Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack
Systems Engineering, Volume 29, Issue 6, Page 1152-1170, November 2026.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 ...

The Multifractal Structure of Small-Scale Artificial Ionospheric Turbulence
Open Astronomy, 2013 We present the results of investigation of a multifractal structure of the artificial ionospheric turbulence when the midlatitude ionosphere is affected by high-power radio waves.

Earth and Space Science, Volume 13, Issue 11, November 2026.Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.

The solar-cycle variation of M(3000)F2 and its correlation with that of f0F2
Annals of Geophysics, 1998 Using hourly monthly-median measured values from nine long-standing ionospheric sounding stations with data sets extending over several decades, best-fit empirical relationships are established for M (3000)F2 with different solar and ionospheric indices ...

Sound Channel in the Ionosphere
Journal of geomagnetism and geoelectricity, 1961 The distribution of the sound velocity is obtained by the distribution of the absolute temperature and wind. When the direction of the sound is toward west at the middle latitude, the minimum velocities in summer and winter are estimated to be 210m/s at 70km in height and 280m/s at an altitude of about 90km respectively.

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence
Earth and Space Science, Volume 13, Issue 11, November 2026.Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...
