A method of controlling access of a terminal (2) to a satellite communications network (6), comprising the steps of: storing location data in said terminal (2) defining at least one location (X) at which said terminal may communicate on a first basis; comparing at said terminal (2) said location data and position data defining the position (Y) of said terminal; and controlling said terminal (2) to grant access to said satellite communications system on said first basis or not, depending upon said comparison. |
