Electric Cleanliness Algorithm based on Multi-Unit Interaction and Reallocation

Abstract

Authors prior to this work proposed a methodology providing electric or magnetic cleanliness on spacecraft implementation by reordering equipment units. More precisely, since the mission's scientific goal relies on the payload's high sensitivity and accuracy for capturing the space environment, field minimization in measuring instrument location is imperative. Electromagnetic cleanliness is a constant open issue, since the mission target relies on clean measurements without including spacecraft self-emissions. A lot of science missions of ESA, NASA, or JAXA select usually a set of a couple of basic units as standard payload, i.e. batteries, Radio Frequency switches, Command units or Data Handling Management units, S-Band Transceivers, Power Distribution Units, etc. The later is usually measured and electromagnetically characterized by employing the on-ground facilities providing equivalent radiating models. This work provides a supplementary module to the formerly created framework for an entire unit positioning approach, taking into account the unit’s test-level data, for suitable allocation of the space vessel’s equipment toward electric cleanliness purposes taking into consideration the unit’s induced behavior.
