Method Detail

guessFrame

@DefaultDataContext
public static Frame guessFrame(String name)

Default string to Frame conversion for SP3Parser or RinexClockParser.

This method uses the default data context.

Various frame names are supported:

• IER##, ITR##, ITRF##, IGS##, IGb##, or SLR##, where ## is a two digits number, the number will be used to build the appropriate ITRFVersion
• GCRF (left or right justified) for GCRF inertial frame
• EME00 or EME2K for EME2000 inertial frame
• for all other names (for example if name is UNDEF or WGS84), then a default ITRF frame will be selected

Note that using inertial frames in classical products like SP3 files is non-standard, it is supported by Orekit, but may not be supported by other programs, so they should be used with caution when writing files.

Parameters:

name - of the frame.

Returns:

ITRF based on 2010 conventions, with tidal effects considered during EOP interpolation

12.1

guessFrame

public static Frame guessFrame(Frames frames,
                               String name)

Default string to Frame conversion for SP3Parser or RinexClockParser.

Various frame names are supported:

• IER##, ITR##, ITRF##, IGS##, IGb##, or SLR##, where ## is a two digits number, the number will be used to build the appropriate ITRFVersion
• GCRF (left or right justified) for GCRF inertial frame
• EME00 or EME2K for EME2000 inertial frame
• for all other names (for example if name is UNDEF or WGS84), then a default ITRF frame will be selected

Note that using inertial frames in classical products like SP3 files is non-standard, it is supported by Orekit, but may not be supported by other programs, so they should be used with caution when writing files.

Parameters:

frames - frames factory

name - of the frame.

Returns:

guessed frame

Since:

12.1

frameName

public static String frameName(Frame frame)

Guess a frame name.

If the frame is not compatible with guessFrame(Frames, String), an exception will be triggered

Parameters:

frame - frame from which we want the name

Returns:

name compatible with guessFrame(Frames, String)
