Opis:
This paper presents an analytical method for determining marine VHF communication bands based on the propagation model included in the International Telecommunication Union (ITU) recommendations. The developed method to determine communication bands was compared with the model recommended by the International Maritime Organization (IMO). The usefulness of the method developed by the authors has been demonstrated for the needs of the Radiocommunication Events Management System (REMS).

Opis:
Every type of training can be improved. Trying to find ways to do so is a continuous process. The identification and implementation of the most effective of those can only be adequate to the changing environment in case of objective review, comparison and analysis. This paper discusses some approaches whose adoption can lead to the enhancement of the training for radio operators for working in tactical net-works for the Navy. It also shares some experience from the implementation of such methods when training cadets at the Bulgarian Naval Academy.

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.

DGPS Correction Data Signal
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:
In Finland the Regional Fire and Rescue Services (RFRS) are responsible for near shore oil spill response and shoreline cleanup operations. In addition, they assist in other types of maritime incidents, such as search and rescue operations and fire-fighting on board. These statutory assignments require the RFRS to have capability to act both on land and at sea. As maritime incidents occur infrequently, little routine has been established. In order to improve their performance in maritime operations, the RFRS are participating in a new oil spill training programme to be launched by South-Eastern Finland University of Applied Sciences. This training programme aims to utilize new educational methods; e-learning and simulator based training. In addition to fully exploiting the existing navigational bridge simulator, radio communication simulator and crisis management simulator, an entirely new simulator is developed. This simulator is designed to model the oil recovery process; recovery method, rate and volume in various conditions with different oil types. New simulator enables creation of a comprehensive training programme covering training tasks from a distress call to the completion of an oil spill response operation. Structure of the training programme, as well as the training objectives, are based on the findings from competence and education surveys conducted in spring 2016. In these results, a need for vessel maneuvering and navigation exercises together with actual response measures training were emphasized. Also additional training for maritime radio communication, GMDSS-emergency protocols and collaboration with maritime authorities were seemed important. This paper describes new approach to the maritime operations training designed for rescue authorities, a way of learning by doing, without mobilising the vessels at sea.

Opis:
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.

Opis:
In this paper are introduced fundamentals, characteristics, advantages and disadvantages of Multiple Access (MA) employed as transmission techniques in the Maritime Mobile Satellite Communications (MMSC) between ships and Coast Earth Station (CES) via Geostationary Earth Orbit (GEO) or Not-GEO satellite constellations. In fixed satellite communication, as a rule, especially in MMSC many users are active at the same time. The problem of simultaneous communications between many single or multipoint mobile satellite users can be solved by using MA technique, such as Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Space Division Multiple Access (SDMA) and Random (Packet) Division Multiple Access (RDMA). Since the resources of the systems such as the transmitting power and the bandwidth are limited, it is advisable to use the channels with complete charge and to create a different MA to the channel. This generates a problem of summation and separation of signals in the transmission and reception parts, respectively. Deciding this problem consists in the development of orthogonal channels of transmission in order to divide signals from various users unambiguously on the reception part.
