Satellite Technology for Advanced Railway Signalling

The aim of  STARS  project  is  to develop a universal approach to predict the achievable GNSS performance  in  a  railway  environment,  especially  for  safety  critical  applications  within ERTMS  (The  European  Railway  Traffic  Management  System).

The  result  will  allow  the railway  companies  to  guarantee  the interoperability  between  the  equipment  provided  by different  GNSS  suppliers.

This  shall  make  it  possible  to  include  GNSS  into  ERTMS,  while  maintaining both the safety of the system and the interoperability to fill the technology gaps in order to reach a cost-efficient satellite-based ERTMS.

As a result of the project it shall be possible to predict performance of GNSS in the railway environment in regards to accuracy, availability and safety. This shall be possible for specific locations or sections along railway lines, and based on using a receiver compliant with  the guidelines as defined in the NGTC project.
