射频和光通信概念终端设计；尺寸、重量和功率要求；并对三个具有代表性的 1 Gbps 链路的开发成本进行了比较。基于 32 GHz 射频、60 GHz 射频、AlGaAs 光学和 InGaAsP/EDFA 光学技术的 LEO 到 GEO、LEO 到 LEO 和 LEO 到地面终端的设计假定采用 2000 年技术。光学技术在 1 Gbps 数据速率下的天线尺寸、终端重量和经常性成本方面表现出优势。
Rf and optical communication conceptual terminal designs; size, weight, and power requirements; and development costs are compared for three representative 1-Gbps links. Year 2000 technology is assumed for the designs of LEO-to-GEO, LEO-to-LEO, and LEO-to- Ground terminals based on 32-GHz rf, 60-GHz rf, AlGaAs optical, and InGaAsP/EDFA optical technologies. The optical technologies exhibit advantages in the areas of antenna size, terminal weight, and recurring cost at the 1-Gbps data rate.
