Constructor Detail

KeplerianPropagatorBuilder

public KeplerianPropagatorBuilder(Orbit templateOrbit,
                                  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 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:

templateOrbit - reference orbit from which real orbits will be built

positionAngleType - position angle type to use

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

Since:

8.0
