Abstract

A method and device for aligning a satellite receiver antenna with a broadcast satellite is disclosed herein. The device includes a receiver for measuring a signal strength from the satellite and issuing commands based on the measurement, a receiver antenna capable of automatically changing its alignment, and a rough alignment indicator located remotely from the receiver for signalling when the antenna is pointed sufficiently toward the satellite allow the receiver to maximize the signal strength by aligning the antenna with the satellite via commands from the receiver. The method includes placing the receiver antenna on a stable surface, manually pointing the antenna in the direction of the satellite until an indicator signals that the antenna is preliminarily aligned, fixing the receiver antenna to the stable surface, and activating a device remote from the antenna to automatically perform final alignment of the antenna with the satellite.

Claims

1. A device for aligning a receiver antenna with a satellite, said device comprising:

a receiver that measures a signal strength value of a signal received from said satellite and issues commands based on said signal strength value;

a receiver antenna in communication with said receiver for receiving said signal from said satellite, said receiver antenna being adapted for electronic alignment with said satellite in response to said commands issued by said receiver, the electronic alignment occurring without physical movement of the receiver antenna; and

an indicator located in proximity to the receiver antenna, said indicator signalling when said receiver antenna is sufficiently aligned with said satellite to permit said antenna to electronically align itself with said satellite.

2. The device as recited in claim 1 wherein said receiver antenna further comprises a phased array antenna.

3. The device as recited in claim 1 wherein said receiver antenna further comprises a parabolic dish fixed to a mounting device including a motorized alignment device in communication with said receiver.

4. The device as recited in claim 1 wherein said indicator further comprises a tone emitting device.

5. The device as recited in claim 1 wherein said indicator further comprises a light emitting device.

6. The device as recited in claim 5 wherein said indicator is mounted on said receiver antenna.

7. A device for aligning a receiver antenna with a satellite, said device comprising:

an antenna that receives a signal from a satellite;

a receiver coupled to the antenna and for electronically aligning said antenna with said satellite after the antenna has been roughly aligned with the satellite and without requiring further physical movement of the antenna;

a rough alignment indicator in communication with said receiver and located in proximity to said antenna, said indicator generating a sensible signal of a first duration when said antenna is in rough alignment with the satellite; and

a user interface in communication with said receiver.

8. The device as recited in claim 7 wherein said rough alignment indicator is mounted on said receiver antenna.

9. The device as recited in claim 7 wherein said receiver antenna further comprises a phased array antenna.

16. The device of claim 7 wherein the user interface includes a signal strength indicator and at least one control switch to initiate electronic alignment of said antenna.

17. The device of claim 7 wherein said sensible signal is auditory.

18. The device of claim 7 wherein said sensible signal is visual.

10. A method of aligning an antenna with a satellite, said method comprising the steps of:

providing an antenna and an indicator located in proximity to said antenna;

securing said antenna on a mounting surface;

physically moving said antenna without removing said antenna from the mounting surface until said indicator signals that said antenna is preliminarily aligned with said satellite;

stabilizing said antenna to prevent further physical movement thereof; and

activating a device remote from said antenna to automatically perform final alignment of said antenna with said satellite without further physical movement of the antenna.

11. The method as recited in claim 10 wherein said receiver antenna further comprises a phased array antenna.

12. The method as recited in claim 10 wherein said step of activating a device remote from said antenna to automatically perform final alignment of said antenna with said satellite further comprises selecting an alignment procedure through a user interface.

13. The method as recited in claim 10 wherein said indicator further comprises a light emitting device.

14. The method as recited in claim 10 wherein said indicator further comprises a tone emitting device.

15. The method as recited in claim 10 wherein said indicator is mounted on said receiver antenna.

19. The method as recited in claim 10 wherein the step of stabilizing is permanent.

20. An apparatus for receiving communication signals from a satellite comprising:

an antenna for receiving electromagnetic signals from a satellite, the antenna being movable to facilitate rough alignment with the satellite;

an antenna controller coupled to the antenna for electronically steering the antenna into final alignment with the satellite without further physical movement of the antenna; and

an indicator associated with the antenna, the indicator generating a sensible output when the antenna is in rough alignment with the satellite.

21. An apparatus as defined in claim 20 wherein said antenna comprises a phased array antenna.
