Multi-Carrier Satellite Network Supporting Heterogeneous Terminals

In a satellite communication system, comprising a hub and a plurality of heterogeneous terminals, the hub may split a bandwidth segment designated for a forward channel into at least two carriers, wherein some of the terminals may listen on a first carrier and some other terminals may listen on the at least second carrier. In this system, the hub may re-arrange the split of the bandwidth segment between the various carriers populating it in real-time or substantially in real-time, while the carriers are actively transmitted, and without causing loss of service and/or loss of data to terminals listening on those carriers. The terminals may be configured to track the carriers as they are re-arranged and to maintain seamless service to the end user throughout the re-arrangement process.
