Opis:
According to the recommendation of the IMO Resolution MSC.252(83), “Adoption of the revised performance standards for integrated navigation system (INS)”, the INS is introduced in order to enhance navigational safety by providing integrated and augmented functions to avoid geographic, traffic and environmental hazards. Its main task is to provide ‘added value’ for the officer of the watch (OOW), ship’s captain and pilot, to plan, monitor or control the navigational safety and progress of the ship. The system should support navigational safety by combining, processing and evaluating inputs from different connected sensors and sources to provide information, giving timely warnings of dangerous situations, system failures and degradation of the integrity of delivered and presented information. An INS is defined as such if workstations provide multifunctional displays integrating at least the following navigational tasks (functions): route monitoring, collision avoidance and alert management. The output data contains a description of the subsystems and devices included in the INS, and the principles of their cooperation and presentation of data, but it does not present recommendations for interfacing the INS with the ship’s radio communications equipment or standardised rules of operation by the user and presentation of information. These restrictions limit the possibilities of using this system in e-navigation. This paper identifies the importance of these limitations with respect to the need for further development of INSs, and presents proposals to solve this problem.

Opis:
This paper presents operability guidelines for seafarers on a product tanker which navigates in the Adriatic Sea during heavy weather. Tanker route starts from the Otranto strait in the south to the island Krk in the north of Adriatic Sea. Heavy weather is caused by south wind called jugo (blowing from E-SE to SS-E, sirocco family). Operability guidelines are given based on an operability criteria platform for presenting ship seakeeping characteristics. Operability criteria considered in this paper are propeller emergence, deck wetness and bow acceleration of a product tanker. Limiting values of mentioned criteria determine sustainable speed. Heavy weather is described by extreme sea state of 7.5 m wave height. Wave spectrum used in this paper is Tabain spectrum which is developed specifically for Adriatic Sea. Seafarer’s approach of decisions making in extreme weather is also shown and servers as a guideline for further research of the authors.
W artykule przedstawiono propozycję wytycznych operacyjnych dla żeglugi tankowca na Morzu Adriatyckim podczas pogody sztormowej. Rozpatrywany szlak zaczyna się w cieśninie Otranto na południu i prowadzi do wyspy Krk na północy. Założono, że pogoda sztormowa jest spowodowana przez wiejący z kierunku SS-E wiatr południowy Jugo z grupy wiatrów lokalnych Sirocco. Zalecenia operacyjne zostały opracowane na podstawie kryteriów użytecznych dla osób odpowiadających za wachtę morską. Za takie uznano przede wszystkim: aspekt wynurzania się śruby napędowej, czynnik zalewania pokładu i przyspieszenia rejestrowane na dziobie statku. Wartości graniczne wspomnianych kryteriów określają dopuszczalną prędkość statku. Pogoda sztormowa została opisana przez dopuszczalny stan morza wyrażony wysokością fal (7.5 m). Dla opisu spektrum fal zastosowano kryterium Tabaina, najlepiej opisujące specyfikę Morza Adriatyckiego. Zaproponowane podejście zostanie również wykorzystane przez autora w dalszych badaniach.

Opis:
In this paper we present a new low-cost navigation system designed for small size Unmanned Aerial Vehicles (UAVs) based on Vision-Based Navigation (VBN) and other avionics sensors. The main objective of our research was to design a compact, light and relatively inexpensive system capable of providing the Required Navigation Performance (RNP) in all phases of flight of a small UAV, with a special focus on precision approach and landing, where Vision Based Navigation (VBN) techniques can be fully exploited in a multisensor integrated architecture. Various existing techniques for VBN were compared and the Appearance-Based Approach (ABA) was selected for implementation. Feature extraction and optical flow techniques were employed to estimate flight parameters such as roll angle, pitch angle, deviation from the runway and body rates. Additionally, we addressed the possible synergies between VBN, Global Navigation Satellite System (GNSS) and MEMS-IMU (Micro-Electromechanical System Inertial Measurement Unit) sensors, as well as the aiding from Aircraft Dynamics Models (ADMs). In particular, by employing these sensors/models, we aimed to compensate for the shortcomings of VBN and MEMS-IMU sensors in high-dynamics attitude determination tasks. An Extended Kalman Filter (EKF) was developed to fuse the information provided by the different sensors and to provide estimates of position, velocity and attitude of the UAV platform in real-time. Two different integrated navigation system architectures were implemented. The first used VBN at 20 Hz and GPS at 1 Hz to augment the MEMS-IMU running at 100 Hz. The second mode also included the ADM (computations performed at 100 Hz) to provide augmentation of the attitude channel. Simulation of these two modes was accomplished in a significant portion of the AEROSONDE UAV operational flight envelope and performing a variety of representative manoeuvres (i.e., straight climb, level turning, turning descent and climb, straight descent, etc.). Simulation of the first integrated navigation system architecture (VBN/IMU/GPS) showed that the integrated system can reach position, velocity and attitude accuracies compatible with CAT-II precision approach requirements. Simulation of the second system architecture (VBN/IMU/GPS/ADM) also showed promising results since the achieved attitude accuracy was higher using the ADM/VBS/IMU than using VBS/IMU only. However, due to rapid divergence of the ADM virtual sensor, there was a need for frequent re-initialisation of the ADM data module, which was strongly dependent on the UAV flight dynamics and the specific manoeuvring transitions performed.

