EGNOS - the first European satellite navigation system is a join project of the European Space Agency, Eurocontrol, European Commission and represents the fist step to towards Galileo - autonomous navigation satellite system of the 2nd generation (GNSS-2). The system Operational Readiness Review (ORR), took place in June 2005 and resumed of more than eight years of studies, works, leaded by ESA and an industrial consortium with Alcatel Space as the Prime Contractor. The Initial Operations Phase has therefore started in July 2005 as an effect of successful negotiations between ESA and European Satellite Services Provider. During the last years many different test, trials and measurement campaigns have been done in positioning, navigation, time services and other application for improving different characteristics of EGNOS [4, 5]. Some of them were also realised in Poland [1, 2] and observed accuracy confirm high system performances. Poland is at the edge of the system coverage then the system disturbances could be more probable than in the central part of the Europe. Presented paper reports final results of the, long-term static measuring campaigns, which were done before the EGNOS System Test Bed (ESTB) ending. Two-week accuracy analyses were done and the position error statistic distributions of system were also compared with the classical DGPS based on LF/MF reference station.

In the year 2005 the EGNOS enters the Operational Readiness Review phase becoming available for users in its almost full capability. It may be expected that very soon EGNOS will find significant interest among many users and will find many applications all over the Europe. The paper presents the summary of the tests of satellite positioning with using EGNOS (ESTB) signal conducted by author in the area of the Polish coast of the Baltic Sea during several years since 2001 till now. The results of conducted tests show the EGNOS (ESTB) performance at the edge of the nominal system coverage, verifying, in the experimental way, the predicted system accuracy and the efficiency of WADGPS EGNOS algorithms in this area. Additionally, the comparison of the results obtained during the subsequent years of the system development shows the gradual improvement in system performance coming with increased number of RIMS and the evolution from the EGNOS System Test Bed to the fully capable EGNOS.

The European Geostationary Navigation Overlay Service (EGNOS) augments the open public service offered by the GPS in Europe making suitable the use of GPS for safety critical applications. EGNOS is designed according to the same standard [ICAO SARPs, 2018] such as US WAAS, Japanese MSAS, GAGAN in India, SDCM in Russia and KAAS in South Korea and provides over Europe both corrections and integrity information about the GPS system. As the European SBAS, EGNOS offers three services: Open Service, Safety-of-life Service and EDAS. In general, the EGNOS Safety-of-life (SoL) Service is intended for transport applications in different domains (and currently in use by Aviation) where lives could be endangered if the performance of the navigation system is degraded below specific accuracy limits without giving notice in the specified time to alert. This requires that the relevant authority of the particular transport domain determines specific requirements for the navigation service based on the needs of that domain. Even if the main objective of the SBAS systems is the civil aviation community, the advantages provided by this technology are very useful to users from other domains. In this sense, a new EGNOS service for maritime is currently under development with the objective to complement the existing maritime radionavigation systems (e.g. DGNSS) in the European region for enhanced accuracy and integrity information where there is no back-up infrastructure or in poorly covered environments. One of the steps needed for the development of this new EGNOS maritime service is the definition of a minimum set of recommendations for receiver manufacturers to provide them with a clear view on how to design their SBAS receivers to be compliant with the requirements defined for such a service. For that, EC, GSA, ESA and ESSP SAS have been working together since 2016 to develop guidelines for manufacturers for the implementation of SBAS in shipborne receiver. These guidelines, developed in the frame of the SBAS Working Group created in the Special Committee (SC) 104 on Differential Global Navigation Satellite Systems (DGNSS) of Radio Technical Commission for Maritime Services (RTCM), define a minimum set SBAS messages to be compliant with the International Maritime Organization (IMO) Resolution A.1046 and additionally provide a test specifications. This paper presents a summary of these SBAS guidelines as well as the preliminary list of tests that must be fulfilled to be compliant. Additionally, a preliminary performance assessment of the EGNOS maritime service based on IMO Res. A.1046 (27) for a 24-months period during 2016, 2017 and 2018 is presented. The performance parameters are calculated using real data to show what level of performance was attained by EGNOS. The assessment was done using both EGNOS ground monitoring stations (RIMS) and fault-free receivers, based on these guidelines, fed with actual data. The performance is shown for each performance parameter defined in the IMO Res. A.1046 (27) and for navigation in Ocean Waters and coastal waters, harbour entrances and harbour approaches. The paper also includes Service Coverage maps representing where EGNOS maritime service based on IMO Res. A.1046 (27) is fulfilling the requirements. Furthermore, GSA and ESSP, with the collaboration of The Norwegian Coastal Administration and Hurtigruten Cruises, carried out a GNSS data collection campaign of 10 days along the Norwegian coast with a trajectory through Trondheim to Kirkenes and Kirkenes to Bergen in February 2018. The aim of this data campaign was to assess EGNOS performance at user level in the maritime domain at high latitudes in Europe. The data campaign includes the navigation outside the MT27 region defined in EGNOS at that moment (70ºN). A performance assessment of EGNOS using some commercial receivers and a software receiver in line with the SBAS guidelines will be presented, showing the observed accuracy and availably results of the EGNOS solution.

