The purpose of the Operational Scenario definition is to specify operations, scenarios and environmental conditions for a train run under which the system under consideration has to function according to the specification. The definition of scenarios includes standard situations, but also challenging environments and situations which might define design parameters and impact the key performance of the localisation system. The operational scenarios might be influenced, for example, by conditions and parameters such as a maximum length of GNSS shading, GNSS multipath or non-line of sight (NLOS) effects or challenging manoeuvres for inertial measurement units (IMUs) including shock and vibration. This deliverable is to be used by the project in particular by WP4 for data acquisition and testing.
