DopData

public DopData(PsimuPropagationData propData,
       double minimumTimeStep,
       double maximumTimeStep,
       double[] vecAbsoluteTolerance,
       double[] vecRelativeTolerance,
       double absMassTolerance,
       double relMassTolerance)
        throws PsimuException

Creates a new instance. Tolerances are complete

Parameters:

propData - propagation data.

minimumTimeStep - minimum timestep (s)

maximumTimeStep - maximum timestep (s)

vecAbsoluteTolerance - absolute tolerances (position -> m, velocity -> m/s)

vecRelativeTolerance - relative tolerances

absMassTolerance - absolute mass tolerance (kg)

relMassTolerance - relative mass tolerance

Throws:

PsimuException - if complete tolerances were required but not given

DopData

public DopData(PsimuPropagationData propData,
       double minimumTimeStep,
       double maximumTimeStep,
       double positionError)
        throws PsimuException

Creates a new instance. Tolerances are not complete.

Parameters:

propData - propagation data.

minimumTimeStep - minimum timestep (s)

maximumTimeStep - maximum timestep (s)

positionError - local position error

Throws:
