Abstract
Because satellite positioning has many advantages, such as low cost, good real-time performance and no accumulative error (Blomenhofer in Acta Astronaut 54:965–968, 2004 [1]), it is widely used in automobile navigation (Skog and Handel in IEEE Trans Int Transp Syst 10(1):4–21, 2009 [2]) and electronic map software (Zhang et al. in IEEE Trans Int Transp Syst 9(4):666–677, 2008 [3]). In addition, satellite positioning technology is also applied to train positioning and tracking by replacing the track circuit and radio frequency positioning technology that have been used in the past (Santos et al. in IEEE Trans Int Transp Syst 6(2):244–258, 2005 [4]). The adoption of satellite positioning technology can greatly reduce the installation and maintenance costs of the wayside equipment (Raymond et al. in Railway Gaz Int 160(12):835–837, 2004 [5].
