I’m simulating a reentry with different atmospheric models and I have seen that the reentry time with the SimpleExponentialAtmosphere is about 40 years and with the Harris Priester Model is about 2 years.
I have seen that the density values at each altitude for both models are very similar and I don’t know why this time difference is that big. Is this a normal behaviour, or am I missing something?
The configuration for the SimpleExponentialModel is:
atm = SimpleExponentialAtmosphere(earth, 0.0004, 42000.0, 7500.0) drag_force = DragForce(atm, isotropic_drag) propagator.addForceModel(drag_force)
The configuration for the Harris Priester is:
drag_force = DragForce(HarrisPriester(sun, earth), isotropic_drag) propagator.addForceModel(drag_force)
Many thanks in advance
