public SolarRadiationWrench(PVCoordinatesProvider sunBody, GeometricBodyShape shape, RadiationWrenchSensitive spacecraftModel)
When this constructor is used, the reference values are:
sunBody
- Sun modelshape
- earth model (for umbra/penumbra computation)spacecraftModel
- the object physical and geometrical informationpublic SolarRadiationWrench(double distance, double pressure, double sunRadius, PVCoordinatesProvider sunBody, GeometricBodyShape shape, RadiationWrenchSensitive spacecraftModel)
Note that reference solar radiation pressure pRef
in N/m2 is linked to solar flux SF in
W/m2 using formula pRef = SF/c where c is the speed of light (299792458 m/s). So at 1UA a 1367
W/m2 solar flux is a 4.56 10-6 N/m2 solar radiation pressure.