Opis:
The paper presents a method of developing a variable structure measurement system with intelligent components for flight vehicles. In order to find a distinguishing feature of a variable structure, a numerical criterion for selecting measuring sensors is proposed by quantifying the observability of different states of the system. Based on the Peter K. Anokhin’s theory of functional systems, a mechanism of “action acceptor” is built with intelligent components, e.g. self-organization algorithms. In this mechanism, firstly, prediction models of system states are constructed using self-organization algorithms; secondly, the predicted and measured values are compared; thirdly, an optimal structure of the measurement system is finally determined based on the results of comparison. According to the results of simulation with practical data and experiments obtained during field tests, the novel developed measurement system has the properties of high-accuracy, reliable operation and fault tolerance.

The paper presents methods of on-line and off-line estimation of UAV position on the basis of measurements from its integrated navigation system. The navigation system installed on board UAV contains an INS and a GNSS receiver. The UAV position, as well as its velocity and orientation are estimated with the use of smoothing algorithms. For off-line estimation, a fixed-interval smoothing algorithm has been applied. On-line estimation has been accomplished with the use of a fixed-lag smoothing algorithm. The paper includes chosen results of simulations demonstrating improvements of accuracy of UAV position estimation with the use of smoothing algorithms in comparison with the use of a Kalman filter.

Opis:
The team of authors is engaged in the IMO corresponding group on INS / Alert Management and in national task groups primarily specialising in “Navigational Alert Management” matters. This presentation is based on the outcome of serious discussions carried out at different work group sessions in Germany and has been widely used as a guideline when details of an Alert Management concept are analysed (e.g. alert related communication and de-escalation strategies). A separate paragraph of definitions within this presentation describes “Function Alerts” which are not relevant for the navigational tasks carried out by the officer of the watch. Alerts appear to be nonrelevant became the subject under discussion whether their announcement should be automatically filtered out by a navigational module within an INS. This could be one effective method of resolution to minimise (the number of high priority) alerts.

Opis:
The current systems supporting navigation on board of ships are built on the classic concept for equipment: The system is developed, tested, type approved, installed and from that time on used with no or little modifications. Looking at other industries a regime of software and system maintenance has been established which allows more rapid updates. The development in the IT arena moves more towards modular approached, encapsulating individual components for easier implementation and delivery with limited system wide impact. This key concept is lately often referred to as the “app concept”. The e-Navigation development asks for exactly that: a way to improve innovation while ensuring system stability for the navigational components used by the navigator on the bridge. A key aspect of the success of new systems will be the ability to convert data into as information as needed in any given situation, creating knowledge for intelligent decisions increasing the competence of a navigator. The paper will focus on the following topics: – The classic “monolithic” Equipment paradigm – Modern System Architecture using components and “apps”-concept – Advantages of an approach using situational driven tool enhancements – The “app”-concept supporting the situational centric information presentation.

The maritime high speed craft navigators` ultimate aim has for decades been to safely and efficient navigate the vessel to its destination. The last decade an increased use of technology has arrived at the maritime ship bridge. The use of Electronic Charts and Integrated Navigation Systems has revolutionized much of the work of the navigator, with the aim of enhancing the safety of navigation. The amount of information has drastically increased, and the need for a proper information management and an efficient visual scan pattern has been identified. Looking to other industries this has been introduced with success, and in this paper the authors present a proposed scan pattern for the maritime navigator. The analysis is based on an eye tracking data set collected from simulator- and field studies on board the world’s fastest littoral combat ship.

Opis:
Digital selective calling (DSC) has a certain drawbacks, which have led to the fact that it is practically not used in address radio communications. Attempts to improve it only within the DSC system itself did not lead to any noticeable results due to neglecting of real user needs. The article proposes an approach to improve the user interface of DSC based on the integration of VHF MF/HF DSC equipment with the INS within the three main outputs of strategic direction of e-navigation development related to the integration of communication and navigation systems and, in particular, the S-mode. This approach allows us to significantly simplify the DSC user interface, based on the standardization of DSC integration for all three VHF MF/HF communication sub bands. For implementation such standardization an additional inclusion into the integration a satellite AIS system should be done. The feasibility of the proposal is supported by the existence of relevant IEC standards and IMO documents. The possibility of increasing the cyber security level of AIS messages in this interface is also considered.
