    • This disclosure provides a communications system using a span-loaded flying wing, traveling at relatively slow speeds, that can remain airborne for long periods of time. The communications system uses the airplane as a long term high altitude platform that can serve at least one of a number of potential functions. One function is to link to a ground station using radio wave signals and a satellite using optical signals. Another function is to serve as a relay station between ground communication nodes and individual end-users. Because the aircraft can tightly hold a station, the end-user's antennas do not need to be continuously adjustable. For such a system, a large number of aircraft can be used, with the end-user antennas being configured for a narrow beamwidth so as to allow frequency reuse for different communication links.
    • 本公开提供了一种使用跨越负载的飞翼,以相对较慢的速度行进的通信系统,其可以长时间保持空中。 通信系统使用飞机作为可以服务于多个潜在功能中的至少一个的长期高空平台。 一个功能是使用无线电波信号和使用光信号的卫星连接到地面站。 另一个功能是作为地面通信节点和个别最终用户之间的中继站。 因为飞机可以紧紧地固定一个电台,所以终端用户的天线不需要连续调节。 对于这样的系统,可以使用大量飞行器,其中最终用户天线被配置为具有窄的波束宽度,以允许不同通信链路的频率重用。
