java.lang.Object

org.orekit.propagation.semianalytical.dsst.utilities.ShortPeriodicsInterpolatedCoefficient

public class ShortPeriodicsInterpolatedCoefficient
extends Object

Interpolated short periodics coefficients.

Representation of a coefficient that need to be interpolated over time.

The short periodics coefficients can be interpolated for faster computation. This class stores computed values of the coefficients through the method addGridPoint(org.orekit.time.AbsoluteDate, double[]) and gives an interpolated result through the method value(org.orekit.time.AbsoluteDate).
