    Opis:
    A new localization approach to increase the navigational capabilities and object manipulation of autonomous mobile robots, based on an encoded infrared sheet of light beacon system, which provides position errors smaller than 0.02m is presented in this paper. To achieve this minimal position error, a resolution enhancement technique has been developed by utilising an inbuilt odometric/optical flow sensor information. This system respects strong low cost constraints by using an innovative assembly for the digitally encoded infrared transmitter. For better guidance of mobile robot vehicles, an online traffic signalling capability is also incorporated. Other added features are its less computational complexity and online localization capability all these without any estimation uncertainty. The constructional details, experimental results and computational methodologies of the system are also described.

    Opis:
    Dynamic technological progress is actively influencing the shape of modern education. Inventions that are constantly appearing on the market are often adapted to the needs of schools. One of the technologies that shows special potential in didactics is beacons. Beacons are small devices that can be used for communication, navigation and researching the recipient’s behavior. These functionalities are used in the education process, enabling the creation of completely new learning experiences. According to research, they can be successfully used in the classroom, during the formal learning process, as well as in various institutions, such as in informal transfer of knowledge, for example in cultural institutions. These sensors can contribute to the creation of a dynamic space for the exchange of knowledge and experiences, which will automatically respond to the individual needs of the recipient. The main goal of this article is to present the possibility of using beacons in the context of stationary education. The considerations were based on a review of the available literature. The work draws attention not only to the problems of the sensors themselves, but also to the possibility of their cooperation with other technologies. The collaboration of technical tools may contribute to the creation of more comprehensive solutions and, as a result, an increase in the quality and efficiency of the education process. However, as the analysis shows – beacons can be a promising technology in education, but their use is niche. Perhaps in future years, there will be more such solutions that will enable a more accurate assessment of these sensors. The author intends to continue her research to support the adoption of the described technology in Polish educational institutions.

    Opis:
    Thanks to the use of satellite positioning systems (including GPS) the ability to determine a user's position in open spaces has become a necessary element of everyday life. Nowadays people cannot imagine moving in an "urban jungle” with paper maps without electronic support, but dozens of years ago those maps were more popular than satellite navigation. A similar revolution may also await navigations in closed spaces such as public or commercial buildings. Because as the urbanisation process, the surfaces of various buildings grow, which significantly impedes orientation in them, especially for the blind or visually impaired users. As satellite navigation systems are burdened with errors, which increase when trying to use them in confined spaces, it becomes necessary to use more accurate technology. As a step towards solving this problem, we propose a solution supporting the navigation of users, especially the visually impaired, inside buildings. Our approach is based on using low energy Bluetooth transmitters and a method of determining the user's position using the trilateration algorithm and the appropriate placement of transmitters in a space.

    Opis:
    Signals from Global Navigation Satellite Systems are the primary source for Position, Navigation and Time (PNT) information onboard any vessel today. As these signals are prone to interference, a maritime backup system is needed to provide reliable PNT data, R(anging)-Mode is such a system. It utilizes existing maritime radio beacons or base stations of the Automatic Identification System (AIS) by adding ranging components to the legacy signals. The first modified radio beacons transmit medium frequency (MF) R-Mode signals in northern Germany. This paper has described the current state of the authors’ research and development activities at the receiver level for MF R-Mode signals. The receiver platform has been introduced, which was based on off-theshelf components and the implemented algorithms for distance estimation have been explained. Furthermore, the results of the first ranging measurements have been presented, which have shown the general suitability of the R-Mode technology as a source for maritime positioning and timing data.

    Opis:
    The use of SBAS corrections for navigation, in both coastal waters and inland waterways, has already brought the attention of many European authorities, which are interested in its potential to complement/replace their DGPS radio beacon networks. The European GNSS Agency (GSA) has an active long-term trajectory working to foster the EGNOS adoption in maritime through the launch of several actions whose results will pave the way for the provision of maritime EGNOS services. In this line, GSA awarded the consortium ALG-Indra, ESSP and Alberding with the Specific Contract GSA/OP/07/13/SC24 ‘Support to Maritime Service Providers for the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations’. The main objective of this Specific Contract is to demonstrate the operational performance of the transmission of EGNOS corrections converted to Differential GPS corrections over the existing transmission infrastructure (AIS base stations/IALA beacons) in the Maritime and Inland Waterways (IWW) domains, while providing a detailed cost benefit analysis of the solutions proposed. This service may complement the current GNSS augmentation services exploiting synergies and benefiting from the current infrastructure and standards, facilitating the adoption of EGNOS by maritime and inland waterways authorities. Furthermore, the service has no impact at user level since the DGNSS corrections are transmitted over the existing infrastructure, in the same format and implementing the same integrity mechanisms required for traditional IALA beacons ([1]). This project will allow the maritime and IWW service providers to have a clear understanding about the technical, operational and economic feasibility of the transmission of EGNOS corrections via IALA beacons and AIS/VDES stations.

