A method for controlling navigation of an unmanned vehicle , wherein the method comprises: a) establishing a communication between an electronic device for piloting the vehicle, called ground control station GCS, and the vehicle ; b) if the communication has been successfully established, the vehicle receiving from the GCS a request to access the vehicle and a GCS identifier ; c) authenticating in the vehicle an user of the GCS from at least the user identifier and of the GCS identifier received from the GCS and if the authentication has not been successful, denying access to the vehicle to said user and ending the method; d) receiving in a server called Centralized Control System of Unmanned Vehicles, CCSU, through a mobile communications network, a vehicle identifier and the user identifier; e) authenticating in the CCSU the user and the vehicle based at least on their identifiers and if this authentication has been successful, sending a successful authentication response from the CCSU to the vehicle and if the authentication has not been successful, ending the method; f) the CCSU receiving a request for authorisation of the vehicle , including the characteristics of the trajectory for which the vehicle is requesting authorization, the CCSU determining if said route is authorized and if it is authorized, sending an authorized trajectory message to the vehicle and monitoring the trajectory of the vehicle and if it has not been authorized, ending the method; g) if during the monitoring of the trajectory, any trajectory condition not allowed by the CCSU occurs, the CCSU sending a message to the vehicle refusing the authorization for the trajectory. a) establishing a communication between an electronic device for piloting the vehicle, called ground control station GCS, and the vehicle ; b) if the communication has been successfully established, the vehicle receiving from the GCS a request to access the vehicle and a GCS identifier ; c) authenticating in the vehicle an user of the GCS from at least the user identifier and of the GCS identifier received from the GCS and if the authentication has not been successful, denying access to the vehicle to said user and ending the method; d) receiving in a server called Centralized Control System of Unmanned Vehicles, CCSU, through a mobile communications network, a vehicle identifier and the user identifier; e) authenticating in the CCSU the user and the vehicle based at least on their identifiers and if this authentication has been successful, sending a successful authentication response from the CCSU to the vehicle and if the authentication has not been successful, ending the method; f) the CCSU receiving a request for authorisation of the vehicle , including the characteristics of the trajectory for which the vehicle is requesting authorization, the CCSU determining if said route is authorized and if it is authorized, sending an authorized trajectory message to the vehicle and monitoring the trajectory of the vehicle and if it has not been authorized, ending the method; g) if during the monitoring of the trajectory, any trajectory condition not allowed by the CCSU occurs, the CCSU sending a message to the vehicle refusing the authorization for the trajectory. <EOS>
