Solar pressure model in 'SphericalSpacecraft.java'
I do not fully understand the way solar pressure force is computed in
the frame of 'SphericalSpacecraft.java'. It appears that
'radiationPressureAcceleration' is computed as
kP = crossSection * (1 + 4 * (1.0 - absorptionCoeff) * (1.0 -
specularReflectionCoeff) / 9.0);
If I refer to the document available on your project webpage
(https://www.orekit.org/forge/documents/33) equation (3.18), I wonder if
the correct formula would not rather be:
kP = crossSection * (1 + 4 * (1.0 - absorptionCoeff -
specularReflectionCoeff) / 9.0);
Could you confirm or disconfirm ?
One other point : Is partial illumination taken into account in the frame of SphericalSpacecraft ?
Thanks a lot for your answers !
