Detailed Description
This class manages spacecraft momentum.
It computes the total spacecraft momentum based on the reaction wheel speeds and IMU rates. This module assumes you have momentum or reaction wheels. It then computes the total momentum and applies a gain to produce a momentum unloading torque demand. This demand is supplied to whatever actuators will do the unloading. No assumption of unloading device is made here.
