Abstract
A method for certifying the geolocation of a receiver, including, prior to said certification, receiving, at predetermined times, in addition to the geolocation signals emitted by a plurality of emitters and used to compute said geolocation, a predetermined number of additional electromagnetic signals emitted by the same emitters and including data used to authenticate the geolocation, the method comprising determining the authenticity of the geolocation on the basis of the additional electromagnetic signals.
Claims8
A system, comprising
- a plurality of emitters, each designed to emit electromagnetic signals used for geolocation, called “geolocation signals”,
- at least one receiver being an inspection terminal designed to receive the electromagnetic signals emitted by the emitters and configured so as to:
- determine the position of the receiver based on the geolocation signals, and
- verify the authenticity and the validity of the geolocation, and
- one or more jamming stations communicating with or linked to said at least one inspection terminal and being configured to jam one or more electromagnetic signals sent by at least one of the emitters after a fraudulent geolocation signal has been detected,
- the one or more electromagnetic signals that are jammed are limited to a configurable subset of electromagnetic signals following the fraudulent geolocation signal that was detected.