Ionosphere coverage is likely to be a driver for the EGNOS coverage area. Hence, a study considering a dedicated ionosphere algorithm to improve the ionosphere coverage area has been conducted. The logic of the study is the following: the accuracy of the GPS signal depends mainly on the total electron content (TEC). At two close points, TEC changes in time in a very similar way; these are region dependent variables. This correlation decreases with growing distance between the observation points and is anisotropic. Based on TEC variogram analysis, the specific algorithm has been developed. This specific algorithm is presented and discussed.

The transport sector requires efficient and accurate traffic management systems in airspace, on land and at sea. European Geostationary Navigation Overlay Service (EGNOS) may be part of these systems. However admission to its use in Poland requires analysis whether it fulfil international standards. This paper presents such verification of the EGNOS usefulness for: air, sea, road and rail Polish transport. Therefore, conducted a characterization and analysis of four parameters of the signal (accuracy, integrity, continuity and availability) based on data from the EGNOS Data Collection Network in the years 2011-2012. Monitored parameters were compared with current international requirements for the signals of satellite systems in force in the various types of transport. This allowed to determine whether the EGNOS system can be used in them.

Sektor transportu wymaga efektywnych i dokładnych systemów zarządzania ruchem w przestrzeni powietrznej, na lądzie i morzu. Europejski Satelitarny System Wspomagania (EGNOS) może być ich częścią. Jednak dopuszczenie do jego wykorzystania w Polsce wymaga uprzedniej analizy pod względem spełniania międzynarodowych standardów. Niniejszy artykuł przedstawia taką weryfikację przydatności systemu EGNOS na potrzeby polskiego transportu: lotniczego, morskiego, klejowego i drogowego. W tym celu scharakteryzowano i przeanalizowano cztery parametry sygnału systemu (dokładności, wiarygodności, ciągłości i dostępności) na podstawie danych pochodzących z bazy danych EGNOS Data Collection Network z lat 2011-2012. Monitorowane parametry zostały następnie porównane z obowiązującymi międzynarodowymi wymaganiami dla sygnałów systemów satelitarnych w poszczególnych rodzajach transportu. Pozwoliło to na ustalenie, czy system EGNOS może być w nich wykorzystywany.

Any SBAS system, as soon as it is permanently monitored by Earth stations, should deliver to the users correct information about quality of the augmented system. According to many sources of information, among them observations of authors, present accuracy of EGNOS service has accuracy about 1,5m (95%), but availability of the service is still controversial. First of all the quality of the system is guaranteed only inside the border of the system coverage which still do not affect all territory of European Union, however observed accuracy at times is better outside this area than next door to the RIMS station. In addition there are evidences that availability has random character and essential differences as well as lack of correlation of this parameter in the different point of observations has been observed. So in author’s opinion Local Monitoring of EGNOS service can contribute to better confidence of local users, especially in critical operations, like for example berthing of big ships or landing operations with EGNOS procedures. The example of EGNOS monitor which is working in real time and performed by the authors will be presented.

