EcksteinHechlerPropagatorBuilder
public EcksteinHechlerPropagatorBuilder(Orbit templateOrbit, UnnormalizedSphericalHarmonicsProvider provider, PositionAngleType positionAngleType, double positionScale)
Build a new instance.The template orbit is used as a model to
create initial orbit
. It defines the inertial frame, the central attraction coefficient, the orbit type, and is also used together with thepositionScale
to convert from thenormalized
parameters used by the callers of this builder to the real orbital parameters. The default attitude provider is aligned with the orbit's inertial frame.- Parameters:
templateOrbit
- reference orbit from which real orbits will be built (note that the mu from this orbit will be overridden with the mu from theprovider
)provider
- for un-normalized zonal coefficientspositionAngleType
- position angle type to usepositionScale
- scaling factor used for orbital parameters normalization (typically set to the expected standard deviation of the position)- Since:
- 8.0
