本标准描述了软件定义无线电（SDR）的空间通信无线电系统（STRS）体系结构，这是NASA空间和地面无线电的开放体系结构。STRS提供了一个通用、一致的框架，将应用软件从无线电平台硬件中抽象出来，以降低在NASA任务中使用复杂的可重新配置和可重新编程无线电系统的成本和风险。美国国家航空航天局认可。奥西。

This Standard describes the Space Telecommunications Radio System (STRS) architecture for software-defined radios (SDRs), an open architecture for NASA space and ground radios. STRS provides a common, consistent framework to abstract the application software from the radio platform hardware to reduce the cost and risk of using complex reconfigurable and reprogrammable radio systems across NASA missions.
