Research on Sun-Oriented Spin-Stabilized Attitude Control of Micro/Nano Satellite Using Only Magnetic Control

Sun-oriented attitude control is one of the most important modes for micro/nano satellites, which directly affects on-orbit energy acquisition. Therefore, it great importance to use simplest sensors and actuators reliable algorithm achieve sun-oriented control. A spin-stabilized method satellites using only magnetic proposed in this paper, progress divided into four phases: initial damping phase, sun-aligned spin-up phase. The influence shadow zone orbit, offset installation sun sensor solar panel, limitation field view sensor, environmental disturbance torques are all considered method. performance evaluated by numerical simulations, simulation results show that applicable satellite equipped with a 3-axis magnetometer as three torquers installed orthogonally actuators. Earth-orbit geomagnetic can provide sufficient torque.
