public EcksteinHechlerPropagatorBuilder(Orbit templateOrbit, UnnormalizedSphericalHarmonicsProvider provider, PositionAngleType positionAngleType, double positionScale)
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 the positionScale
to convert from the normalized
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.