    Opis:
    Kluczowym celem artykułu jest identyfikacja roli beaconów w komunikacji z niepełnosprawnym odbiorcą kultury. Na potrzeby podjętych badań przyjęto tezę, że beacony wspierają proces komunikacji rynkowej równych szans z niepełnosprawnym odbiorcą kultury. W celu weryfikacji przyjętej tezy zrealizowano wywiady pogłębione w wybranych instytucjach korzystających z beaconów. Uczestnicy przeprowadzonych wywiadów reprezentują środowisko instytucji kultury lub podejmują wybrane inicjatywy o charakterze kulturalnym. W badaniu uczestniczyli przedstawiciele następujących instytucji: Muzeum Pałacu Króla Jana III w Wilanowie, Urzędu Miasta i Gminy w Olkuszu (Szlak Gwarków), Muzeum Lotnictwa Polskiego w Krakowie, Muzeum Powstań Śląskich w Świętochłowicach oraz TAURON Arena w Krakowie. Wywiady zostały przeprowadzone w maju i czerwcu 2020 roku. W trakcie badań starano się także ustalić, w jakim stopniu wykorzystywane są funkcje beaconów w działaniach realizowanych na rzecz osób niepełnosprawnych przez podmioty uczestniczące w wywiadach. Stwierdzono, że instytucje stosujące beacony w procesie komunikacji rynkowej z niepełnosprawnymi odbiorcami kultury wykorzystują je najczęściej do wyrównywania szans przedstawicieli pojedynczych grup, z konkretnymi ograniczeniami fizycznymi.
    The presented study draws attention to the participation in the culture of people with disabilities. In the theoretical part, authors discuss the functionalities of beacons, which might be a useful tool in market communication of equal opportunities. The key goal of the article is to examine the role of beacons in market communication of equal opportunities with a disabled culture recipient. For the purposes of the undertaken research, a hypothesis was put forward that beacons support the process of market communication of equal opportunities with a disabled culture recipient. To verify the adopted hypothesis, authors carried in-depth interviews out in selected institutions using the discussed solution. Participants of the interviews represent the environment of cultural institutions or undertake selected cultural initiatives. In the presented study attended representatives of the following institutions: Museum of King Jan III's Palace in Wilanów, Town and Commune Office in Olkusz (Gwarków Trail), Polish Aviation Museum in Krakow, Silesian Uprising Museum in Świętochłowice and TAURON Arena in Krakow. During the research, it was also attempted to determine to what extent beacon functions are being used in marketing activities carried out for the benefit of disabled people by entities participating in interviews. Based on the research conducted, it was found that wider use of solutions based on the functionality of beacons can be achieved as a result of their adaptation to selected groups with particular dysfunctions.

    Opis:
    Purpose: The overriding goal of the presented considerations is to discuss beacons as consumer-brand touchpoints. In addition, the possibilities of using these sensors at various stages of the customer journey to implement the assumptions of the 5A model and build a lasting relationship with the buyer were indicated. Design/methodology/approach: In order to build a lasting relationship with the consumer, it is necessary to conduct multidimensional marketing communication based on numerous touchpoints. This interaction is assisted by mobile devices and many different technological solutions. One of them may be beacons, supporting consumer service at every stage of the customer journey. As part of the considerations, it was examined how the sensors can support marketing activities at individual stages of the customer journey. Findings: As part of the research, it was determined what role beacons can play at every stage of the customer journey, as well as their connections with promotion-mix elements. An attempt has been also made to indicate how these devices can create a holistic experience leading to buyer satisfaction and ultimately their loyalty. Research limitations/implications: The article contains a preliminary study. In the future it is planned to conduct additional quantitative and qualitative research. The study will help to perform a comprehensive analysis of the application being discussed. Practical implications: The article can help businesses to better realize the potential of beacons as a tool to support consumers during the shopping experience. It shows practical ways of using devices as part of individual promotional mix elements, which allows for their optimal use at all stages of the customer journey. Originality/value: Although the topic of beacons in commerce appears in academic publications, only a few of them relate these devices to the customer journey. This paper comprehensively deals with this topic and focuses on the relationship between sensors, the 5A model and the promotion mix tools.

    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 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.
