    • An emergency satellite communications system that provides remote sites with assured access. The network is provisioned, configured, and managed such that the remote units are always online, but not used to an extent that would prevent remote units from communicating via the network upon demand. The network may include geographic hub diversity to protect against hub failure. Proactive monitoring of the components comprising the network is used to mitigate or prevent network congestion, such as by load balancing. An overflow link may be provided, allowing for remote sites to be assigned from a first link to the overflow link to mitigate or prevent congestion on the first link, and/or allow for additional bandwidth to be allocated to one or more remote sites that remain on the first link. A satellite communication network may comprise a satellite and a network management system operative in controlling and managing a plurality of first and second terminals. A first earth station may be communicatively coupled to one or more terrestrial communications networks, where the first earth station provides a first communication link via the satellite for bidirectional communication between the first earth station and the plurality of first terminals assigned to the first earth station by the network management system. A second earth station may be geographically diverse from the first earth station and is communicatively coupled to at least one terrestrial communications network. The second earth station may provide a second communication link via the satellite for bidirectional communication between the second earth station and the plurality of second terminals assigned to the second earth station by the network management system.
    • 紧急卫星通信系统,为远程站点提供有保证的访问。 网络被配置,配置和管理,使得远程单元始终处于在线状态,但不会被使用,从而防止远程单元通过网络进行通信。 网络可以包括地理集线器分集以防止集线器故障。 包括网络的组件的主动监视用于减轻或防止网络拥塞,例如通过负载平衡。 可以提供溢出链路,允许将远程站点从第一链路分配给溢出链路以减轻或防止第一链路上的拥塞,和/或允许将额外的带宽分配给保留的一个或多个远程站点 在第一个链接。 卫星通信网络可以包括卫星和网络管理系统,其操作以控制和管理多个第一和第二终端。 第一地球站可以通信地耦合到一个或多个地面通信网络,其中第一地球站经由卫星提供第一通信链路,用于通过分配给第一地球站的第一地球站与多个第一终端之间的双向通信,由第 网络管理系统。 第二地球站可以在地理上与第一地球站不同,并且通信地耦合到至少一个地面通信网络。 第二地球站可以经由卫星提供第二通信链路,用于通过网络管理系统在第二地球站与分配给第二地球站的多个第二终端之间进行双向通信。
