Abstract
A system comprises a modulator, a time synchronization system, a satellite gateway computer, and a traffic gateway. The modulator is configured to transmit a first and a second carrier on a feeder uplink frequency to a beam-hopping-capable satellite according to a time schedule. The timing synchronization system is configured to synchronize a satellite gateway computer, the modulator, and the beam hopping capable satellite, based on the transmit time schedule and a propagation delay. The satellite gateway computer is programmed to determine transmit time schedule for the modulator, format and relay packets destined to the first and second downlink beam to the modulator to be transmitted on the first and second carrier during the first and second dwell time slot.
