Opis:
Soldiers are the backbone of any armed force. They usually lose their lives due to the lack of medical assistance in emergency situations. Furthermore, army bases face problems due to the inability to track soldiers’ locations in the field. Hence, this paper proposes an interactive graphical user interface module (IGUIM) for soldiers’ bioinformatics acquisition and emergency reaction during combat, a global positioning system (GPS) is used to track soldiers’ locations through a device carried by the soldier. Soldiers’ bioinformatics are gathered using health monitoring biosensors, bidirectional communication between the soldiers and the army base is established via a global system for mobile (GSM). The proposed interactive module aims to enumerate the soldiers on the battlefield within a database that easily facilitates health monitoring, position tracking and bidirectional communication with each soldier through their identification number. The proposed IGUIM will increase the rate of soldiers’ survival in emergencies, which contributes to preserving the human resources of the army during combat.

Opis:
Citizen diplomacy as a key component of diplomacy is fundamental in international relations. Through it, individual citizens help realize their countries’ national interests through unofficial interactions. For Nigeria however, the worry is whether citizen diplomacy can effectively complement official diplomatic activities in the face of the low human-capital development of her citizens. United Nations Development Pro-gramme in 2019 placed Nigeria’s human-development-index value for 2018 at 0.534, positioning the country at 158 out of the 189 countries and territories surveyed. It also classified 51.4 percent of Nigerian population as being multi-dimensionally poor with an additional 16.8 percent categorized as being vulnerable to multidimensional poverty. In view of this challenge therefore, this paper examined the implication of the low human-capital development on foreign relations of Nigeria. Data was collated from secondary sources while qualitative descriptive technique was used for analysis. The paper found that Nigeria’s current human capital development trajectory is incapable of stimulating citizen diplomacy into complementing the country’s official diplomatic relations with other states. It also found that this situation accounts for the failure by Nigeria to actualize most of her foreign policy objectives. The paper therefore recommended improved investment in wellbeing of Nigerians for better outing in foreign relations.
Dyplomacja obywatelska jako kluczowy komponent dyplomacji ma znaczenie fundamentalna w stosunkach międzynarodowych. Dzięki niej poszczególni obywatele pomagają realizować interesy narodowe swoich krajów po-przez nieoficjalne interakcje. W przypadku Nigerii niepokoi jednak kwestia efektywności uzupełniania przez dyplomację obywatelską czynności dyplomatycznych ze względu na niski poziom rozwoju kapitału ludzkiego jej obywateli. Program Narodów Zjednoczonych ds. Rozwoju w roku 2019 uplasował wartość wskaźnika rozwoju społecznego Nigerii na rok 2018 na poziomie 0,534, czyli na 158 miejscu z 189 badanych krajów i terytoriów. Sklasyfikował również 51,4 procent populacji Nigerii jako biednych wielowymiarowo, a dodatkowe 16,8 procent sklasyfikowano jako narażone na wielowymiarowe ubóstwo. W związku z tym w niniejszym dokumencie przeanalizowano wpływ niskiego rozwoju kapitału ludzkiego na stosunki Nigerii z zagranicą. Dane zostały zebrane ze źródeł wtórnych, natomiast w analizie została zastosowana jakościowa technika opisowa. W artykule wskazuje się, że w Nigerii aktualnie trajektorie rozwoju kapitału ludzkiego nie są w stanie stymulować dyplomację obywatelską w zakresie uzupełniania oficjalnych relacji dyplomatycznych z innymi krajami. Zostało odnotowano, że ta sytuacja także jest przyczyną niepowodzenia Nigerii w kontekście aktualizacji celów polityki międzynarodowej Nigerii. W tym artykule zawarte są zalecenia poprawienia inwestycji w dobrostan Nigeryjczyków dla lepszych wyników w relacjach z zagranicą.

Opis:
Korean WA‐DGNSS is a large scale research project funded by Ministry of Land, Transport and Maritime Affairs Korea. It aims to augment the Global Navigation Satellite System by broadcasting additional signals from geostationary satellites and providing differential correction messages and integrity data for the GNSS satellites. The project is being carried out by a consortium of universities and research institutes. The research team at Electronics and Telecommunications Research Institute is involved in design and development of data processing softwares for wide area reference station and user segment. This paper focuses on user segment software design. Korean WA‐DGNSS user segment software is designed to perform several functions such as calculation of pseudorange, ionosphere and troposphere delays, application of fast and slow correction messages, and data verification. It is based on a layered architecture that provides a model to develop flexible and reusable software and is divided into several independent, interchangeable and reusable components to reduce complexity and maintenance cost. The current version is designed to collect and process GPS and WADGNSS data however it is flexible to accommodate future GNSS systems such as GLONASS and Galileo.

