description A method for authentication of GNSS messages by an authentication transmitter apparatus comprising a reference receiver, an authentication server and an authentication transmitter. The method comprises: receiving, by the reference receiver, a plurality of navigation messages from a plurality of GNSS satellites; hashing, by the authentication server, the navigation messages to create a plurality of hashed messages; creating, by the authentication server, a table comprising the plurality of hashed messages; signing, by the authentication server, the table to create a signed table comprising the hashed messages and acryptographic signature, and transmitting, by the authentication transmitter, the signed table to an authentication receiver apparatus.
