Abstract: The present invention belongs to the field of positioning applications, particularly those requiring or benefiting from the use of geographic information and needing a high service or integrity guarantee, such as positioning by means of a satellite navigation system for users and ground vehicles circulating through a network of streets and highways for example. The invention can be used both for critical safety applications and for those entailing legal or contractual responsibilities.

Abstract: An automatic charging system for charging a vehicle for using an infrastructure delimited by a boundary during a charging period Tc based on Global Navigation Satellite Systems (GNSS) location with guaranteed performance. The system includes an onboard receiver with integrity guarantee which, in addition to providing position information, provides additional information relating to the error that can be expected in the position consisting of a health flag (denoting a Healthy/Unhealthy status), and a Radial Protection Level (RPL) relating to the amount limiting the horizontal position error according to one direction and with a probability equal to a known value IRx.
