Class PredictedEOPHistory

java.lang.Object

org.orekit.frames.EOPHistory

org.orekit.frames.PredictedEOPHistory

All Implemented Interfaces:

Serializable

public class PredictedEOPHistory
extends EOPHistory
implements Serializable

This class extends an EOPHistory for some weeks using fitting.

The goal of this class is to provide a reasonable prediction of Earth Orientation Parameters past the last date available in regular EOPHistory, which just generated corrections set to 0 when they have no data.

The prediction is based on fitting of last data, with both secular (polynomial) and harmonic (periodic) terms. The extended entries are generated at one point per day and are continuous (i.e. no leap seconds are introduced)

After construction, the history contains both the initial raw history and an extension part appended after it.
