eCall Testing Using GNSS Simulation

eCall Testing Using GNSS Simulation

eCall is a European initiative intended to bring rapid assistance to motorists involved in a collision anywhere in the European Union. eCall will be mandatory in all new cars sold within EU after April 2018.

It is necessary for automotive manufacturers to develop detailed eCall test procedures for the approval of motor vehicles with respect eCall in-vehicle systems. They need to comply with the standard, which includes specific test configurations that can only be built using GNSS simulation.

eCall Compliance Scenarios

For 5- and 6-Series GPS Simulators

The Spectracom GSG line of GNSS simulators efficiently simulate all the major GNSS constellations needed for testing compliance of critical signal receiving equipment in a variety of eCall scenarios. These are of special interest to vehicle manufacturer or IVS system integrators, and examples include those stated by the European GNSS Agency (GSA):

  • Positioning accuracy under different conditions
  • Time-to-first-fix
  • GNSS receiver sensitivity
  • Re-acquisition performance following signal outages
  • Playing specific static and dynamic trajectory scenarios
  • Changing RF transmit power level manually or remotely sequenced as required by standard
