Overview

This standard contains requirements to ensure the following: compatibility of frequency usage and modulation schemes between space agencies' spacecraft and Earth stations for the Space Operation, Space Research and Earth Exploration-Satellite services; compatibility between the spacecraft and the networks that they interact with, as far as possible; standardization of frequency usage and modulation schemes within the space projects; conformity of spacecraft and Earth station parameters to international radio regulatory provisions [Radio Regulations of the International Telecommunication Union (ITU)] and with national regulatory provisions (for example national frequency plans); selection of the appropriate parameters of spacecraft and Earth stations that are listed in advance of their use, thus enabling coordination with other interested parties; optimization of the frequency usage and modulation schemes within the above limitation. This standard defines the radio communication techniques used for the transfer of information between spacecraft and Earth stations in both directions, and for the tracking systems used for orbit determination. It includes the following: frequency allocation, assignment and use; requirements on transmitted signals concerning, for example, spectral occupation, RF power levels, protection of other radio services; definition of the permissible modulation methods and parameters; specification of the major technical requirements relevant for the interface between spacecraft and Earth stations; operational aspects, such as acquisition; cross-support. This standard is applicable to all spacecraft supported by Earth stations and to all controlled Earth stations operating in the Space Operation, Space Research and Earth Exploration-Satellite services as defined in the ITU Radio Regulations. Other space telecommunication services are not covered in this issue. All requirements in this standard are equally applicable to both the customer and the supplier with the exception of Subclauses 4.3.1 and 4.3.2 which are only applicable to the customer. Further provisions and guidance on the application of this standard can be found, respectively, in ECSS-E-ST-50 "Communications", and in the handbook ECSS-E-HB-50A "Communications guidelines". ECSS-E-ST-50 defines the principle characteristics of communication protocols and related services for all communication layers relevant for space communication (physical- to application-layer), and their basic relationship to each other. The handbook ECSS-E-HB-50 provides information on specific implementation characteristics of these protocols in order to support the choice of a certain communications profile for the specific requirements of a space mission. Users of the present standard are invited to consult these documents before taking decisions on the implementation of the present one. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00. This document (EN 16603-50-05:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document has been developed to specifically cover space systems and therefore has precedence over any European Standard since it covers the same scope but with a wider domain of applicability (for example aerospace).
