the lifeboats used for the evacuation and the ship’s Vessel Data Recorder (VDR).

    Opis:
    Satellite navigation gains importance in sustainable development of modern civilisation. With the increasing number of GNSS-based technology and socio-economic systems and services, satellite navigation has become an essential component of national infrastructure. This calls for novel requirements on GNSS positioning perfomance, and increasing need for resilient GNSS development. Here we examined the impact of rapidly developing tropical cyclone on GPS positioning performance degradation, and the resulting impact on oceanic non-navigation and navigation GPS applications. We presented the methodology for indirect simulation-based GPS positioning performance evaluation through utilisation of experimental GPS observations, GNSS Software-Defined Radio (SDR) receiver, and a statistical analysis and framework we developed in the R environment for scientific computing. We identified alteration of GPS positioning error components time series statistical properties, and discuss the potential impact on GPS-based services essential for remote oceanic island communities. Manuscript concludes with the summary of findings, proposal for recommendations on improved GNSS resilience, and an outline for future research.

    GNSS positioning performance assessment is essential for sustainable development of a growing number of GNSS-based technology and socio-economic applications. Case-studies of GNSS positioning performance in critical environments and applications scenarios reveals vulnerabilities of the GNSS Positioning, Navigation, and Timing (PNT) services, and suggest mitigation techniques and GNSS application risk containment. Here we address the case of GPS positioning performance during a devastating tropical cyclone Marcus that hit the greater area of the city of Darwin, Australia in 2018. We identified specific statistical properties of time series of tropospheric contribution to GPS northing, easting, and vertical positioning error that may contribute to understanding of tropospheric effects on GPS positioning performance during a massive weather deterioration in maritime and coastal areas, and analysed their adversarial effects on GNSS-based maritime applications.

    Audio watermarking (AW) technology is considered for stealthy information embedding directly into audio signal. Inherent in analog radiotelephone channel interferences against watermarks are analyzed. Robust encoding/decoding algorithms are presented and appropriate project of AW system named as Automatic Radio Telephone Identification System (ARTIS) is proposed. Experimental results for the practical VHF radio channel are presented. Relating on processing complexity the designed system enables imperceptibly transmit data on a rate up to 260 bit/sec in the standard VHF radio channel. ARTIS provides the full compatibility with the existing radio installation, and doesn’t require replacement of standard VHF transceivers and operational procedures. Besides, automatic identification the system may be used in the special applications, for example, under the threat of terrorist attack; generally contributes to navigation safety and information security.