The European Geostationary Navigation Overlay Service (EGNOS) thanks to geostationary satellites covers an area of whole Europe, including Baltic and North Sea. It allows to fix the coordinates of object position with typical absolute accuracy of 1,5 m. Previous research have shown that relative accuracy is usually higher than absolute one [Nowak A., 2010; Nowak A., 2011], so probably it could be possible to use EGNOS to determine direction in space. The research described in the paper concerned relative accuracy of three homogeneous EGNOS receivers, in context of the ability to determine the ship’s hull spatial orientation. Theoretical basis, the process of the experiment and the results of recorded data analysis were described. The research were conducted in the summer of 2014. Three homogenous Leica Viva series receivers were used. They were configured to receive a differential messages of the EGNOS system. Recorded data were analyzed in context of fixes relative accuracy. On the basis of achieved results, a conclusion about the possibility of construction the meas-urement system for the automatic determination of the ship’s hull spatial orientation angles in real time was drawn. The further research directions were pointed out, too.

To pozwala wyznaczać współrzędne pozycji obiektów z dokładnością absolutną rzędu 1,5 m. Wcześniejsze badania dowiodły, że względna dokładność jest zwykle wyższa niż absolutna [Nowak A., 2010; Nowak A., 2011], wobec czego postawiono hipotezę, że można by użyć EGNOS do określania kątów orientacji obiektu w trzech wymiarach. Badania przedstawione w artykule dotyczyły względnej dokładności trzech jednorodnych odbiorników EGNOS w kontekście możliwości określania orientacji przestrzennej kadłuba statku. Opisano teoretyczne podstawy, realizację eksperymentu i wyniki analizy zarejestrowanych danych. Badania były prowadzone latem 2014 roku. Użyto trzech jednakowych odbiorników serii Leica Viva, które skonfigurowano tak, by otrzymać informacje różnicowe. Zarejestrowane dane analizowano w kontekście względnej dokładności wyznaczeń.

Positioning accuracy is very important in many areas, whereas the typical GPS receiver accuracy is often not sufficient. The European Geostationary Navigation Overlay Service (EGNOS), Europe’s first venture into satellite navigation, improves the open public service offered by the Global Positioning System (GPS). As a satellite navigation augmentation system, EGNOS improves the accuracy of GPS by providing a positioning accuracy to within 3 meters. In this paper we present GNSS receivers based on EGNOS, dedicated for precise positioning in restricted areas of continental shelf performance. The article presents some results regarding position accuracy, obtained for a few receivers in that context.

The European Geostationary Navigation Overlay Service (EGNOS) is the first pan-European satellite navigation system. EGNOS makes GPS suitable for safety critical applications such as flying and landing an aircraft. To use EGNOS in aviation the system monitoring and validation in certain localization in needed, as well as official flight procedure design and certification. According to these rules, several GNSS/EGNOS stations located at Polish airfields are currently operational, permanently collecting EGNOS data. The newest monitoring station was established and put into operation at the Polish Air Force Academy in Dęblin in the beginning of 2016. Dęblin is situated in central-eastern part of Poland (south of Warsaw). Until recently this area was on the edge of official coverage of EGNOS services, especially Safety-of-Life (SoL) service. Latest official documents declare that theoretically the eastern part of Poland is currently fully covered with EGNOS SoL service, however this still needs to be practically confirmed. New station equipped with the newest Javad Delta-3 GNSS receiver will allow to evaluate practical quality of EGNOS in this area. The article presents preliminary results of EGNOS Safety of Life service performance in Dęblin in comparison to the results obtained in Olsztyn which is situated in north-eastern part of Poland (north of Warsaw). The main parameters characterizing navigational system i.e. accuracy, integrity, continuity and availability were analyzed in detail. The results can be the basis to assess the possibility of implementation of the EGNOS APV approach and landing procedures in Dęblin and Olsztyn.
