Constructor Detail

TabulatedProvider

public TabulatedProvider(Frame referenceFrame,
                         List<? extends TimeStampedAngularCoordinates> table,
                         int n,
                         AngularDerivativesFilter filter)

Creates new instance.

This constructor uses the first and last point samples as the min and max dates.

Parameters:

referenceFrame - reference frame for tabulated attitudes

table - tabulated attitudes

n - number of attitude to use for interpolation

filter - filter for derivatives from the sample to use in interpolation
