1. A system for controlling the reception of broadcast entertainment transmissions at a moving receiver station, comprising:

  • a tracking antenna for receiving broadcast entertainment transmissions from a first transmitter having a first coverage area and from a second transmitter having a second, different coverage area;

    an antenna controller coupled to said tracking antenna for pointing said tracking antenna toward at least a first set of predetermined coordinates corresponding to the location of said first transmitter and a second set of predetermined coordinates corresponding to the location of said second transmitter and causing said tracking antenna to track said first set of predetermined coordinates or said second set of predetermined coordinates;

    a region controller coupled to said antenna controller and receiving position information related to the location of said moving receiver station, said region controller storing coverage area data associated with at least said first and second coverage areas;

    said region controller sending a first control signal corresponding to said first set of predetermined coordinates to said antenna controller when said position information and said coverage area data indicates that said moving receiver is within said first coverage area for causing said antenna to track said first transmitter; and

    said region controller sending a second control signal corresponding to said second set of predetermined coordinates to said antenna controller when said position information and said coverage area data indicates that said moving receiver is within said second coverage area for causing said antenna to track said second transmitter.
