Abstract
A satellite communication system comprises a satellite configured to provide a plurality of spot beams adapted for communication using time domain beam hopping to switch throughput among spot beams of the plurality of spot beams. The plurality of spot beams includes a first spot beam that illuminates and communicates with a first gateway and a first set of subscriber terminals. The satellite is configured to implement a beam hopping plan that during a hopping period provides throughput to the first spot beam for an aggregated time duration based on bandwidth assignments to the first gateway and the first set of subscriber terminals.

A method for operating a satellite, comprising:
- providing a plurality of spot beams from a satellite, the plurality of spot beams includes a first spot beam configured to illuminate a first gateway and multiple subscriber terminals;
- and
- performing time domain beam hopping for the plurality of spot beams including implementing a beam hopping plan that during a hopping period provides throughput to the first spot beam for an aggregated time duration based on bandwidth assignments of the first gateway and the multiple subscriber terminals.
A satellite communication system, comprising:
- a satellite configured to provide a plurality of spot beams adapted for communication using time domain beam hopping to switch throughput among spot beams of the plurality of spot beams, the plurality of spot beams includes a first spot beam that illuminates and communicates with a first gateway and a first set of subscriber terminals, the satellite is configured to implement a beam hopping plan that during a hopping period provides throughput to the first spot beam for an aggregated time duration based on bandwidth assignments to the first gateway and the first set of subscriber terminals.
A satellite communication system, comprising:
- a satellite configured to provide a plurality of spot beams divided into hopping groups such that the first satellite is configured perform time domain beam hopping to switch throughput among spot beams within each hopping group, the hopping groups include a first hopping group, the plurality of spot beams includes a first spot beam and a second spot beam. the first spot beam configured to communicate with a first gateway, the second spot beam configured to communicate with a second gateway, the first satellite includes a spectrum routing network that is configured to selectively connect the first hopping group to the first gateway at a first set of time periods and selectively connect the first hopping group to the second gateway at a second set of time periods different than the first time periods, the satellite provides throughput to the first spot beam for an aggregated time duration based on bandwidth assignments to the first gateway and a first set of subscriber terminals.
