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 ...

Q-GERT survivability assessment of LEO satellite constellation

Wireless Networks, 2020
Due to the complexity of space environment and the difficulty of satellite maintenance in outer space, survivability has become one of the most important problems of LEO satellite constellation. Network survivability is the ability of a system to complete communication missions in case of encountering accidents, failures or attacks.
