All Implemented Interfaces:

IBodyCoordinates

public class VSOP2000
extends AbstractOrbitCoordinates

This class provides coordinates for a single body. It is initialized with the VSOP2000 data file for that body.

public VSOP2000()

Method Details

setDataFile

public void setDataFile(String dataFile)

initialize

public boolean initialize()

Initializes the data, if needed.

Returns:

True if the data is initialized and ready to use. False otherwise.

position

public void position(Instant date,
 Vector3b out)

Gets the rectangular heliocentric coordinates (geocentric for the Moon) of the body, in internal units (see Constants.U_TO_M).

Parameters:

date - The date as a Java Instant.

out - The vector to return the result.

time

public static double time(double julianDate)

getEclipticSphericalCoordinates

public Vector3b getEclipticSphericalCoordinates(Instant instant,
 Vector3b out)

Description copied from interface: IBodyCoordinates

Returns the ecliptic coordinates of the body in the out vector for the given date.

Parameters:

instant - The instant.

out - The out vector with the ecliptic coordinates in internal units.

Returns:

The out vector for chaining.

getEclipticCartesianCoordinates

public Vector3b getEclipticCartesianCoordinates(Instant instant,
 Vector3b out)

Description copied from interface: IBodyCoordinates

Gets ecliptic cartesian coordinates for the given date.

Parameters:

instant - The instant.

out - The out vector where the ecliptic cartesian coordinates will be.

Returns:

The out vector for chaining, or null if the date is out of range, in case of non-elliptical orbits such as Gaia.

getEquatorialCartesianCoordinates

public Vector3b getEquatorialCartesianCoordinates(Instant instant,
 Vector3b out)

Description copied from interface: IBodyCoordinates

Gets equatorial cartesian coordinates for the given date.

Parameters:

instant - The instant.

out - The out vector where the equatorial cartesian coordinates will be.

Returns:

The out vector for chaining, or null if the date is out of range, in case of non-elliptical orbits such as Gaia.
