→Application in Satellite Control
== Application in Satellite Control ==
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 state with a sufficiently small angular momentum. Magnetic control has been used for decades to fulfill this task (in all its variants developed and flown through the years). <br \>
Not only for detumbling, the B-Dot law is used to damp the motion of the satellite in the case of very high angular rates.<ref>http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=7171005 </ref>
