Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack
Systems Engineering, EarlyView.ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...
