1. A system for satellite communication, the system comprising:

  • (a) one or more antenna units configured for receiving and transmitting electromagnetic radiation at one or more frequency ranges;

    (b) a modem unit connected to the one or more antenna units and configured for de-modulating input signals received by said one or more antenna units to electronic data and modulating output electronic data to signals in one or more predetermined frequency ranges to be transmitted by said one or more antenna units;

    (c) a processor unit connected to said one or more antenna units and to said modem unit, the processor unit comprising;

    i) an antenna orientation optimizer module configured and operable for varying azimuth and/or elevation of signal transmission and reception of said one or more antenna units; and

    ii) a network registration module configured and operable for registering the system to a communication network, said registering comprising;

    selecting a free private communication channel from a list of channels provided by the network, generating a signal comprising a selected sequence for transmission to a hub through the satellite, and configured and operable to be responsive to an appropriate notification signal from the hub in said private communication channel; and

    iii) an initializing module, wherein the initializing module is configured and operable for detecting a common control signal from a network, said detecting comprising;

    identifying available regional hub stations from a predetermined list of network hub stations, locating at least one satellite associated with at least one of said available regional hub stations;

    determining data on corresponding direction and frequency of a common control channel, and providing said direction and frequency data for each of said at least one satellite to the antenna orientation optimizer module; and

    providing the frequency data to the modem unit with an indication of said frequency for a corresponding received signal in said common control channel;

    wherein the modem unit is configured and operable to be responsive to a preamble beacon signal and to adjust frequency of the input signals in accordance with data received in said preamble beacon signal.
