: In this contribution we present a review of the DIA ‐ method to ensure navigational integrity. The DIA ‐ method rigorously combines parameter estimation and statistical testing for the Detection, Identification and Adaptation of multivariate and multiple model misspecifications. We describe the statistical properties of the so ‐ obtained DIA ‐ estimator together with its probability density function. Numerical examples are given to highlight various aspects of the navigational DIA ‐ estimator.

: Due to the ongoing climate change, the European Commission is implementing the promotion of inland waterway transport. By creating favourable conditions for the further development of the sector, the Commission hopes to encourage more companies to use this mode of transport. The policy to promote inland waterway transport in Europe is encapsulate d in the NAIADES Action Programme. Carriage of goods by inland waterways is climate -friendly and energy-efficient and can significantly contribute to sustainable mobility in Europe. The European Commission believes that transport by inland waterways must b e better used in order to relieve heavily congested transport corridors.

: Sustainable mobility is one of the key elements determining the correct operationalization of the idea of sustainable development. This concept also appears more and more often in modern cities, whose authorities strive to improve the quality of life of their inhabitants, among others by creating SUMP -Sustainable Urban Mobility Plan. This is followed by all kinds of facilities that generate big traffic in cities. One of the institutions willing to meet the challenges of the ever - growing number of tr ips in its vicinity is Gdynia Maritime University (GMU), which is one of the largest employers in this seaport city, and thus – is one of the biggest traffic generators. The objective of this paper is to investigate the prerequisites and perspectives of creating and implementing mobility plan for GMU in order to make transport more sustainable in its vicinity. For this purpose, pilot research survey has been carried out among employees and students regarding their behaviour and transport preferences in reaching this destination. The research hypothesis stating that the transport habits of the GMU commuters are not compatible with the concept of sustainable mobility was confirmed. The implementation of a sustainable mobility plan in this institution will help to change the standards of traveling in the area of the University and will contribute to better quality of life in the city. It is recommended to enhance the cooperation with the Gdynia City Hall in order to create a synergy effect and bring an added val ue to sustainable development of this congested seaport urban space.

: The main goal of education at a maritime university is to provide students with knowledge and practical skills necessary for future work on a ship. To receive the diploma of merchant navy officer, students are required to complete a 12 ‐ month maritime internship. During the internship, as well as during the entire course of studies, students ʹ expectations regarding their future professional work are developed, related to, among others, working and living conditions on a ship, employment conditions and cooperation with the shipowner. These expectations determine the students’ subsequent choices towards a given shipowner as a potential employer, as well as their decisions about further professional development in this field. From the point of view of operational management, it is therefore important for the shipowner to know the requirements that must be met in order to have a motivated and competent staff. This article aims to classify the requirements for students relative to their future work on a ship based on assessing the impact of the requirement fulfilment level against the level of their satisfaction. The results obtained made it possible to indicate those requirements regarding working conditions, the fulfilment of which should be treated by shipowners as a priority, because they determine the students’ satisfaction to the highest degree.

: The GNSS positioning performance is commonly defined and described in terms unspecified to particular GNSS-based application. The approach causes difficulties to GNSS application developers, operators, and users, rendering the impact assessment of GNSS performance on the GNSS application Quality of Service (QoS) particularly difficult. Here the Probability of Occurrence (PoO) Model is introdu ced, which allows for a risk assessment of the probability for the GNSS positioning accuracy failure to meet the requirements of the particular GNSS-based application. The proposed PoO Model development procedure requires a large set of position estimation errors observations, which shall cover a range of classes of positioning environment (space weather, troposphere, multi -path etc.) disturbances affecting GNSS positioning accuracy. As result, the PoO Model becomes a tool that returns the probability of failure in meeting the positioning accuracy requirements of the GNSS applications considered, thus providing the input for a GNSS deployment risk assessment. The proposed PoO Model and its development procedure are demonstrated in the case of polar region positioning environment, with raw GNSS pseudorange observations taken at the International GNSS Service (IGS) Network reference station Iqualuit, Canada are used for the PoO Model development. The PoO Model proof-of-principle is then used to estimate the probability of the unmet required positioning accuracy for a number of polar maritime navigation applications. Manuscript concludes with a discussion of the PoO Model benefits and shortcomings, a summary of contribution, and intentions for the future research.
:全球导航卫星系统定位性能的定义和描述通常不针对特定的基于全球导航卫星系统的应用。这种方法给GNSS应用开发者、运营商和用户带来了困难，使GNSS性能对GNSS应用服务质量(QoS)的影响评估变得尤为困难。这里引入了发生概率模型(Probability of Occurrence Model, PoO)，该模型允许对GNSS定位精度无法满足特定GNSS应用要求的概率进行风险评估。所提出的PoO模型开发过程需要大量的位置估计误差观测数据，这些观测数据应涵盖影响GNSS定位精度的一系列定位环境(空间天气、对流层、多径等)干扰。因此，PoO模型成为一种工具，可以返回所考虑的GNSS应用无法满足定位精度要求的概率，从而为GNSS部署风险评估提供输入。在极地定位环境下，利用国际GNSS服务(IGS)网络参考站Iqualuit，加拿大的原始GNSS伪距观测数据，演示了所提出的PoO模型及其开发过程。然后使用PoO模型原理验证来估计未满足极地海上导航应用所需定位精度的概率。论文最后讨论了便便模型的优点和缺点，总结了贡献，并对未来的研究意图。

: Simulator-based training has become an integral part of Maritime education, and its effectiveness hinges on the use of appropriate assessment protocols. Despite the existence of several subjective and objective assessment techniques, instructors face difficulties in selecting and implementing the best practices that fit different learning contexts. The contextualized utility of the available assessment techniques further complicates the contexts. T his study adopts a systematic literature review approach to comprehensively analyse available assessment techniques employed in maritime simulator training and to elicit their relationship with the desired learning outcomes. The study also presents a nuanced understanding of the advantages and limitations of the identified assessment techniques. Further, the state-of-the-art of assessment methods is discussed along wi th a few proposal s for the future considering both research and practical implications. The findings of this study are expected to provide valuable guidance to maritime instructors in selecting and implementing appropriate assessment techniques that align with desired learning outcomes in simulator training.

: The article presents an approach to formulating a ship control process model in order to solve the problem of determining a safe ship trajectory in collision situations. Fuzzy process properties are included in the model to bring it closer to reality, as in many situations the navigator makes a subjective decision. A special neural network was used to solve the presented problem. This artificial neural network is characterized by minimum and maximum operations when set. In order to confirm the correctness of the operation of the proposed algorithm, the results of the simulations obtained were presented and an discussion was conducted.
