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.

On the possibility of determining the parameters of the ionosphere when removing a nanosatellite from orbit using an uninsulated conductive tether

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
Currently, one of the ways to quickly remove spent nanosatellites from orbit is the use of non-insulated conductive tether, during the movement of which an electrodynamic braking force arises in the Earth's magnetic field, transferring the nanosatellite ...
