This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2005,

39、 and conflicting national standards shall be withdrawn at the latest by February 2005. It is based on a previous version 1)originally prepared by the ECSS Working Group for Ground Systems and Operations, reviewed by the ECSS Engineering Panel and approved by the ECSS Steering Board. The European Coo

40、peration for Space Standardization (ECSS) is a cooperative effort of the European Space Agency, National Space Agencies and European industry associations for the purpose of developing and maintaining common standards. This European Standard is one of the series of space standards intended to be app

41、lied together for the management, engineering and product assurance in space projects and applications. Requirements in this European Standard are defined in terms of what shall be accomplished, rather than in terms of how to organize and perform the necessary work. This allows existing organization

42、al structures and methods to be applied where they are effective, and for the structures and methods to evolve as necessary without rewriting the standards. The formulation of this European Standard takes into account the existing EN ISO 9000 family of documents. According to the CEN/CENELEC Interna

43、l Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherla

44、nds, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. 1)ECSS-E-70-41 EN 14776:2004 (E) 8 Introduction ECSS-E-50 and the CCSDS recommendations for packet telemetry and telecommand address the end-to-end transport of telemetry and telecommand data between us

45、er applications on the ground and application processes on-board the satellite, and the intermediate transfer of these data through the different elements of the ground and space segments. This packet utilization standard (PUS) complements these standards by defining the application-level interface

46、between ground and space, in order to satisfy the requirements of electrical integration and testing and flight operations. EN 14776:2004 (E) 9 1 Scope This document addresses the utilization of telecommand packets and telemetry source packets for the purposes of remote monitoring and control of sub

47、systems and payloads. This document does not address mission-specific payload data packets, but the rules contained herein can be extended to suit the requirements of any mission. This document does not address audio and video data as they are not contained within either telecommand or telemetry sou

48、rce packets. This document is structured as follows. Firstly a set of operational concepts is identified, covering all the fundamental requirements for spacecraft monitoring and control during satellite integration, testing and flight operations. A set of services that satisfy these operational conc

49、epts is then defined. The detailed specification of these services includes the structure and contents of the associated service requests (telecommand packets) and service reports (telemetry source packets). This document is applicable to any mission, no matter what its domain of application, orbit or ground station coverage characteristics. However, it is not the intention that the PUS i
