STRS-AR-00002 (REV. 1.02.1), SPACE TELECOMMUNICATIONS RADIO (STRS) ARCHITECTURE STANDARD (MAR-2010)., This document describes the Space Telecommunications Radio System (STRS) Architecture Standard for software defined radios (SDRs), which is an open architecture for NASA space and ground radios. The STRS standard provides a common, consistent framework to develop, qualify, operate and maintain complex reconfigurable and reprogrammable radio systems. This architecture standard provides a detailed description and set of requirements to implement the architecture. The standard focuses on the key architecture components and subsystems by describing their functionality and interfaces for both the hardware and the software including waveform applications. A corresponding STRS Architecture Description document provides insight to the drivers and requirements that were considered to define the architecture and additional information on the architecture elements. The intended audience of the STRS Architecture Standard document is the software, firmware, and hardware developers of both the software defined radio platform and the waveform applications, who require the architecture specification details. By comparison, the STRS Architecture Description document is written at a higher level for the systems engineer, to understand the requirements, concepts, and approach to the STRS architecture. In the STRS Architecture Description document, three different examples are presented based upon the different platform profiles (e.g. small, medium, and large). These three possible realizations are not mandated, but serve to illustrate that the STRS Architecture Standard is suitable to provide physically realizable radio implementations and is flexible enough to meet the range of mission profiles.
