Space engineering - Electromagnetic compatibility

EMC policy and general system requirements are specified in ECSS-E-ST-20. This ECSS-E-ST-20-07 Standard addresses detailed system requirements (Clause 4), general test conditions, verification requirements at system level, and test methods at subsystem and equipment level (Clause 5) as well as informative limits (Annex A). Associated to this standard is ECSS-E-ST-20-06 “Spacecraft charging”, which addresses charging control and risks arising from environmental and vehicle-induced spacecraft charging when ECSS-E-ST-20-07 addresses electromagnetic effects of electrostatic discharges. Annexes A to C of ECSS-E-ST-20 document EMC activities related to ECSS-E-ST-20-07: the EMC Control Plan (Annex A) defines the approach, methods, procedures, resources, and organization, the Electromagnetic Effects Verification Plan (Annex B) defines and specifies the verification processes, analyses and tests, and the Electromagnetic Effects Verification Report (Annex C) document verification results. The EMEVP and the EMEVR are the vehicles for tailoring this standard. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Vesoljska tehnika - Elektromagnetna združljivost

Politika glede elektromagnetne združljivosti in splošne sistemske zahteve so opredeljene v standardu ECSS-E-ST-20. Ta standard ECSS-E-ST-20-07 obravnava podrobne sistemske zahteve (točka 4), splošne preskusne pogoje, pogoje glede preverjanja na sistemski ravni in preskusne metode na ravni podsistemov in opreme (točka 5) ter tudi informativne omejitve (dodatek A). S tem standardom je povezan standard ECSS-E-ST-20-06 o napajanju vesoljskih plovil, ki obravnava nadzor nad polnjenjem in tveganja, ki izhajajo iz okoljskega napajanja vesoljskih plovil ter napajanja, ki ga sproži vozilo, medtem ko standard ECSS-E-ST-20-07 obravnava elektromagnetne učinke elektrostatičnih praznitev. Dodatki A do C standarda ECSS-E-ST-20 beležijo dejavnosti v zvezi z elektromagnetno združljivostjo, povezane s standardom ECSS-E-ST-20-07: načrt obvladovanja elektromagnetne združljivosti (dodatek A) določa pristop, metode, postopke, vire in organizacijo, načrt za preverjanje elektromagnetnih učinkov (dodatek B) določa in opredeljuje procese, analize in preskuse v zvezi s preverjanjem, poročilo o preverjanju elektromagnetnih učinkov (dodatek C) pa beleži rezultate preverjanja. Načrt za preverjanje elektromagnetnih učinkov in poročilo o preverjanju elektromagnetnih učinkov služita za prilagajanje tega standarda. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

This standard (EN 16603-20-07:2014) originates from ECSS-E-ST-20-07C Rev. 1. 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 January 2015, and conflicting national standards shall be withdrawn at the latest by January 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.” SIST EN 16603-20-07:2014



EN 16603-20-07:2014 (E) 7 Introduction Electromagnetic compatibility (EMC) of a space system or equipment is the ability to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment. The space system is designed to be compatible with its external natural, induced, or man-made electromagnetic environment. Natural components are lightning for launchers, the terrestrial magnetic field for space vehicles. Spacecraft charging is defined as voltage building-up of a space vehicle or spacecraft units when immerged in plasma. Electrostatic discharges result from spacecraft charging with possible detrimental effects. External man-made interference, intentional or not, are caused by radar or telecommunication beams during ground operations and the launching sequence. Intersystem EMC also applies between the launcher and its payload or between space vehicles. Intrasystem EMC is defined between all electrical, electronic, electromagnetic, and electromechanical equipment within the space vehicle and by the presence of its self-induced electromagnetic environment. It comprises the intentional radiated electromagnetic fields and parasitic emission from on-board equipment. Both conducted and radiated emissions are concerned. An electromagnetic interference safety margin is defined at system critical points by comparison of noise level and susceptibility at these points. SIST EN 16603-20-07:2014



EN 16603-20-07:2014 (E) 8 1 Scope EMC policy and general system requirements are specified in ECSS-E-ST-20. This ECSS-E-ST-20-07 Standard addresses detailed system requirements (Clause 4), general test conditions, verification requirements at system level, and test methods at subsystem and equipment level (Clause 5) as well as informative limits (Annex A). Associated to this standard is ECSS-E-ST-20-06 “Spacecraft charging”, which addresses charging control and risks arising from environmental and vehicle-induced spacecraft charging when ECSS-E-ST-20-07 addresses electromagnetic effects of electrostatic discharges. Annexes A to C of ECSS-E-ST-20 document EMC activities related to ECSS-E-ST-20-07: the EMC Control Plan (Annex A) defines the approach, methods, procedures, resources, and organization, the Electromagnetic Effects Verification Plan (Annex B) defines and specifies the verification processes, analyses and tests, and the Electromagnetic Effects Verification Report (Annex C) document verification results. The EMEVP and the EMEVR are the vehicles for tailoring this standard. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
