Project Objectives
The EGNOS Controlled Railway Equipment (ECO-RAIL)
project was one of several GNSS-1 Rail User Navigation
Equipment projects dealing with the implementation
of satellite navigation into the railway domain to
demonstrate the feasibility and benefits of GNSS.
The ECO-RAIL project was aimed at designing and testing a
positioning system which is based on satellite navigation
in a safety critical railway application. In order to
show the benefit of the innovation, the project focused
on the specific application of the control of automatic
level crossings (ALX): Based on an on-board navigation
unit employing multi-sensor technique, it is possible
to activate an ALX via a radio link. Consequently, there is reduced need for cost-intensive track-side facilities,
especially
for positioning (e.g. track circuits, beacons) and for
signal transmission (cables).
After the specification of requirements and technical delineation, the ECO-RAIL project comprised the design
and test of the on-board equipment as well as a demonstration
on a pilot track in the Austrian province Upper-Austria. The demonstration aimed
at the evaluation of the system performance, regarding the
efficiency of the developed localisation compared to the existing
hardwired localisation system.

and transmits an activation request to the control system.
The control system closes the level crossing and triggers
the information to pass.
