GCAR– Example


ECOTAXE

GNSS-Based Road User Charging


Certification of GNSS Receivers (GPS, GLONASS) rolled out for collecting the tax related to the use of trucks within the French road networks. An approval to the Receivers (Chains of tax collection) is granted whether the results prove that the taxes will never wrongly claim through the chain tested.
