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 stabilziation techniques,
such as Passive Magnetic Stabilization, Gravity Gradient Stabilziation and
Aerodynamic stabilization.

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 torue for spacecraft that are rotationally symmetric every 90 degrees.

For more information on the implementation and capabilities of the model, see:
