Simulation of rigidly-linked nanosatellites [PDF]

, 2004
Rigidly linked nanosatellites are simulated as part of a PhD research on a new concept of space structure. Applications include a 1D interferometer in Earth and Lagrange orbits and a 3D Solar concentrator in Earth and Moon orbit.

Monitoring of Riverine Aquatic Vegetation Using Satellite PlanetScope Imagery: Feasibility, Limitations and Prospects

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Spectral interference induced by the water and the spatial resolution of many satellite images (≥ 10 m) limit the efficiency of remote sensing for monitoring riverine aquatic plant stands. In this study, the potential of using PlanetScope satellite images (3 m in spatial resolution, ~daily acquisition) for monitoring seasonal and interannual ...

Optimal Control of CubeSat Formations With Discrete On/Off Thrusters

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
The formation control of CubeSat‐class nanosatellites in low Earth orbit faces significant hurdles due to the discrete on/off nature and restricted switching frequency of their impulsive thrusters. A leader‐follower framework addresses these challenges by reformulating the control task as a constrained convex optimization problem that explicitly ...

Premature Reentry of the Binar CubeSats Due To Underestimation of Solar and Geomagnetic Activities and Its Implication for Importance of Medium‐ and Long‐Term Space Weather Forecasts

Space Weather, Volume 23, Issue 12, December 2025.
Abstract The rapid development of low‐Earth orbit (LEO) satellites brings increased attention to spacecraft collisions, space debris, orbital decay, and satellite reentry. Neutral density and associated drag force on the satellite orbits elevate space risks, significantly determined by space weather disturbances, particularly geomagnetic storms.

Design of a Scientific-Grade Multispectral Imager for Nanosatellites [PDF]

, 2023
Applications in agriculture, land-cover change, and vegetation phenology, to name a few, would benefit from more frequent high-quality remote sensing data. However, ”Landsat-class” satellites are too expensive for such applications. Therefore, there is a

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems

Advanced Optical Materials, Volume 13, Issue 33, November 25, 2025.
The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...