Opis:
The idea of C/A codes GPS/GNSS Spoofing (Substitution), or the ability to mislead a satellite navigation receiver into establishing a position or time fix which is incorrect, has been gaining attention as spoofing has become more sophisticated. Various techniques have been proposed to detect if a receiver is being spoofed – with varying degrees of success and computational complexity. If the jammer signals are sufficiently plausible then the GNSS receiver may not realize it has been duped. There are various means of detecting spoofing activity and hence providing effective mitigation methods. In this paper, a novel signal processing method applicable to a single antenna handset receiver for spoofing detection has been described. Mathematical models and algorithms have been developed to solve the problems of satellite navigation safety. What has been considered in the paper is a spoofing detection algorithm based on the analysis of a civil satellite signal generated by mobile C/A GPS/GNSS single-antenna receivers. The work has also served to refine the civilian spoofing threat assessment by demonstrating the challenges involved in mounting a spoofing attack.

Opis:
The possibilities to improve values of the satellite orbit elements by employing the pseudo-ranges and differences of carrier phase frequencies measured at many reference GPS stations are analysed. An improvement of orbit ephemeris is achieved by solving an equation system of corrections of the pseudo-ranges and phase differences with the least-squares method. Also, equations of space coordinates of satellite orbit points expressed by ephemeris at fixed moments are used. The relation between the accuracy of the pseudo-ranges and phase differences and the accuracy of the satellite ephemeris is analysed. Formulae for estimation of the influence of the ephemeris on the measured pseudo-ranges and phase differences and for prediction of the accuracy of the pseudo-ranges and phase differences were obtained. An influence of the covariance between single orbit parameters on the accuracy of the pseudo-ranges and phase differences is detected.

Opis:
Differentiation of actors derives primarily from the distribution of power and wealth in a society, and thus it has always played an exceptionally significant role. However, as a consequence of the hierarchical organisation of the society this differentiation was noticeably asymmetrical. The non-equivalence of partial subjects/actors of regional development has led to the understandable domination of ‘deterministic’ relations and the plurality of interests and then to the dominance of ‘competitive’ relations. Only gradually do interactions of a cooperative kind successively break through the growth of mutual interconnections, linkages and necessity of social elements and partial systems, and thus the increasing of organic nature of (geo)societal systems. This will be finally illustrated through the difference between ‘symmetric’ systems of actors in developed countries and the ‘asymmetric’ global system.

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:
The article reveals the contradiction between the role of the US dollar as the main global re-serve currency and its national origin, which causes the misuse by the US government to cover the chronic trade and budget deficit. The author researches the crisis management transformation tendencies of the global mone-tary system, namely the weakening positions of the US dollar and euro as the key reserve curren-cies; the gradual formation of the regional monetary unions; the shifting to the national currencies in mutual trade and settlement operations without the US dollar mediation; the gradual replace-ment of the US dollar by the Chinese Yuan as the key reserve currency. The author discloses that the future key regional currencies are “amero” in the USA, Canada and Mexico; “afro” in Africa; “pachu” in Latin America; ACU in the Asian and Pacific region; “Golden dinar” in the Persian Gulf region; “sucre” in the Caribbean region; “euras” in the Europe-an and Asian Economic Commonwealth.
Artykuł ukazuje sprzeczności pomiędzy rolą dolara amerykańskiego jako głównej globalnej waluty rezerwowej a jego narodowym charakterem, co powoduje niewłaściwe jego wykorzystanie przez rząd Stanów Zjednoczonych do pokrywania chronicznego handlowego i budżetowego deficytu. Autor badaniom poddaje tendencje transformacyjne w ramach zarządzania kryzysowego globalnym systemem pieniężnym, w szczególności osłabianie się pozycji dolara i euro jako kluczowych walut re-zerwowych, stopniowe kształtowanie się regionalnych unii walutowych, zwrot w kierunku walut naro-dowych we wzajemnym handlu i operacjach inwestycyjnych bez pośrednictwa dolara, stopniowe zastę-powanie dolara amerykańskiego przez chińskiego yuana jako kluczowej waluty rezerwowej. Autor przewiduje, że kluczowymi regionalnymi walutami w przyszłości będą „amero” w Stanach Zjednoczonych, Kanadzie i Meksyku; „afro” w Afryce; „pachu” w Ameryce Łacińskiej; ACU w regionie Azji i Pacyfiku; „złoty dinar” w regionie Zatoki Perskiej; „Sucre” w regionie Karaibów: „euras” we Wspólnocie Gospodarczej Europy i Azji.

