<br>
</div>
<div align="left">This scenario uses Eulerfs rotational equations of motion
to simulate the<br>
attitude dynamics of a rigid spacecraft with optional body-fixed, constant
<br>
torques. Eulerfs rotational equations of motion is found in most of the
<br>
textbooks on spacecraft dynamics <br>
<br>
<b><u>Inputs<br>
</u></b><br>
<b>Ixx</b>, <b>Iyy, Izz</b> Principal moments of inertia<br>
<b>M1,M2,M3</b> External torque acting in the b1
direction<br>
<br>
<b><u>Initial Condition</u></b><br>
<br>
<b>w1</b>, <b>w2, w3</b>: Spacecraft angular velocities
<br>
<b>q1, q2, q3, q4</b>: Quaternions<br>
