    GNSS Train Position Verification by the Help of Parametrical PIM Algorithms

  • Original language description

    Today there exists several methods of the train position determination. Research in The Global Navigation Satellite Systems (GNSS) area shows, that it is good to use satellite navigation for this purpose. Described algorithms monitor the position integrity of the GNSS receiver. The aim of these algorithms is to verify that the GNSS position corresponds to the given train track and to find out that obtained GNSS position complies with safety requirements ? Safety Integrity Level (SIL) ? for given probability of undetected failure. The train track can be defined by a parametric equation, analytical function or discrete timely equidistant set of position coordinates. This paper is mainly devoted to the parametrical algorithms. All of described parametrical algorithms are based on a statistical model with constraints, threshold domains computation and test of fit.

    Ověření GNSS polohy vlaku pomocí paramertických PIM algoritmů

  • Czech description

    V současnosti existuje řada metod pro určení polohy vlaku na trati. Výzkumy v oblasti Globálních Navigačních Satelitních Systémů (GNSS) ukazují, že je výhodné využívat satelitní navigaci i pro tento účel. Popisované algoritmy monitorují integritu GNSS polohy. Cílem algoritmů je ověřit, zda GNSS poloha koresponduje s danou předpokládanou tratí vlaku, tedy zjistit, zda získaná GNSS poloha splňuje požadavky na bezpečnost ? Safety Integrity Level (SIL) pro danou pravděpodobnost nedetekované chyby. Trať vlaku je definována parametrickými rovnicemi. Popisované algoritmy jsou založeny na statistických modelech s podmínkami, oblastech necitlivosti a testech dobré shody.
