Angular momentum management in small spacecraft is important to maintain power, heat balance and communication environment. As a practical method, thruster is difficult to install because the smaller the spacecraft, the greater the influence of deviation from the torque axis during fuel injection. In this paper, we propose a method of angular momentum management using magnetic torque caused by an interplanetary magnetic field (IMF). Since the IMF fluctuates stochastically, it is unknown whether it can be used for angular momentum management. To indicate this, this report focuses on the frequency characteristics of the IMF and analyzes the noise component at first. Next, this report investigates the amount of angular momentum change caused by white and brownian noises then shows the possibility of angular momentum management. Numerical simulation shows angular momentum management using 1-axis MTQ and RWs considering IMF distribution.
