Space engineering - Assessment of space worst case charging handbook

Common engineering practices involve the assessment, through computer simulation (with software like NASCAP [RD.4] or SPIS [RD.5]), of the levels of absolute and differential potentials reached by space systems in flight. This is usually made mandatory by customers and by standards for the orbits most at risk such as GEO or MEO and long transfers to GEO by, for example, electric propulsion.
The ECSS-E-ST-20-06 standard requires the assessment of spacecraft charging but it is not appropriate in a standard to explain how such an assessment is performed. It is the role of this document ECSS-E-HB-20-06, to explain in more detail important aspects of the charging process and to give guidance on how to carry out charging assessment by computer simulation.
The ECSS-E-ST-10-04 standard specifies many aspects of the space environment, including the plasma and radiation characteristics corresponding to worst cases for surface and internal charging. In this document the use of these environment descriptions in worst case simulations is described.
The emphasis in this document is on high level charging in natural environments. One aspect that is currently not addressed is the use of active sources e.g. for electric propulsion or spacecraft potential control. The tools to address this are still being developed and this area can be addressed in a later edition.

Vesoljski inženiring - Ocena priročnika za polnjenje v najslabšem primeru v vesolju

Običajne inženirske prakse vključujejo oceno ravni absolutnih in diferencialnih potencialov, ki jih dosegajo vesoljski sistemi med letom. Za oceno se uporabi računalniško simulacijo (s programsko opremo, kot sta NASCAP [RD.4] ali SPIS [RD.5]). To običajno zahtevajo stranke in standardi za orbite z največjim tveganjem, kot sta GEO ali MEO, in dolgi prenosi v GEO, na primer z električnim pogonom.
Standard ECSS-E-ST-20-06 zahteva oceno polnjenja vesoljskih plovil, vendar v njem ni pojasnjeno, kako se taka ocena izvaja. Naloga dokumenta ECSS-E-HB-20-06 je namreč, da podrobneje opiše pomembne vidike postopka polnjenja in poda napotke, kako izvesti oceno polnjenja z računalniško simulacijo.
Standard ECSS-E-ST-10-04 določa številne vidike vesoljskega okolja, vključno s plazemskimi in sevalnimi lastnostmi, ki ustrezajo najslabšim primerom površinskega in notranjega polnjenja. V tem dokumentu je opisana uporaba teh opisov okolja v simulacijah najslabšega primera.
Poudarek je na visoki ravni polnjenja v naravnem okolju. Eden od vidikov, ki trenutno ni obravnavan, je uporaba aktivnih virov, npr. za električni pogon ali nadzor potenciala vesoljskega plovila. Orodja za obravnavo tega se še razvijajo in to področje bo mogoče obravnavati v poznejši izdaji.
