Issue 6 vii January 1987 CCSDS REPORT CONCERNING TELECOMMAND: SUMMARY OF CONCEPT AND SERVICE 1 DOCUMENT PURPOSE AND ORGANIZATION 1 . 1 PURPOSE This report is a high level technical summary describing architectural concepts for space mission telecommand systems. These concepts, and their associated telecommanding services, have been developed by the participating Agencies of the international Consultative Committee for Space Data Systems (CCSDS). The operating principles and procedures for the CCSDS are defined in Reference [1]. This report has been prepared to serve two major purposes: (1) To provide an overview that will introduce a new reader to the system concepts upon which the detailed CCSDS Telecommand Recommendations (References [2], [3], [4], and [5]) are based. (2) To summarize the technical content of the three main architectural Recommendations (References [2], [3], and [4]), and to describe their context within the framework of a layered architecture for space mission telecommanding. This document is a CCSDS report that is intended for informational purposes, and as such it is not a part of the formal collection of CCSDS Telecommand Recommendations. 1 . 2 ORGANIZATION This report contains two major sections, supported by four Annexes: (1) Section 2 presents an overview of the CCSDS Telecommand (TC) System and its associated concepts. This section describes the application of architectural layering techniques to achieve transparent and reliable commanding of scientific instruments or engineering subsystems aboard remote space vehicles. (2) Section 3 presents a summary of the service concepts that lie behind the three main CCSDS telecommand Recommendations. The overall service framework developed in the prior section is used to discuss the services and functions within each layer. (3) Annex A contains a Glossary in order to familiarize the reader with the terminology used throughout the discussion of the CCSDS Telecommand System. (4) Annex B contains a guideline for generating the Telecommand Transfer Frame error control polynomial which is specified in Reference [3]. Issue 6 Page 1-1 January 1987 CCSDS REPORT CONCE...
