Magnetic satellite detumbling: The b-dot algorithm revisited

2015 American Control Conference (ACC), 2015
The first task a spacecraft attitude control system must perform after separation from the launcher is to detumble the spacecraft, i.e., to bring it to a final condition with a sufficiently small angular momentum. Magnetic control has been used for decades to fulfill this task, typically using the socalled b-dot control law (in all its variants ...

An Application of Eddy Current Effect on the Active Detumble of Uncontrolled Satellite With Tilt Air Gap

IEEE transactions on magnetics, 2019
The active removal of expired satellites on orbit is essential to ensure the safety of functional spacecrafts on orbit. The high tumbling rates of the uncontrolled satellites hinder the direct removal operation.

Robust Magnetic Attitude Control of Satellites

IEEE/ASME Transactions on Mechatronics, 2013
Magnetic torquers are frequently adopted as primary actuators for the attitude control of small satellites in low Earth orbit. Such actuators generate a magnetic dipole which, in turn, leads to control torques thanks to the interaction with the magnetic field of the Earth.

Magnetic satellites in mictomagnetic CuMn

Journal of Physics F: Metal Physics, 1983
The neutron scattering intensities about the 11/20 diffuse peak, in 15 and 40 at.% CuMn single crystals have been investigated. It is suggested that the maxima in the diffuse magnetic scattering intensity, which occurs at 1, 1+or- delta ', 0 type positions, is caused by an interaction with the conduction electrons.
