• Nowa metoda oceny dokładności wyznaczeń GNSS na potrzeby monitoringu pojazdów

  Publikacja

  • A. Nowak

  - Logistyka - Rok 2014

  Zdolność systemu do ostrzegania użytkownika o tym, że błąd wyznaczonych współrzędnych przekroczył dozwoloną wartość, nazywa się wiarygodnością[4]. W chwili obecnej ani GPS, ani GLONASS nie zapewniają monitoringu wiarygodności, w związku z tym istnieje niepewność dotycząca rzeczywistego położenia obiektu. Sytuacja taka jest niedopuszczalna wszędzie tam, gdzie błąd gruby wyznaczeń współrzędnych może doprowadzić do poważnych konsekwencji...

  - JOURNAL OF NAVIGATION - Rok 2017

  Nowadays, the most widely used method for estimating location of autonomous vehicles in real time is the use of Global Navigation Satellite Systems (GNSS). However, positioning in urban environments using GNSS is hampered by poor satellite geometry due to signal obstruction created by both man-made and natural features of the urban environment. The presence of obstacles is the reason for the decreased number of observed satellites...

  The spatial correlation between different stations for individual components in the regional GNSS networks seems to be significant. The mismodelling in satellite orbits, the Earth orientation parameters (EOP), largescale atmospheric effects or satellite antenna phase centre corrections can all cause the regionally correlated errors. This kind of GPS time series errors are referred to as common mode errors (CMEs). They are usually...
