3
MAGNET BMulti-modal Approach for GNSS 1 in
European Transport (Rail)

• To verify accuracy and availability of GNSS train
  positioning platforms
• Sensor Fusion
• Field Tests

4
APOLOAdvance Position Locator System

• To test the GPSEGNOS receiver hybridised with
  inertial sensors
• Two Classes of prototype
• - APOLO-SSA (Standard Service
  Accuracy)50-100 m
• - APOLO-HA (High Accuracy)5-10 m
• Dynamic Test
• - GPS hybridised with odometer and
  gyrometer 4.8 m at 95 confidence
• - GPSEGNOS 1m at 95 confidence

5
Galileo Projects

• GALA
• - Analysis of rail applications and market
  for Galileo
• SAGA
• - Standardisation activities for Galileo in
  rail domain
• GALILEI
• - Specify Galileo user needs in the rail
  domain
• Galileo research development within EC FP 6

6

• Review and document the research and activities
  in relevant telematics areas, identify the issues
  that needed to be addressed and make
  recommendations for future research or other
  activity
• Radio Navigation Opportunities in Rail
• - Movement Control (traffic), TGV Location
  ID, Rail Maintenance, Emergency Response
• - Tracking Rolling Stock, Resource
  Management, Passenger Information
• - Formation of Digital Maps and Digital
  Description of Railway Environment, etc.

Main Requirements for Railway Application
8
GADEROSA Galileo Demonstrator for Railway
Operation System

• Definition of a common functional core and a
  common interface for train location functionality
  integrated into the ERTMTS/ETCS
• Verification of feasibility of the application of
  a GNSS locator to support a Traffic Monitor
  Central
• Development of a common test bed for the
  principal performance of the train locator
  devices

9
INTERGRAILIntegrity Improvement for Rail

• ECA project to study the feasibility to
  integrated GNSS-1-based positioning
  into-ERTMS/ETCS
• Positioning accuracy with EGNOS without serious
  multi-path and shadowing is
• - sufficient for rural line (single line as
  most part)
• - insufficient for areas with many parallel
  tracks
• Aiding sensor is necessary
• EGNOS should be augmented by terrestrial
  communication in mountain area
• Accurate route atlas is key element of integrity
  performance

10
LOCOPROLLow Cost Satellite Based Train Location
System for Signalling and Train Protection for
Low Density Railway Lines

• Objectives
• - An innovative low life cycle cost fail
  satellite based train positioning solution
• - A low life cycle cost signalling system
  for LDT lines
• Functions to be fulfilled
• - Satellite-based train detection/positionin
  g
• - Spacing out of train along the line by
  digital track data base
• - Control of points and signals in stations
• - Automatic train protection/control
