摘要：
Method and system for addressing line of sight (LOS) blockage in satellite communication networks are provided herein. The method may include the following stages: obtaining forecast input parameters; forecasting at least one future LOS blockage in two or more communication links established between at least one communication satellite and at least one platform-mounted communication system having at least one antenna, based on the forecast input parameters; and addressing the future LOS blockage by applying at least one of: rerouting the communication links between the at least one platform-mounted communication system and at least one of the communication satellite; changing a power level of at least one of the communication links; changing at least one of: spreading, modulation and coding of at least one of the communication links; changing mobility parameters of the platform-mounted communication system.
摘要（中）：
本文提供了在卫星通信网络中寻址视线（LOS）阻塞的方法和系统。 该方法可以包括以下阶段：获取预测输入参数; 基于所述预测输入参数，在至少一个通信卫星和至少一个具有至少一个天线的平台安装的通信系统之间建立的两个或更多个通信链路中预测至少一个未来的LOS阻塞; 以及通过应用以下至少一个来解决未来的LOS阻塞：重新路由至少一个平台安装的通信系统与通信卫星中的至少一个之间的通信链路; 改变至少一个通信链路的功率电平; 改变至少一个通信链路的扩展，调制和编码; 改变平台安装通信系统的移动性参数。
