绳系太阳能动力卫星（Tethered Solar Power Satellite，SPS）是一种新型的太阳能动力卫星，它由一个具有发电/输电功能的大型太阳能电池板和一个总线系统组成，通过多根导线连接。发电/输电面板由大量完全等效的功率模块组成。在每个模块的表面处由太阳能电池产生的电功率在同一模块中被转换成微波功率。由于模块由使用无线LAN的总线系统控制，因此模块之间不需要有线信号/电源接口。微波发射天线指向地面的姿态由重力梯度力保持。系留面板由彼此松散连接的单独系留子面板组成。该配置使得能够实现其中SPS的功能随着构造的进行而增长的演进构造。系留子面板的缩比模型可用于SPS在不久的将来的第一步演示实验。
Tethered solar power satellite (Tethered-SPS) consisting of a large panel with a capability of power generation/transmission and a bus system which are connected by multi-wires is proposed as an innovative solar power satellite (SPS). The power generation/transmission panel is composed of a huge number of perfectly equivalent power modules. The electric power generated by the solar cells at the surface of each module is converted to the microwave power in the same module. Since the modules are controlled by the bus system using wireless LAN, no wired signal/power interfaces are required between the modules. The attitude in which the microwave transmission antenna is directed to the ground is maintained by the gravity gradient force. The tethered panel is composed of individual tethered subpanels which are loosely connected to each other. This configuration enables an evolutional construction in which the function of the SPS grows as the construction proceeds. A scale model of the tethered subpanel can be used for the first step demonstration experiment of the SPS in the near future.