Electromagnetic radiation exposure increases with the rise of the wireless communication devices. Electromagnetic radiation, especially near 2400 MHz band, has gradually increased with the widespread of wireless fidelity adapter in indoor environment. In this study, electromagnetic radiation in dwellings where different Wi-Fi adapters and routers are used was assessed by measuring the electric field and compared with other electromagnetic radiation source and the limits set by the Information and Communication Technologies Authority. Measurements were taken in the range of 760-2690 MHz bands used by GSM, 3G/LTE and Wi-Fi technologies. The detected values for all frequencies are significantly lower than the limits of the Information and Communication Technologies Authority. Among the electromagnetic radiation sources, electromagnetic radiation of Wi-Fi adapter is higher than GSM/3G/LTE sources radiation in dwellings. Electromagnetic radiation values in nearest point of high power adapter Wi-Fi antenna are close to the Information and Communication Technologies Authority limit value. Results show that electromagnetic radiation based on Wi-Fi adapters or routers can be higher than GSM based electromagnetic radiation.

Opis:
Ochrona środowiska jest dziedziną wiedzy odnoszącą się w sposób ścisły do przestrzeni geograficznej – przestrzeni, która przy tym poziomie antropopresji wymaga metod pozwalających na szybkie podejmowanie prawidłowych decyzji. Doskonałym narzędziem wspomagającym proces decyzyjny są systemy informacji przestrzennej, będące tą gałęzią wiedzy, której rozwój w sposób ścisły zależy od źródeł danych i metod ich pozyskiwania. Jedną z najlepszych technologii mogących zaspokoić te potrzeby są systemy nawigacji satelitarnej. Ta stosunkowo prosta i szybka metoda realizacji pomiarów bezpośrednio w terenie znalazła wielu zwolenników szczególnie wśród osób poszukujących rozwiązań mogących zastąpić kosztowne i czasochłonne klasyczne pomiary geodezyjne. Dokonując wyboru pozornie prostej technologii, jaką są systemy nawigacji satelitarnej należy mieć świadomość zarówno jej ograniczeń, ale także nie w pełni wykorzystywanego potencjału.
Knowledge about environmental protection refers strictly to geography information. High level of anthropogenic impact needs efficient methods in order to make good decisions. Geographical information system (GIS) is a prefect tool which helps in this situation. On the other hand GIS must be supplied by fast and accurate geographical information. The best solution to this is global navigation satellite systems technology. It is useful especially for users who want to replace cost and time consuming geodetic surveying. Using global navigation technology is simple but it has some limitations as well. It is also observed that many users can not use navigation receiver correctly and they loose a chance for accurate data.

Opis:
Geodetic network GNSS receivers are more commonly associated with positioning systems used in maritime hydrography. In terms of positioning accuracy when no terrain obstacles are present, they meet international hydrographic surveys standards (S‐44) fully. Those standards are defined as 1m (0.95) for Exclusive Order and 2m (0.95) for Special Order. It is equally as important to ensure access to position which error is not higher than above mentioned maximum values. This is most often determined by the density of port infrastructure. This article presents the results of analysis of availability of hydrographic system that operates based on geodetic GNSS networks. Hydrographic surveys in question were undertaken in inner basins with diverse infrastructure. Three representative types of ports were selected for this reason: fishing type (Hel), medium sized, modern commercial type (Gdynia) and highly congested, narrow canal type (Gdansk – Motlawa). A nonpublic, geodetic GNSS network was used for all surveys. It is worth mentioning that the above network is at the moment the only available network that provides both GPS and GLONASS corrections. The surveys provided evidence that geodetic GNSS networks can be successfully utilised to determine position of hydrographic vessel in low and moderately developed ports as well as in Exclusive and Special Orders. In highly congested ports however, the availability of the above mentioned method of measurement can be insufficient to realise a survey.

