Feature
Adding the aerodynamic disturbance torque to the attitude model. Part 3.1 of #190
Desired Behavior / Functionality
The modelled spacecraft should have a torque acting on it due to the aerodynamic forces (lift and drag) resulting from its interaction with the higher atmosphere. The model to describe such forces is the one used in "Roto-Translational Spacecraft Formation Control Using Aerodynamic Forces", Ran S. et al. , JOURNAL OF GUIDANCE, CONTROL, AND DYNAMICS, 2017.
The function output shall be the aerodynamic torque vector calculated from the aerodynamic forces on each face of the satellite.
What Needs to Be Done
A location is already determined in the attitude model where this implementation should go. Hence, the aerodynamic disturbance model needs to be implemented as a function, and then the correct actor/simulation parameters should be implemented.
How Can It Be Tested
By creating a pytest test. It is possible to implement tests that verify that the aerodynamic torque values correspond to torques experienced by previously flown satellites in the same orbit. With the attitude model, it is possible to verify (in simple cases) that the aerodynamic-induced model attitude changes align with the expected change in attitude.
