D21.2: System requirements of ASTP system
FP2-R2DATO advances rail safety and efficiency by developing the Advanced Safe Train Positioning (ASTP) system, a modular and scalable solution designed to deliver absolute positioning with higher accuracy of speed and location. In line with this goal, deliverable 21.2 formalises the system requirements derived from the operational analysis, while integrating state-of-the-art requirements for safe onboard electronic equipment. The ASTP concept supports a wide range of CCS and non CCS functions, including ATP, ATO, ATS/TMS and TCMS, enabling energy savings, optimised headways and a reduction of the trackside infrastructure. This deliverable was developed in two steps. The first versions highlighted some open issues about the CCS-OB architecture or specification , which were later clarified through technical notes and feedback from WP members. While final resolution lies with the broader System Pillar, D21.2 collects the clarified requirements and provides a TRL 6 framework for future integration. To conclude, the document highlights ASTP’s role in supporting interoperable applications both onboard and trackside, ensuring alignment with operational needs and analysis of required system performance for the system.
How it brings us closer to achieving better rail for Europe: The Advanced Safe Train Positioning (ASTP) system defines a modular and scalable approach to absolute train positioning, delivering more accurate speed and location data. By supporting CCS and non CCS functions such as ATP, ATO, ATS/TMS and TCMS, it enables optimised headways, energy savings and reduced reliance on trackside equipment. Through harmonised requirements and clarified system capabilities, it strengthens interoperability and provides a TRL 6 framework. This contributes to make rail operations safer, increase traffic capacity and use energy more sustainably, leading to a rail system that is more reliable, efficient and better connected across Europe.
