A patent application (Publication Number: US20240015526A1) describes a satellite communication network topology featuring a single electronically steered flat-panel antenna capable of generating multiple beams. The network includes two virtualized hubs and satellites, with network control managing satellite links and routing traffic between the antenna and satellites. A Coordinated Multi-point (CoMP) coordinator coordinates traffic routing, while a user terminal with soft modems and the antenna schedules data transmission windows. The network control, including a MWAN edge router and SDWAN controller, routes traffic based on business rules, with load balancing and failover capabilities.

The patent application further details a method for controlling communication in a satellite network with multiple constellations and a terminal featuring a single electronically steered flat-panel antenna. The method involves determining network availability, managing satellite links between the antenna and satellites, and using beam splitting to maintain communication links simultaneously. Fast switching allows the antenna to repoint to different satellites when data is available, with beam splitting and fast switching performed during receive and transmit operations. Additionally, the method includes routing traffic through different hubs in response to disruption conditions, such as line-of-sight disruptions, and weighting beams based on network functions to optimize communication efficiency. The innovative approach outlined in the patent application aims to enhance satellite communication network performance and reliability through advanced routing and control mechanisms.