Opis:
Under the umbrella of PWSZ Chelm, taking account of future implementation of navigation using EUPOS and GNSS based on EGNOS several planned actions were carried out in the 2005-2006. The actions in particular contribute to: 1. ICAO and EGNOS requirements and coverage area (Chelm Town located near Polish-Ukrainian border is also at the east border of planned EGNOS coverage for ECAC states). 2. Preparatory activities to establishing the EUPOS station in PWSZ Chelm. Cooperation of PWSZ Chelm and ULC (Polish Aviation Regulator) in the frame of conventional NAV aids use and GNSS implementation in aviation. 3. Analysis of ICAO requirements and methods of testing SIS (Signal In Space) needed to certify GNSS in Poland for use for an aviation. 4. Preparatory activities to establishing the EGNOS SIS monitoring station based on EUROCONTROL Pegasus software and GNSS/EGNOS receiver Septentrio PolaRx2e. 5. Analysis of methods for exchange of information between EUPOS and EGNOS SIS station to initiate the application of satellite positioning systems to air navigation in Poland. The project EUPOS is a European initiative aiming at establishment of a uniform DGNSS (Differential Global Navigation Satellite System) basis infrastructures in Central and Eastern European countries including Chelm Town where PWSZ is localized playing vital role in GIS/GNSS implementation in the region and Polish aviation.

Opis:
The rapid development of satellite navigation and timing technologies and the broad availability of user equipment and applications has dramatically changed the world over the last 20 years. It took 38 years from the launch of the world’s first artificial satellite, Sputnik 1, (October 4, 1957) to the day NAVSTAR GPS became fully operational (July 17, 1995). In the next 20 years user equipment became widely available at the consumer level, and 10 global and regional satellite systems were partially or fully deployed. These highly precise signals provided free to the user have been incorporated by clever engineers into virtually every technology. At the same time interference with these signals (spoofing and jamming) have become a significant day to day problem in many societies and pose a significant threat to critical infrastructure. This paper provides information on the current status and development of navigation satellite systems based on data provided by the systems' administrators. It also provides information on Loran/eLoran, a system which many nations have selected as a complement and backup for satellite navigation systems.

Opis:
Spatial segment is one of three segments of each satellite navigation systems (SNS). Nowadays two SNSs, GPS and GLONASS, are fully operational, two next SNSs, BeiDou in China and Galileo in Europe, are in final phase of the construction. In the case of China system this segment will consist of 35 satellites with three types of orbits ? medium (MEO), geostationary (GEO) and inclined geosynchronous (IGSO). As GEO and IGSO satellites can be used in China and Asia-Pacific region only, BeiDou MEO constellation with 27 fully operational satellites will be taken into account in this paper. The orbital planes of the Galileo constellation will be divided in “slots” that contains at least one operational satellite. The Galileo reference constellation has 24 nominal orbital positions or operational slots in MEO homogeneously distributed in 3 orbital planes; i.e. 8 slots equally spaced per plane. As the error of user’s position obtained from both systems depends on geometry factor DOP (Dilution Of Precision) among other things the knowledge of the number of satellites visible by the user above given masking elevation angle Hmin and the distributions of DOP coefficient values, GDOP in particular, is very important. The lowest and the greatest number of satellites visible in open area by the observer at different latitudes for different Hmin, the percentage of satellites visible above angle H, distributions (in per cent) of satellites azimuths and GDOP coefficient values for different Hmin for BeiDou and Galileo systems at different latitudes are presented in the paper.

Opis:
The understanding of the ionospheric effects on GNSS positioning performance forms an essential pre-requisite for resilient GNSS development. Here we present the results of a study of the effects of a fast-developing space weather disturbance on the positioning performance of a commercial-grade GPS+GLONASS receiver. Using experimentally collected pseudoranges and the RTKLIB, an open-source software-defined GNSS radio receiver operating in the simulation mode, we assessed GNSS positioning performance degradations for various modes of GNSS SDR receiver operation, and identified the benefits of utilisation of multi-GNSS and ionospheric error correction techniques.

In high technologies today, wearable devices have become popular. Wearable technology is a body sensing system that supports application of health observance and tracking through a wearable Global Positioning System (GPS). The design of the patch antennas is highly significant for the brilliance of the wearable patch antennas. This paper focuses on analyzing the bending effect on return loss and frequency between three types of GPS patch antenna. Types of GPS patch antennas that have been designed in this project are with different substrates and different designs. The wearable patch antenna has been designed and analyse using CST software. As a result, able to analysis the reflection coefficient (S11), radiation patterns, and analytical approach for patch antenna bending effect were obtained.
