Method and device, and the network for the authentication of the position of a receiver of satellite navigation on the basis of the signals of the navigation messages

摘要

This document describes a method of processing of data that is to be detected and stored in a device, the flow of navigation messages received in a receiver from the navigation systems by satellite or terrestrial and its comparison with the original data transmitted by the navigation system with respect to a time reference which is common to all the signals. The recorded creates a signature that is unique for each instant, and each position over the entire surface of the service (earth or any other planet or celestial body). The result of the processing of data to a particular point of the earth is used to validate the position and the reference time delivered by the navigation receiver.
