Reliability Assessment of Supporting Satellite System EGNOS

Analysis of reliability power supply intrusion and hold-up systems presented in the standard PN-EN 50131-1:2009

“…Do najistotniejszych z nich można zaliczyć m. in. wysoką sprawność, miniaturyzację, odpowiednią funkcjonalność, odpowiednie wartości wskaźników niezawodnościowo-eksploatacyjnych [1,17,19], możliwość diagnozowania w poszczególnych stanach eksploatacyjnych z uwzględnieniem jakości informacji [23], odporność na zakłócenia elektromagnetyczne [6,12] i wibracje [3]. Spełnienie tych oczekiwań wymaga znajomości wiarygodnych modeli niezawodnościowo-eksploatacyjnych systemów zasilających.…”

“…Several important criteria are required from power supplies used in electronic safety systems, and in particular in transport systems used in safety,. The most important of them include, among others high efficiency, miniaturization, proper functionality, appropriate values of reliability and operational indicators [1,17,19], ability to diagnose in particular operating conditions with regard to quality of information [23], electromagnetic immunity [6,12] and vibration [3]. Meeting these expectations requires knowledge of reliable reliability and operation models of power systems.…”

Issue of reliability–exploitation evaluation of electronic transport systems used in the railway environment with consideration of electromagnetic interference

“…The model of the process of electronic transport system exploitation will require the reliability–exploitation analysis [23, 24] of the system used in the railway environment where electromagnetic interferences occur. This will allow determination of the dependencies enabling specification of the values of probabilities of the system staying in the emphasised exploitation states.…”

Analysis of Accuracy and Reliability of Different Types of GPS Receivers

“…In the latter case, redundant infrastructure means better tolerance of failures [ 11 , 12 ], through the extension of the transport system. This consequently generates significant maintenance costs [ 13 , 14 ]. Therefore, GPS quality, which depends on DOP (dilution of precision), the number of visible satellites (having a minimum elevation mask of 10–15°), and positioning accuracy [ 1 , 15 , 16 ] fed into a transport system including GPS receivers [ 17 , 18 , 19 , 20 ], is paramount.…”
