L.5 Summary
Vipersat provides a dynamic mesh for remote-to-remote communication through its use of a
unique equipment topology and switching engine. It requires only a single transmitted SCPC
carrier from each remote, as opposed to having multiple carriers at each site. Corresponding
remote sites need available CDD-880 Multi-Receiver Router Expansion Units to receive the mesh
transmission; this establishes a true dynamic SCPC circuit between remotes.
Hardware costs are also significantly lower due to the ability to deploy the CDD-880s at both the
hub location and the remote sites. ACM maintains link connectivity by “down revving” the
ModCods while maintaining a constant symbol rate and power level.
