Class FundamentalNutationArguments

java.lang.Object

org.orekit.data.FundamentalNutationArguments

All Implemented Interfaces:

Serializable

public class FundamentalNutationArguments
extends Object
implements Serializable

Class computing the fundamental arguments for nutation and tides.

The fundamental arguments are split in two sets:

• the Delaunay arguments for Moon and Sun effects
• the planetary arguments for other planets

Constructor Detail

FundamentalNutationArguments

public FundamentalNutationArguments(IERSConventions conventions,
                                    TimeScale timeScale,
                                    InputStream stream,
                                    String name)
                             throws OrekitException

Build a model of fundamental arguments from an IERS table file.

Parameters:

conventions - IERS conventions to use

timeScale - time scale for GMST computation (may be null if tide parameter γ = GMST + π is not needed)

stream - stream containing the IERS table

name - name of the resource file (for error messages only)

Throws:

OrekitException - if stream is null or the table cannot be parsed

FundamentalNutationArguments

public FundamentalNutationArguments(IERSConventions conventions,
                                    TimeScale timeScale,
                                    List<double[]> coefficients)
                             throws OrekitException

Build a model of fundamental arguments from an IERS table file.

Parameters:

conventions - IERS conventions to use

timeScale - time scale for GMST computation (may be null if tide parameter γ = GMST + π is not needed)

coefficients - list of coefficients arrays (all 14 arrays must be provided, the 5 Delaunay first and the 9 planetary afterwards)

Throws:

OrekitException - if GMST function cannot be retrieved

Since:

6.1
