Demonstrate the integrity of train positioning at the railway

Short Description

Train location systems have to satisfy high standards regarding reliability, safety, availability
and integrity of positional data since erroneous position data might result in severe damage.
Existing location systems often rely upon not only train based systems but also on track side
installations. In many rural areas, radio based communication systems also play a significant

The proposed project focuses on utilizing satellite based navigation technology for deriving
an integrated positioning system (using GNSS augmented by on-train sensors) that is independent
from track-side installations. Focusing on the deployment and use in rural areas, the
derived system will incorporate tailor-made integrity calculations that are suited for enabling
subsequent certification processes.

The project aims to provide system design and safety concepts elements as well as a demonstrator
that are derived by strict adherence to processes applying formal certification
requirements (TRL level 2 - 4).

Regional train operators will be participating by in kind contributions in order to support requirements
analysis, system design and final validation of the demonstrator to be developed
and thus, a user driven development is ensured.

Results from this activity will enable the development of further products and/or services that
increase the spectrum of train related technologies such as GNSS-based operation/
activation of level crossings und thus facilitate benefits for the general public. Such systems
will help to significantly reduce costs e.g. for the modernization of level-crossing installations
by reducing infrastructure cost and – at the same time – allow for increased safety in
activation and operation of these installations.
