It highlights the major issues that designers need to resolve during the development of GNSS-based systems requiring a certain level of confidence on the position estimates. Although it follows a general approach, the final chapters focus on the application of GNSS integrity to rail transportation, as an example. By describing the main requirements in the context of train position function, one of which is the safe function of any train control system, it shows the critical issues associated with the concept of safe position integrity. In particular, one case study clarifies the key differences between the avionic domain and the railway domain related to the application of GNSS technologies, and identifies a number of railway-signaling hazards linked with the use of such technology. Furthermore, it describes various railway-signaling techniques to mitigate such hazards to prepare readers for the future evolution of train control systems, also based on the GNSS technology. This unique book offers a valuable reference guide for engineers and researchers in the fields of satellite navigation and rail transportation. 000838755 588__ $$aOnline resource; title from PDF title page (viewed April 25, 2018). 000838755 650_0 $$aRailroads. 000838755 650_0 $$aGlobal Positioning System. 000838755 7001_ $$aLo Presti, Letizia,$$eeditor. 000838755 7001_ $$aSabina, Salvatore,$$eeditor. 000838755 77608 $$iPrint version:$$tGNSS for rail transportation.$$dCham, Switzerland : Springer, [2018]$$z3319790838$$z9783319790831$$w(OCoLC)1028616998 000838755 830_0 $$aPoliTO Springer series. 000838755 852__ $$bebk 000838755 85640 $$3SpringerLink$$uhttps://univsouthin.idm.oclc.org/login?url=http://link.springer.com/10.1007/978-3-319-79084-8$$zOnline Access$$91397441.1 000838755 909CO $$ooai:library.usi.edu:838755$$pGLOBAL_SET 000838755 980__ $$aEBOOK 000838755 980__ $$aBIB 000838755 982__ $$aEbook 000838755 983__ $$aOnline 000838755 994__ $$a92$$bISE
