Purpose

The purpose of this Handbook is to present the rationale which underlays the requirements contained in NASA-STD-4009, Space Telecommunications Radio System (STRS) Architecture Standard, the companion document to this Handbook. Supporting examples and further descriptions for clarification of portions of NASA-STD-4009 are also provided. Answers prompted by questions from the Space Communications and Navigation (SCaN) Testbed partners, who created the first space implementation of STRS, are also included. As the Standard evolves, minor corrections and updates to obsolete information will be added to the Handbook. The Handbook is aimed at helping readers and implementers of NASA-STD-4009 understand the Standard.

NASA-STD-4009 provides an STRS overview, background, and detailed descriptions that might be useful to the reader not familiar with the STRS architecture.

Applicability

This Handbook is applicable to providing the rationale as well as additional information to NASA-STD-4009, which is a standard for reconfigurable communication transceiver developments among NASA missions.
