Method for determining distance between beacons arranged along railway track of railway network, involves determining distance between beacons based on determined topography data, mathematical motion model, and maximum allowable period

摘要

The method involves obtaining (101) maximum allowable position error for determining current position of rail vehicle on railway track by using satellite navigation. A topography data indicating velocity profile of railway track is provided (102). A mathematical motion model (103) is provided for running of rail vehicle. A maximum allowable period is determined (104) based on obtained maximum allowable position error. A distance between beacons is determined (105) based on determined topography data, mathematical motion model, and maximum allowable period. An independent claim is included for a device for determining distance between beacons arranged along railway track of railway network.
