  • ON EGNOS MONITORING IN LOCAL CONDITIONS

    Any SBAS system should deliver to the user corrections to pseudoranges as well as information about the system integrity. In theory, as soon as the system is permanently monitored by RIMS stations, it is impossible to deliver the fault information to the user. However many observations shows that accuracy of EGNOS service in the same time are different in different places, which shows the influence of local conditions on them....

  • Accuracy and Availability of EGNOS - Results of Observations

    Publication

    According to SBAS concept the user should receive timely the correct information about the system integrity and corrections to the pseudoranges measurements, which leads to better accuracyof coordinates. In theory the whole system is permanently monitored by RIMS stations, so it is impossible to deliver the faulty information to the user. The quality of the system is guaranteed inside the border of the system coverage however in...

    Publication

    Positioning accuracy is very important in many areas. EGNOS improves accuracy, but

  • Has EGNOS its own place in maritime navigation?

    Publication

    - Year 2015

    GNSS (in fact it usually means GPS) is at the moment the fundamental means of positioning for any variants of navigation. However some attributes of it can be not sufficient for every users or in some tasks, so there are any cases when this system needs support. From the mariner point of view pure GPS properties perfectly fulfils expectations of sailors at the open sea, however there are lot of cases, when accuracy of the system...

  • EGNOS-based GNSS receiver for precise positioning in restricted areas

    Publication

    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...

  • THE RESEARCH ON EGNOS SYSTEM IN CONTEXT OF THE ABILITY TO DETERMINE THE SHIP’S HULL SPATIAL ORIENTATION

    Publication

    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...

  • Badanie możliwości określania parametrów ruchu statku za pomocą systemu EGNOS

    Publication

    - Logistyka - Year 2014

    W niniejszym artykule zaprezentowano badania dokładności względnej wyznaczeń współrzędnych pozycji za pomocą trzech jednorodnych odbiorników systemu EGNOS. Ich celem było sprawdzenie możliwości wykorzystania systemu do określania parametrów ruchu statku, w tym kątów orientacji przestrzennej kadłuba. Opisano podstawy teoretyczne, przebieg eksperymentu oraz wyniki analiz zarejestrowanych danych. Badania przeprowadzono na morzu latem...

  • The Proposal to “Snapshot” Raim Method for Gnss Vessel Receivers Working in Poor Space Segment Geometry

    Publication

    Nowadays, we can observe an increase in research on the use of small unmanned autonomous vessel (SUAV) to patrol and guiding critical areas including harbours. The proposal to “snapshot” RAIM (Receiver Autonomous Integrity Monitoring) method for GNSS receivers mounted on SUAV operating in poor space segment geometry is presented in the paper. Existing “snapshot” RAIM methods and algorithms which are used in practical applications...
