Method and system for determining delays between a primary site and diverse site in a satellite communication system
View Patent ↗A method and system for determining delays between a primary site and a diverse site in a satellite communication system includes uplinking signal from the primary site and the diverse site. A controller determines a switchover processing time, a communication time between the primary site and the diverse site and a gap time to establish a gap at the receiving device. The controller changes uplinking from the primary site to the diverse site in response to the switchover processing time, the communication time and the gap time.
1. A method comprising:
determining a switchover processing time;
determining a communication time between a primary site and a diverse site;
determining a gap time to establish a gap at a receiving device; and
changing uplinking from a primary site to a diverse site in response to the switchover processing time, the communication time and the gap time.
2. A method as recited in claim 1 wherein the switchover processing time corresponds to an upconverter switch-on time.
3. A method as recited in claim 1 wherein changing uplinking comprises opening an RF path in the primary site.
4. A method as recited in claim 3 wherein opening an RF path comprises disabling an upconverter.
5. A method as recited in claim 1 wherein changing uplinking comprises closing an RF path in the diverse site.
6. A method as recited in claim 5 wherein closing an RF path comprises enabling an upconverter.
7. A method as recited in claim 1 wherein changing uplinking comprises opening an RF path in the primary site and closing the RF path in a diverse site.
8. A method as recited in claim 7 wherein opening the RF path comprises disabling a first upconverter in the primary site and closing an RF path comprises enabling a second upconverter at the diverse site.
9. A method as recited in claim 7 wherein opening the RF path in the primary site and closing the RF path in the secondary site is controller at a primary site.
10. A system comprising:
a primary site selectively uplinking signals;
a diverse site selectively uplinking signals;
a communication line coupling the primary site and the diverse site; and
a controller determining a switchover processing time, determining a communication time between a primary site and a diverse site, determining a gap time to establish a gap at a receiving device, said controller changing uplinking from a primary site to a diverse site in response to the switchover processing time, the communication time and the gap time.
11. A system as recited in claim 10 wherein the controller is coupled to the primary site.
12. A system as recited in claim 10 wherein the switchover processing time corresponds to an upconverter switch-on time.
13. A system as recited in claim 10 wherein the controller changing uplinking comprises said controller controlling the opening an RF path in the primary site.
14. A system as recited in claim 13 wherein said controller opening an RF path comprises said controller disabling an upconverter.
15. A system as recited in claim 10 wherein said controller changing uplinking comprises said controller closing an RF path in the diverse site.
16. A system as recited in claim 10 wherein said controller closing an RF path comprises said controller enabling an upconverter.
17. A system as recited in claim 10 wherein said controller changing uplinking comprises said controller opening an RF path in the primary site and said controller closing the RF path in a diverse site.
18. A system as recited in claim 10 wherein said controller opening the RF path comprises said controller disabling an upconverter in the primary site and said controller closing an RF path comprises said controller enabling an upconverter.
