A radio-frequency (RF) redundancy method includes configuring a plurality of RF gateways of a satellite communication system into a redundancy group, At least one RF gateway is configured to operate in an active state to handle data transmissions and at least one RF gateway is configured to operate in an idle state as a backup RF gateway. The method includes detecting a fault condition associated with an RF gateway operating in the active state, and performing a switchover process that reassigns operational roles among RF gateways in the redundancy group by configuring a previously idle RF gateway to operate in the active state and configuring the RF gateway associated with the fault condition to operate in the idle state.
