Abstract

A method of configuring an express mesh satellite network includes monitoring a plurality of satellites in a constellation, wherein each of the plurality of satellites includes a plurality of coherent optical modems; determining a topology of the constellation based on (1) ground traffic sources and sinks and (2) locations of any of the plurality of satellites; and causing the any of the plurality of satellites and their corresponding plurality of coherent optical modems to perform one or more of a relay function and a ground link, with corresponding coherent optical modems of the plurality of coherent optical, and based on the topology.

Claims (30)

1 . A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to perform steps of:

monitoring a plurality of satellites in a constellation, wherein each of the plurality of satellites includes a plurality of coherent optical modems;

determining a topology of the constellation based on (1) ground traffic sources and sinks and (2) locations of any of the plurality of satellites, wherein the topology includes express links connecting satellites by coherent optical modems configured to dynamically select wavelengths for each express link based on line-of-sight connectivity and traffic demands, the selected wavelengths being assigned between satellites based on the traffic demands; and

causing the any of the plurality of satellites and their corresponding plurality of coherent optical modems to perform one or more of a relay function and a ground link, with corresponding coherent optical modems of the plurality of coherent optical, and based on the topology.

2 . The non-transitory computer-readable medium of claim 1 , wherein the steps further include

causing some or all of the plurality of coherent optical modems in a corresponding satellite of the plurality of satellites to power down or reduce power based on the topology.

3 . The non-transitory computer-readable medium of claim 1 , wherein the steps further include

causing configuration of the plurality of coherent optical modems in the any of the plurality of satellites based on the topology.

4 . The non-transitory computer-readable medium of claim 3 , wherein the configuration includes a modulation format to accommodate required direct connection distance to another satellite with required bandwidth.

5 . The non-transitory computer-readable medium of claim 1 , wherein the topology includes a limit to a number of hops to reach any satellite over a geographic area.

6 . The non-transitory computer-readable medium of claim 1 , wherein the plurality of satellites are configured to move in the topology.

7 . The non-transitory computer-readable medium of claim 6 , wherein the topology includes one or more express links whereby adjacent satellites are skipped.

8 . The non-transitory computer-readable medium of claim 6 , wherein a given satellite is configured to change in the topology based on corresponding movement.

9 . The non-transitory computer-readable medium of claim 1 , wherein the plurality of satellites are fixed in the topology when in an affinity area.

10 . The non-transitory computer-readable medium of claim 1 , wherein the topology includes a mesh.

11 . A method of configuring an express mesh satellite network comprising step of:

monitoring a plurality of satellites in a constellation, wherein each of the plurality of satellites includes a plurality of coherent optical modems;

determining a topology of the constellation based on (1) ground traffic sources and sinks and (2) locations of any of the plurality of satellites, wherein the topology includes express links connecting satellites by coherent optical modems configured to dynamically select wavelengths for each express link based on line-of-sight connectivity and traffic demands, the selected wavelengths being assigned between satellites based on the traffic demands; and

causing the any of the plurality of satellites and their corresponding plurality of coherent optical modems to perform one or more of a relay function and a ground link, with corresponding coherent optical modems of the plurality of coherent optical, and based on the topology.

12 . The method of claim 11 , wherein the steps further include

causing some or all of the plurality of coherent optical modems in a corresponding satellite of the plurality of satellites to power down or reduce power based on the topology.

13 . The method of claim 11 , wherein the steps further include

causing configuration of the plurality of coherent optical modems in the any of the plurality of satellites based on the topology.

14 . The method of claim 13 , wherein the configuration includes a modulation format to accommodate required direct connection distance to another satellite with required bandwidth.

15 . The method of claim 11 , wherein the topology includes a limit to a number of hops to reach any satellite over a geographic area.

16 . The method of claim 11 , wherein the plurality of satellites are configured to move in the topology.

17 . The method of claim 16 , wherein the topology includes one or more express links whereby adjacent satellites are skipped.

18 . The method of claim 16 , wherein a given satellite is configured to change in the topology based on corresponding movement.

19 . The method of claim 11 , wherein the plurality of satellites are fixed in the topology when in an affinity area.

20 . The method of claim 11 , wherein the topology includes a mesh.
