  • Patent number: 11831346
    Abstract: Combinations of antenna types, which may include parabolic reflectors, electronically scanned arrays (ESAs), lens antennas and other directional antenna types enable a satellite ground terminal that is adaptable for use in multiple frequency bands such as C, Q, V, Ku, X and Ka bands, with satellites in various orbital configuration such as LEO, MEO, other non-GEO, and GEO, and in various user scenarios such as fixed, At the Quick Halt (ATQH), or On-the-Move (OTM). The VSAT or MVSAT of the invention does not require alteration or modification to support these multiple uses cases. As a result of this interoperability there are savings in unit cost and logistics. The system and method of the invention allow rapid reconfiguration of the ground segment of a satellite communication system to overcome loss of space segment assets, by enabling the inventive ground terminal to quickly transition to communicate with alternative satellites.
