Constructor Detail

DSSTPropagatorBuilder

public DSSTPropagatorBuilder(Orbit referenceOrbit,
                             ODEIntegratorBuilder builder,
                             double positionScale,
                             PropagationType propagationType,
                             PropagationType stateType)

Build a new instance.

The reference orbit is used as a model to create initial orbit. It defines the inertial frame, the central attraction coefficient, 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.

Parameters:

referenceOrbit - reference orbit from which real orbits will be built

builder - first order integrator builder

positionScale - scaling factor used for orbital parameters normalization (typically set to the expected standard deviation of the position)

propagationType - type of the orbit used for the propagation (mean or osculating)

stateType - type of the elements used to define the orbital state (mean or osculating)
