TNW : x-axis along the velocity vector, W along the orbital angular momentum vector and N completes the right handed system.

Method Detail

values

public static CCSDSFrame[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CCSDSFrame c : CCSDSFrame.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CCSDSFrame valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

isLof

public boolean isLof()

Check if the frame is a Local Orbital frame.

Returns:

true if the frame is a Local Orbital Frame

getLofType

public LOFType getLofType()

Get the type of Local Orbital frame.

If the frame is not a Local Orbital frame (i.e. if this method returns null), then the getFrame method must be used to retrieve the absolute frame.

Returns:

type of Local Orbital Frame, or null if the frame is not a local orbital frame

See Also:

isLof()

getFrame

public Frame getFrame(IERSConventions conventions,
             boolean simpleEOP)
               throws OrekitException

Get the frame corresponding to the CCSDS constant.

Parameters:

conventions - IERS conventions to use

simpleEOP - if true, tidal effects are ignored when interpolating EOP

Returns:

frame corresponding to the CCSDS constant

Throws:

OrekitException - if the frame cannot be retrieved or if it is a Local Orbital Frame

isLof()
