Abstract

A method in a system having an antenna for tracking and transceiving intelligence bearing signals from/to satellites for use by a multiplicity of devices on an aircraft, and for automatically switching between different satellites while the aircraft is in route. The method includes the steps of retrieving navigational data from systems of the aircraft for use in determining the time and position of the aircraft. The method also determines if a service region of a first satellite is in transition, and if so; it determines if the satellite service overlaps with a second satellite and if the second satellite signal is stronger. If yes, then service from the second satellite is acquired by pointing the antenna to this second satellite and configuring second intelligence signals received from the second satellite. Then, the second intelligence bearing signals are displayed and distributed to devices within the aircraft.

Claims

1. A system for tracking and transceiving intelligence bearing signals from satellites for distribution to a multiplicity of devices on an aircraft, and for automatically switching between different first and second satellites while the aircraft is in route, said system comprising:

a. a first unit responsive to navigational data from systems of said aircraft for determining if a service region of said first satellite is in transition;

b. said first unit also capable of determining if satellite service overlaps with a second satellite, and if said second satellite signal is stronger;

c. a second unit responsive to signals from said first unit for acquiring service from said second satellite by pointing said antenna to said second satellite; and

,

d. a third unit for configuring second intelligence signals transceived from said second satellite for displaying and distributing said configured second intelligence signals transceived from said second satellite to devices within said aircraft.

2. The system according to claim 1 further including a unit responsive to said navigational data for determining the right to transceive said intelligence bearing signals within various geographical regions by applying regulatory criteria from a database containing such information.

3. The system according to claim 1 further including a database storing event triggers for automatically recording program material off the satellite audio, video and data signals.

4. The system according to claim 1 further including a database storing event triggers for automatically synchronize playing back program material recorded off the satellite audio, video and data signals using a time base recorded from said satellite.

5. The system according to claim 1 further including a database containing satellite program guides for identifying a desired satellite to track and transceive information therefrom.

6. The system according to claim 1 further including a unit enabling the receipt of communication from a passenger for transmission to a ground station via a satellite.

7. The system according to claim 1 further including a unit responsive to a passenger making selections of content material for display.

8. In a system having an antenna for tracking and receiving intelligence bearing signals from satellites for distribution to a multiplicity of devices on an aircraft, a method for automatically switching between different satellites while the aircraft is in route, said method comprising:

a. retrieving navigational data from systems of said aircraft;

b. determining if a service region of said first satellite is in transition, and if so;

c. determining if satellite service overlaps with a second satellite, and if said second satellite signal is stronger, and if yes;

d. acquiring service from said second satellite by pointing said antenna to said second satellite;

e. configuring second intelligence signals received from said second satellite; and

,

f. displaying and distributing said configured second intelligence signals received from said second satellite to devices within said aircraft.

9. The method as in claim 8 wherein it is determined that said second satellite signal is not stronger, remaining locked onto said first satellite and repeating all the steps of claim 8.

10. The method as in claim 8 wherein it is determined that the service region of said first satellite is not in transition, further including the step of retrieving navigational data from systems of said aircraft.

11. The method as in claim 8 wherein it is determined that satellite service overlaps with a second satellite and said second satellite signal is stronger, further including the step of displaying a notification to said devices within said aircraft that new intelligence signals will soon be received.

12. The method as in claim 8 further including the step of determining, in response to navigational data of said aircraft, the right to transceive said intelligence bearing signals within various geographical regions by applying regulatory criteria from a database containing such information.

13. The method as in claim 8 further including storing in a database event triggers for automatically recording program material off the satellite audio, video and data signals.

14. The method as in claim 8 further including storing in a database event triggers for automatically synchronizing playing back program material recorded off the satellite audio, video and data signals using a time base recorded from said satellite.

16. The storage medium as in claim 15 wherein it is determined that said second satellite signal is not stronger, remaining locked onto said first satellite and repeating all the steps of claim 15.

17. The storage medium as in claim 15 wherein it is determined that the service region of said first satellite is not in transition, further including the step of retrieving navigational data from systems of said aircraft.

18. The storage medium as in claim 15 wherein it is determined that satellite service overlaps with a second satellite and said second satellite signal is stronger, further including the step of displaying a notification to said devices within said aircraft that new intelligence signals will soon be received.
