The Smart Nanosatellite Attitude Propagator is an attitude propagator for
satellites that can be used to analyze the environmental torques affecting a
satellite and to design and analyze passive attitude stabilization techniques,
such as Passive Magnetic Stabilization, Gravity Gradient Stabilization and

The model implements:
- A simple two-body gravitational model for orbit propagation
- Gravity gradient torque
- Magnetic torque due to permanent magnets
- Magnetic hysteresis torque and damping
- Aerodynamic torque for spacecraft that are rotationally symmetric every 90 degrees.
