Claim of US Patent No. 10,194,408

1. A method for establishing a virtual beam for timing synchronization in a satellite communication network, the method comprising:estimating, by an electronic controller, a maximum satellite position error associated with an estimated position of a satellite of the satellite communication network within a satellite location space;
estimating, by the controller, a maximum remote unit position error associated with estimated position of a remote unit that is configured to communicate with the satellite of the satellite communication network, including estimating a gateway travel time error pertaining to an estimated travel time of a signal between the satellite and a gateway of the satellite communication network;
establishing, by the controller, a size of the virtual beam based on the maximum satellite position error, the maximum remote unit position error, and the gateway travel time error; and
creating, with the electronic controller, a virtual map for the virtual beam.
