1. A system for gateway RF diversity using a configurable spot beam satellite comprising:
- a satellite;
a first gateway connected to a first VSAT population through the satellite by a first gateway spot beam and a first user spot beam set comprising at least one user spot beam;
a second gateway connected to a second VSAT population through the satellite by a second gateway spot beam and a second user spot beam set comprising at least one user spot beam;
a diversity gateway located outside of the first gateway spot beam for the first gateway; and
a diversity control function;
wherein the diversity control function is configured to command the satellite to connect the first user spot beam set for the first gateway to a diversity gateway spot beam when the first gateway experiences service interruption, andwherein the diversity control function is further configured to determine diversity priority metrics for the first gateway spot beam and a second gateway spot beam and command the satellite to connect at least one user spot beam set for the gateway whose corresponding gateway spot beam has the higher diversity priority metric to the diversity gateway spot beam when the first gateway and the second gateway both experience service interruptions.

15. A method for gateway RF diversity using a configurable spot beam satellite comprising:
-
detecting service interruption at a first gateway; determining that a diversity gateway is available; commanding a satellite to connect a first user spot beam set for the first gateway to a diversity gateway spot beam for the diversity gateway; determining a diversity priority metric for a first gateway spot beam for the first gateway and for a second gateway spot beam for a second gateway; and commanding the satellite to connect at least one user spot beam set for the gateway whose corresponding gateway spot beam has the higher diversity priority metric to the diversity gateway spot beam when the first gateway and the second gateway both experience service interruptions. - View Dependent Claims (16, 17, 18)

19. A method for gateway RF diversity using a configurable spot beam satellite comprising:
-
detecting service interruption at a first gateway; detecting service interruption at a second gateway; determining that a diversity gateway is available; determining a diversity priority metric for a first gateway spot beam for the first gateway and for a second gateway spot beam for the second gateway; and commanding a satellite to connect a first user spot beam set for the first gateway to a diversity gateway spot beam for the diversity gateway if the diversity priority metric for the first gateway spot beam is higher than the diversity priority metric for the second gateway spot beam or commanding the satellite to connect the second user spot beam set for the second gateway to the diversity gateway spot beam for the diversity gateway if the diversity priority metric for the first gateway spot beam is not higher than the diversity priority metric for the second gateway spot beam. - View Dependent Claims (20, 21, 22)

23. A system for gateway RF diversity using a configurable spot beam satellite comprising:
-
a satellite; a first gateway connected to a first VSAT population through the satellite by a first gateway spot beam and a first user spot beam set comprising at least one user spot beam; a diversity gateway located outside of the first gateway spot beam for the first gateway; a diversity control function; and a common L3 site connected via backhaul link to the first gateway and the diversity gateway, wherein the diversity control function is configured to command the satellite to connect the first user spot beam set for the first gateway to a diversity gateway spot beam when the first gateway experiences service interruption, wherein the common L3 site is configured to provide common Internet connectivity for the first gateway and the diversity gateway and allow VSAT connectivity to be switched between the gateways for RF diversity, while preserving established Internet routing for static IP subnet addresses associated with the VSATs, wherein the first gateway and the diversity gateway are connected both to the Internet and to the common L3 site and wherein traffic for VSATs with dynamic subnet addresses is exchanged directly between the Internet and gateway, and traffic for VSATs with static subnet addresses is exchanged by way of the common L3 site.
